It works very well

great product very rugged.

Great for hard wood

Every home owner needs one of these if the had a leak. it will show where the moisture is higher behind sheet rock/wood/vinyl/ laminate/hardwood/even tile if you compare to the dry section first.

Great tool!

We recently had a water intrusion in our house. We hired the pros to come in and do the dryout. Im sure this isnt the same grade tool they use. Theirs probably has some certification or something to justify the $800 or whatever price they pay for it. I dont care if this is off by a few percent or something... it told me the same spots were wet, which is what I care about. I cant tell you how accurate the numbers are, but this thing works. I just press it against what I think is a dry area to establish a baseline, then look for moisture. We are staying at my mother in laws, and there was a leak under a cabinet, and I was able to use it to test for moisture before putting things back. Very handy. I read another review where someone used it to test if their laundry is dry. Im going to try that next.

I use this to test wood from the wood pile before using in our wood stove. I dont know about accuracy, but relatively Im sure its accurate. A heavy piece certainly shows high moisture content. Very light ones measure what I would expect. So Im guessing its accurate. But what is great is how easy it is to use. Just slide it over the end of a cut log and you can very quickly see the moisture distribution. If there is still a we spot at the center for instance, it shows up right away. Those I put next to the stove to dry for a day or two before I use them. This is really the best answer IMO for my use case. A probe meter may be more accurate, but I need quick reading across the wood. Probe meters dont do that. This does. Ive dropped it a few times, still ticking. Highly recommended. Would buy again.

I have a chronic rain water problem in one exterior wall, it originates from either around a clerestory window or where the porch meets the wall. While I waited for the next rain storm, I thought I would see if this moisture meter works. I took a 1x2 foot piece of sheet rock and squirted about a third of the paper backing with water - not too much just enough to dampen it. After about an hour, I ran the meter over the plaster side around the area that I knew was dry and got a reading of 0% moisture; no surprise there. But as I moved to the dampened area, I got readings from 19 to 25 % moisture. The next day, I checked the sheet rock with a thermal imager and it indicated dampness around the edges and a couple of faint,I assumed ,damp spots - there was absolutely no visible or tactile moisture on either surfaces. I ran the Klein meter around the same areas, and the moisture meter showed positive in those identical spots. I was quite impressed. So, my conclusion is your sheet rock walls should be around 0%; this meter will indicate even the slightest bit of residual moisture.

I bought this after a water leak and it works great. Very easy to use. Klein is a good company that I trust so that helps

Great for checking water/moisture under hardwood flooring that is 3/4 inches thick. The screen is easy to read.
