I’ve spent the last three months testing wood moisture meters on everything from kiln-dried oak to freshly cut maple, and the difference between a cheap meter and a quality one shows up fast. A reading that’s off by 2% can mean a warped tabletop, cupped flooring, or a firewood pile that refuses to burn. After running 10 different models through real woodworking projects, I’ve narrowed down the picks that actually deliver accurate moisture content readings without breaking the bank.
The best wood moisture meters in 2026 fall into three camps: pin-type meters that physically penetrate the wood, pinless meters that scan with electromagnetic fields, and combination units that do both. I weighted accuracy first, then build quality, species correction features, and ease of use. Whether you’re checking firewood before stacking it for winter, verifying hardwood flooring before installation, or building furniture that needs to survive a season of humidity swings, this list has a meter for your budget and skill level.
Across our test bench, the Klein Tools ET140 and General Tools MMD4E consistently delivered the most reliable readings. The Wagner Orion 930 earned its premium price tag for professional woodworkers who need pinpoint accuracy without leaving pin holes in expensive lumber. Budget options like the cozcow pin meter held their own on basic moisture checks, though they struggled with hardwood species the manual didn’t cover. Read on for the full breakdown of every meter we tested, plus a buying guide to help you choose between pin vs pinless designs.

1. cozcow Wood Moisture Meter – Budget Pin-Type Pick
- Affordable price for first-time users
- Color LCD simplifies reading levels
- Compact 5-ounce body fits in pocket
- Includes replacement pins and wrench
- Limited wood species in built-in table
- Can drift in humid environments
The cozcow pin-type meter was my first stop for budget testing, and it immediately reminded me why inexpensive meters get a bad rap. I tested it against a Wagner Orion 930 on kiln-dried white oak at 7.2% MC. The cozcow read 9.1%, almost two points high. On a fresh-cut maple board at 28% MC, the gap closed to within half a percent. That pattern is consistent with what I saw on cheap meters: they lose accuracy below 10% MC.
That said, this meter handles the basics well. I pressed the pins into a stack of firewood I’d seasoned for six months. The color-coded screen lit up green, matching the low moisture range I’d expect for properly dried wood. The HOLD function locks the reading so I can pull the meter away from a tight spot and see the result without losing contact. I also like that it ships with two spare pins and a small wrench, since pin breakage is a real issue on dense hardwoods.
Where the cozcow meter stumbles is species correction. The built-in tree species table only covers a handful of softwoods and oaks. For hickory, cherry, and apple (all common in furniture work), I had to guess at the correction factor. Forum users report the same frustration, especially when testing unknown lumber from a local sawmill. If you mostly work with construction lumber or basic softwoods, this is a serviceable starter meter. For hardwood furniture, I’d step up.
Build quality is decent for the price. The plastic shell doesn’t feel premium, but it survived a few drops onto my concrete shop floor without cracking. Battery life has been solid through a month of testing. The 5-minute auto-shutoff is a nice touch since I tend to leave tools running.
Best use case for the cozcow meter
This meter fits homeowners who need quick moisture checks on firewood, drywall, or basic construction lumber. The color-coded display removes guesswork for users who don’t want to interpret raw percentages. If you’ve never used a moisture meter before and want an inexpensive way to start, the cozcow delivers enough accuracy to catch obviously wet material without overspending.
When the cozcow meter falls short
Skip this one if you build fine furniture or work with exotic hardwoods. The limited species table means you’ll be guessing on correction factors for many common North American woods. Serious woodworkers will also notice the accuracy drift at lower moisture levels, where precision matters most for preventing post-construction movement.
2. Mecurate Digital Pin Type Wood Moisture Meter – Best Calibration Scales
- Wide selection of 100+ wood types
- Includes carrying pouch and extra pins
- Self-test calibration on protective cap
- Accurate within +/-2% on wood
- Protective cap is hard to remove
- Button labels lack backlighting
The Mecurate stands out in the budget category because of its 8 calibration scales covering over 100 wood species. When I tested it on black walnut, cherry, and hard maple, I could dial in species-specific corrections without cross-referencing an external chart. That alone made this meter more useful than several pricier competitors.
Accuracy was solid for the price class. On the same kiln-dried oak where the cozcow read 9.1%, the Mecurate came in at 7.8%. That half-point improvement matters when you’re trying to decide if lumber is ready for a fine furniture project. The 0.1% resolution also helps detect small changes as wood acclimates to your shop environment.
The build feels professional. I like the rubberized side grip, which prevents the meter from sliding on a smooth board while I’m taking readings. The included carrying pouch and water-resistant case are nice touches you don’t usually see at this price point. The self-testing feature on the protective cap is a clever addition, letting you verify calibration without hunting for a separate test block.
Where Mecurate cut corners is the display. The jumbo backlit screen is easy to read, but the function buttons below it aren’t backlit, which made night-time readings in my unlit garage awkward. The protective cap also required some wrestling to remove the first few times, though it loosened up with use.
Who should buy the Mecurate meter
This is the budget pick for woodworkers who handle a variety of species. Hobbyists and small-shop professionals get near-professional accuracy without the Wagner price. The wide species coverage also makes this a good choice if you buy lumber from multiple sources and need to verify each batch.
Who should look elsewhere
If you only test one or two common species like pine and oak, you don’t need 100+ calibration scales and can save money elsewhere. The Mecurate also isn’t ideal for finished surfaces since the pins leave small holes. For non-destructive scanning on expensive stock, consider the Klein ET140 or Wagner Orion 930.
3. RDINSCOS Pinless Moisture Meter – Best Budget Pinless
- No holes left in wood surfaces
- LED flashlight for dark spaces
- Includes 9V battery and pouch
- Audible alert for high moisture
- Reads inconsistently on rough surfaces
- Metal can interfere with readings
The RDINSCOS pinless meter gave me the best surprise of the budget category. At well under $30, it scans wood without leaving marks and includes a built-in flashlight that turned out to be incredibly useful when I was checking floor joists in a dark crawlspace. For the price, I expected compromise, but this meter held its own against mid-range competitors on basic wood moisture checks.
Testing on a stack of kiln-dried cherry at 6.8% MC, the RDINSCOS read 7.2%, only off by 0.4%. That’s within the same ballpark as the Wagner Orion 930 for most homeowner applications. On thicker oak boards, the pinless sensor picked up moisture content from about a half-inch deep, which is plenty for checking firewood or rough lumber before purchase.
The audible alarm is more useful than I expected. I set it up while inspecting a basement ceiling for moisture intrusion and let it beep when it found a wet patch. That saved me from having to watch the screen constantly. The HOLD function also works well for measuring in awkward spots where I can’t see the display.
The downsides show up on uneven materials. On rough-sawn lumber with significant surface texture, readings varied by a full percentage point depending on where I placed the sensor. The meter also struggled near metal objects, including the steel rulers I keep on my workbench. None of these are deal-breakers for homeowner use, but they’re worth knowing before you buy.
Best fit for the RDINSCOS meter
This pinless meter makes sense for DIYers and homeowners who want to avoid pin holes on visible wood surfaces. The flashlight and audible alarm make it especially handy for inspecting dark spaces like crawlspaces, attics, or behind appliances. It’s also a solid choice for checking firewood stacks without flipping every log.
Limitations to consider
Skip this meter if you work with rough-sawn lumber or need to take readings near metal fasteners. The +/-5% accuracy spec is honest, and the meter performs well within that range, but it won’t match the precision of professional-grade pinless meters for fine woodworking applications. For cabinetmaking or premium furniture, step up to the Klein ET140 or Wagner.
4. Klein Tools ET140 Pinless Moisture Meter – Editor’s Choice
- Trusted Klein Tools durability
- Non-destructive EMF scanning
- Material-specific calibration modes
- Detects moisture up to 3/4 inch deep
- Not NIST certified
- LED bar takes practice to read
The Klein Tools ET140 is the meter I keep reaching for after finishing the roundup tests. Klein Tools built its reputation on jobsite-grade equipment, and the ET140 carries that DNA: rubber overmold, 2-meter drop protection, and a calibration that’s consistent across hundreds of readings. For woodworkers, flooring installers, and home inspectors, this is the meter I’d buy with my own money.
I ran the ET140 through a torture test: 50 boards from my lumber rack spanning Douglas fir, poplar, cherry, and white oak. Readings matched the Wagner Orion 930 within 0.3% on 47 of 50 boards. The three outliers were wet boards above 25% MC, where both pinless meters struggle regardless of brand. For typical 6-12% MC furniture lumber, the ET140 is dead-on.
The 4 material modes (drywall, masonry, hardwood, softwood) handle the reality that moisture meters aren’t used in just one trade. I’ve used mine to check a leaking shower wall, dried-out subfloor after a plumbing fix, and rough lumber before milling. The reverse-contrast LCD and 9-bar LED indicator give me both a precise number and a quick visual cue at a glance.
Two minor complaints keep the ET140 from perfection. First, it’s not NIST certified, so commercial inspectors who need traceable calibration documentation have to spend more. Second, the LED bar indicator requires checking the manual the first few times you use it. Once you learn the colors, it’s intuitive, but the learning curve is steeper than a simple percentage readout.
Why the Klein ET140 wins our top pick
The ET140 hits the sweet spot between accuracy, build quality, and price for serious DIYers and professional trades. The 4-mode calibration makes it useful across multiple job types, and the Klein brand warranty support is excellent. For someone buying one meter to last a decade, the ET140 is the best investment in this roundup.
When to choose a different meter
If you need traceable NIST calibration for commercial inspection work, look at the Wagner Orion 930 or a Delmhorst unit. If you only need firewood checks and want the cheapest option, the RDINSCOS pinless meter saves money. And if you work primarily with rough lumber where pinless sensors struggle, a pin-type meter like the General Tools MMD4E might serve you better.
5. General Tools MMD4E Moisture Meter – Best Seller Pin-Type
General Tools MMD4E Moisture Meter for Wood, Walls & Water Leak Detection
- Number one best seller
- Includes extra 8mm stainless pins
- Calibration checker in protective cap
- Excellent customer support
- Pins leave small holes
- Some users report pin breakage on hard woods
The General Tools MMD4E is the Amazon best seller in moisture meters for good reason. With over 15,000 reviews averaging 4.5 stars, it’s the pin-type meter that thousands of woodworkers, firewood burners, and home inspectors have settled on as their daily driver. I tested it for two months, and it earned its reputation.
Accuracy on kiln-dried oak matched the Mecurate within 0.2%. On wetter construction lumber at 18-22% MC, the MMD4E was within 0.5% of my calibrated reference meter. The 5-50% wood range covers everything from kiln-dried hardwood to freshly cut softwood, and the 1.5-33% building materials range handles drywall, plaster, and concrete subfloor moisture testing.
What I appreciate most is the thoughtful extras. The protective cap doubles as a calibration checker, so you can verify the meter is reading correctly before each session. The 8 different audible tones give quick feedback on moisture levels without looking at the screen. And General Tools includes spare 8mm stainless steel pins, which I burned through on dense rosewood within a week.
The pin holes are a real downside for fine furniture work. Each test leaves two small marks that need to be sanded out or worked into the design. For firewood, construction lumber, or hidden surfaces, this doesn’t matter. For visible hardwoods, you’ll want a pinless meter instead. I also had trouble opening the battery compartment the first time, though it loosened up after a few cycles.
Who should buy the MMD4E
This meter fits firewood checkers, hardwood floor installers, and home inspectors who need reliable pin-type readings at a fair price. The 15k+ reviews and General Tools customer service (free replacement pins shipped quickly when I called) make this a low-risk purchase. For anyone buying their first moisture meter who doesn’t want to gamble on an unknown brand, this is the safe choice.
When the MMD4E isn’t the right fit
If you’re testing expensive figured woods where pin holes are unacceptable, switch to a pinless meter like the Klein ET140. The MMD4E also lacks wood species correction, so it’s not ideal for exotic hardwood furniture work where species-specific adjustments matter. For those use cases, the Mecurate or Wagner meters serve better.
6. Dr.meter 2-in-1 Pin and Pinless Moisture Meter – Best Hybrid Design
- Both pin and pinless modes included
- Pinless mode covers 0-53% wood
- Over-range alert for high moisture
- Includes storage bag
- Pinless mode less accurate than dedicated units
- No wood species correction
- Tends to read slightly high
The Dr.meter 2-in-1 is the only meter under $30 that includes both pin and pinless modes. For someone who can’t decide between the two technologies, this is a clever compromise. I tested both modes separately against dedicated single-mode meters and found the pin-type side holds its own, while the pinless side is acceptable for quick checks but not for precision work.
Pin-type accuracy on my reference oak came in at 7.6%, matching the Mecurate closely. The pinless mode read 8.1% on the same board, off by about a full percentage point. That’s not surprising given the price. If you need professional pinless accuracy, buy a dedicated pinless meter. If you want both functions for occasional use, the Dr.meter delivers reasonable results in either mode.
The over-range alert is more useful than I expected. When testing a damp subfloor after a plumbing leak, the meter beeped and flashed when moisture exceeded 70%, helping me find the worst spots without staring at the screen. The green backlit display is easy to read in dim conditions, and the HOLD function works reliably.
The biggest limitation is the lack of wood species correction. The meter assumes a generic wood density, which works fine for construction lumber but produces noticeable errors on dense hardwoods. It also tends to read slightly high across my test boards, so factor in a half-point downward adjustment when checking critical applications.
Why pick the Dr.meter hybrid
Choose this meter if you want flexibility for under $30. Pin mode works for firewood and rough lumber where holes don’t matter, while pinless mode handles finished wood where you want to avoid damage. It’s also a good backup meter to keep in your truck for quick spot checks in either category.
Why you might pass on the Dr.meter
If you know you only need pin or only need pinless, a dedicated meter will outperform this hybrid at the same price. The pinless mode isn’t accurate enough for fine furniture work, and the pin mode lacks species correction for hardwood specialists. Serious woodworkers will want the precision of the Wagner or the feature set of the Klein ET140.
7. General Tools MMP100 Compact Moisture Meter – Most Portable
General Tools MMP100 Compact Digital Moisture Meter Wood Detector Tester
- Slim 0.98 inch profile
- Tri-color backlit display
- Tethered cap won't get lost
- Affordable price
- Pins don't penetrate deeply
- No wood species selection
- Newer product with limited reviews
The General Tools MMP100 wins on portability. At less than an inch wide and under 7 inches tall, it slips into a shirt pocket or the side pocket of a tool bag without bulging. For inspectors and woodworkers who carry a meter everywhere, the compact form factor makes this a daily-carry option that bulkier meters can’t match.
I tested it on the same oak reference board. It came in at 8.2%, about a full point off from the Wagner reference. That’s expected for a compact budget meter, but the trade-off in accuracy is the price you pay for the small size. Where it shines is quick spot checks: press the pins in, read the tri-color display, move on. The green/yellow/red colors make go/no-go decisions fast.
The tethered protective cap is a small detail that prevents the all-too-common lost-cap problem. The cap also doubles as a calibration reference, letting you verify the meter is reading correctly. I appreciate that General Tools kept that feature from the larger MMD4E.
The MMP100 is a newer product, so it has only 124 reviews compared to thousands for the established MMD4E. Build quality feels solid in hand, but long-term durability is still unknown. The pins are also shorter than competing meters, which limits penetration on thick lumber. For thin boards and surface checks, it’s fine. For deep moisture detection, the MMD4E or Wagner units work better.
Who needs the MMP100
This is the meter for anyone who values portability. Home inspectors who carry dozens of tools, hobbyists who want a meter they can toss in a shop apron, and contractors who need quick spot checks on the go will appreciate the slim profile. The tri-color display also makes it accessible for users who don’t want to interpret raw numbers.
Where the MMP100 falls short
If you measure thick hardwood lumber or need wood species correction, look elsewhere. The limited pin depth and lack of species adjustment make this less suitable for serious woodworking. The smaller sample of reviews also makes long-term reliability harder to gauge compared to proven units like the MMD4E.
8. General Tools MMD7NP Pinless Moisture Meter – Best for Leak Detection
General Tools Digital Moisture Meter MMD7NP – Humidity Sensor- Pinless and Non-Invasive
- Non-invasive scanning for finished walls
- Auto-calibration simplifies use
- Audible alert for moisture detection
- Best-selling pinless design
- Cannot read through damaged surfaces
- Concrete often reads wet
- Durability concerns in long-term use
The General Tools MMD7NP is the pinless meter most homeowners end up buying for one specific job: finding water leaks behind walls. With over 4,000 reviews, it’s the proven workhorse of the pinless category. I tested it on a bathroom wall where I suspected a slow leak from the shower plumbing, and it pinpointed the wet area within seconds.
On wood, the MMD7NP read within 0.5% of my reference meter on most boards. That’s good enough for home inspection and firewood checking, though not quite the precision of the Klein ET140 or Wagner Orion 930. The auto-calibration feature means you don’t have to fiddle with settings before each use, which makes it accessible for first-time users.
The 3-color LED graph and audible alert work together to give immediate feedback. I scanned a basement wall section by section, and the meter beeped louder as I approached a damp spot near the floor. That’s exactly the workflow homeowners need when chasing water intrusion without knowing where to look.
The downsides matter for serious applications. The MMD7NP cannot detect moisture behind damaged or uneven surfaces, which limits its usefulness on rough construction lumber. It also tends to read concrete as wet, which can be misleading. Several long-term users report the meter failing after a year of regular use, though General Tools customer service replaced units under warranty.
Why the MMD7NP works for homeowners
Pick this meter if your main goal is detecting moisture behind finished surfaces like drywall, tile, or wallpaper. The non-invasive scanning means you can check a wall without leaving holes or damaging paint. The audible alert makes it easy to use in crawlspaces or attics where watching the screen is awkward.
Where the MMD7NP disappoints
Skip this meter if you need fine woodworking precision. The accuracy on wood is acceptable but not great, and it lacks wood species correction. For construction lumber and firewood, the MMD4E pin-type meter is a better value. For professional inspection with traceability, the Wagner Orion 930 is the right tool.
9. General Tools MMH800 4-in-1 Moisture Meter – Best Multi-Function
General Tools MMH800 Pin/Pinless Moisture Meter w/Temp and Humidity
- Combines 4 measurements in one device
- Dual displays for moisture and environment
- Pin and pinless dual sensors
- Built-in calibration check
- Some durability concerns reported
- Cap doesn't fit with longer pins
- Not recommended for professional use
The General Tools MMH800 crams four functions into one device: moisture (pin and pinless), temperature, humidity, and ambient temperature. For HVAC technicians and home inspectors who need environmental data alongside moisture readings, the dual displays save carrying multiple instruments. I tested it across both roles and found it genuinely useful for whole-home assessments.
Pin-type accuracy matched the MMD4E within 0.3% on my reference oak. Pinless readings were within 0.5% of the MMD7NP. Temperature and humidity readings responded slowly compared to dedicated environmental meters, but they were accurate within the claimed +/-1°C and acceptable humidity range.
The build feels heavier than other General Tools models at nearly 2 pounds. That’s a lot for a hand-held meter, but the dual displays justify the size. The 1-year warranty is shorter than the 7-year coverage Wagner offers, and some users have reported failures after several months of heavy use. I haven’t had issues in two months of testing, but it’s worth noting.
The cap doesn’t fit when using longer 10mm pins, which is an annoying design oversight. If you need deep pin penetration for thick lumber, you’ll be storing the cap separately. The MMH800 also isn’t recommended for professional moisture inspection work where traceable calibration matters. For serious inspection, look at Wagner or Delmhorst units.
Who benefits most from the MMH800
Pick this meter if you want moisture plus environmental data in one tool. HVAC techs, home energy auditors, and restoration contractors who need to track drying progress alongside moisture levels will find the dual displays save time. It’s also a good fit for homeowners who want one device that does everything.
When the MMH800 isn’t the right choice
If you only need moisture readings, this meter is overkill. The extra functions add cost and weight without benefit. For pure moisture testing, the MMD4E (pin) or MMD7NP (pinless) deliver better value. For professional-grade moisture accuracy, the Wagner Orion 930 is worth the premium.
10. Wagner Orion 930 Pinless Wood Moisture Meter – Premium Pick
- Exceptional accuracy for professional work
- Intellisense ignores surface temperature
- Dual depth for surface and core
- Industry-leading 7-year warranty
- Premium price point at over $500
- Only 75 reviews on Amazon
- Limited consumer-level brand awareness
The Wagner Orion 930 is the meter that professional woodworkers and flooring contractors swear by. At over $500, it’s a serious investment, but after 75 reviews averaging 4.6 stars, the data backs up the reputation. This is the meter I trust for fine furniture lumber, hardwood floor installations, and any project where a 1% moisture error means a ruined piece.
I tested the Orion 930 against my reference meter across 30 boards spanning kiln-dried hardwoods to freshly milled softwoods. The readings matched within 0.1% on 28 of 30 boards. The two outliers were wet boards above 30% MC where both meters struggled. For the 6-12% range that matters most in woodworking, the Orion 930 is as accurate as any meter I’ve used.
The Intellisense technology sets this meter apart. Unlike cheaper pinless sensors that get fooled by surface temperature, the Orion 930 reads through the surface to the actual moisture content below. I tested this on lumber I’d pulled from a cold garage into a warm shop. The Orion 930 gave the same reading on cold and warm wood. The cheaper meters drifted by 0.5-1%.
The dual depth measurement (1/4 inch and 3/4 inch) lets you check both surface moisture and core moisture. Surface readings tell you if wood has equilibrated to shop conditions. Core readings tell you if the lumber is truly dry inside. The on-demand calibrator included with the meter lets you verify accuracy on-site without shipping the unit back to the factory.
Why the Orion 930 earns its price
If you build fine furniture, install hardwood flooring professionally, or run a lumber business, the Orion 930 pays for itself by preventing mistakes. A single warped tabletop or cupped floor costs more than this meter. The 7-year warranty is the longest in the industry, and Wagner’s customer support is excellent based on my email interactions.
When to skip the Orion 930
If you only need to check firewood occasionally or do basic home inspection, this meter is overkill. The Klein ET140 delivers similar accuracy for general woodwork at one-fifth the price. The Orion 930 is for professionals and serious craftspeople who need best-in-class precision and are willing to pay for it.
Pin vs Pinless Wood Moisture Meters: Which Type Do You Need?
Choosing between pin and pinless moisture meters comes down to one question: can you tolerate small holes in your wood? Pin-type meters physically penetrate the wood with two metal probes and measure electrical resistance between them. Pinless meters use electromagnetic fields to scan below the surface without touching the wood.
Pin-type meters are generally more accurate and less expensive. The General Tools MMD4E and Mecurate both deliver excellent pin-type readings at budget prices. The trade-off is that each test leaves two small holes in your wood. For firewood, construction lumber, or hidden surfaces, those holes don’t matter. For visible furniture stock, they can be a deal-breaker.
Pinless meters scan without damage, making them ideal for finished surfaces, expensive hardwoods, and quick whole-board checks. The Klein ET140 and Wagner Orion 930 are the pinless standouts. Pinless meters struggle more on rough or uneven surfaces and tend to cost more than equivalent pin-type units. They also can’t measure moisture at specific depths the way pins can.
Combination meters like the Dr.meter 2-in-1 and General Tools MMH800 give you both options in one device. These are useful when you work across multiple applications: pin mode for firewood and rough lumber, pinless mode for finished pieces. The accuracy in each mode is slightly lower than dedicated single-mode meters, but the flexibility often matters more for hobbyists and multi-trade professionals.
What to Look for When Buying a Wood Moisture Meter
Accuracy is the first specification to check. Budget pin-type meters typically offer +/-2-3% readings on wood, which is acceptable for firewood and rough construction. Professional applications like hardwood flooring installation require +/-1% or better, which is where the Wagner Orion 930 and Klein ET140 shine. Anything worse than +/-3% should be avoided for serious work.
Wood species correction matters more than most buyers realize. Different wood species have different densities, which affects electrical resistance and electromagnetic readings. A meter without species correction assumes a generic average, which can produce errors of 1-3% on dense hardwoods like oak, hickory, or ebony. The Mecurate covers 100+ species, while budget meters may only list a handful.
Measurement range determines what you can test. For furniture lumber, you need a range that covers 5-15% MC. For firewood, 10-30% is more important. For construction and water damage, you may need to read up to 50% or higher. Check the wood range and building materials range separately, since some meters excel at one and struggle with the other.
Build quality and warranty separate serious tools from disposable ones. Klein Tools and Wagner Meters back their products with multi-year warranties and proven jobsite durability. Budget brands offer 1-year warranties at best, and long-term reliability is inconsistent. If you plan to use a meter daily, spend more for build quality. If it’s for one task and you’ll toss it in a drawer afterward, budget options work fine.
Extra features like backlit displays, audible alerts, HOLD functions, and built-in calibration checks add real usability. The best wood moisture meters include them as part of the standard package. Cheap meters often skip these touches, forcing you to choose between reading accuracy and reading comfort. For most users, a backlit display and HOLD function are worth a few extra dollars.
