    • Pins are bad and display is not backlit.
Style: MO55 Pattern Name: Moisture Meter
The pinless function works fine however the pins continually lose contact. I have to constantly retighten the pins but they are not reliable. I can now only use it as a pinless meter. Also, because the display is not backlit, it is very difficult to read. I use this meter in Crawlspaces and attics quite frequently. Not happy with it’s performance. ... show more

Style: MO55W Pattern Name: Moisture Meter
It's great in terms of bang for your buck. I'm on my second one and they're accurate and tough. Been dropped multiple times and still working. My only gripe is the location of the power button. Being on the front, it has a habit of turning itself on while in my tool belt. This is a problem with every moisture meter I own, and as a home inspector it is really annoying. ... show more

Style: MO55 Pattern Name: Moisture Meter
I use this every single day while performing home inspections. In fact, it is probably my favorite tool. The problems I have uncovered and the knowledge I have been able to provide with this has payed for it 100 times.Having both the pin and pinless mode is imperative. If it hasn't rained in a few days they without pinless you would never know if there is still leaking. Results are highly reproducible and accurate. One of the nicest things is the fact there is a chart on the back with levels of moisture for different materials/ modes. This is helpful as the pin/pinless modes read moisture differently therefore 30% on one is different from the other. The beeping is a nice touch in hard to reach areas. It would be nice if you could silence it though as can be a bit annoying while using for extended periods. Lastly, the power butting could be moved or redesigned. I like to carry this with me a lot and is easily turned on in a pocket. Not a huge deal but have gone through a few batts quickly when it gets wedged against something in my tool bag. P.S. pin cover is hard to open but that does prevent it from getting lost/ someone sticking themselves. I find it easiest to push on the front and rotate back, usually pops right off that way. Just make sure not to pin yourself. ... show more

The device showed me where my moisture was lower and where their might be a problem. It was a good indicator and I found the leak source under my kitchen floor.

    • good product worth the money
Style: MO55 Pattern Name: Moisture Meter
I like the display screen is large and the silicone grips in orange help hold onto the device. I also like the testing device is very handy inside the pin cap and not in a separate little baggie that gets lost and no body knows what it is. The only advice I'd have is to make the pin cap cover attach with a dangling cord so that it doesn't get misplaced and is always attached. ... show more

The Extech M0290 is a great moisture meter. It genuinely serves its purpose within the industry. My father has had his for well over 15 years. The orange rubber boarder is fading away it’s that aged however, when I took this unit out of its case and placed the battery in back, I turned it on and selected non intrusive mode and it instantly picked up moisture when the unit wasn’t touching any materials. ... show more
