Easy to use right out of the box
My laundry room flooded and I’m replacing the flooring. The moisture is in the sub flooring – along with the existing flooring. The floor company told me to buy a moisture reader to monitor the sub floor, because they cant install replacement/new flooring until the reading is less than 5%. When I first got this reader it was over 50% on the sub floor, so I have been using heaters and fans. Now it is down to 25% – but the best thing is… I know nothing about flooring or moisture or how to use moisture readers, but this is super intuitive and easy to use.> Just hit one button to tell it what material it is “wall, hardwood, softwood”, etc. then it’s super easy – just lay the reader where you want it to read and it does the rest.> Seems very accurate. If i test, then re-test again, readings stay consistent.> Would be easy to locate a leak. You really do just run it over surfaces and it will change in real time. I personally dont have an active leak, but this is accurate and can pin point areas that are more moist than others.> In the video – the sub floor is less moist than the flooring that was soaked and is still installed. You can see how it detects different moisture levels in different areas. Very nice way to monitor as moisture levels go down.> OVERALL – so happy I went with this model, even though I was comparing it with a couple others that were a little cheaper. This one works VERY VERY well.. that’s all that is important when your in a situation where you need one of these. If you buy a cheaper one, that may not be as accurate – you will be kicking yourself later when your entire project is up in the air and your going to spend that extra $10 at Starbucks because your stressed out and need coffee 🙂

Good meter
Works as good as the boat surveyor’s meter, who I paid $1000 to survey the boat prior to purchase. Could have saved $950. Handy little tool.

Battery lasted longer than the meter
I’m an insurance adjuster and need a meter to determine where water is and isn’t. This does a wonderful job. I gave it 5 stars for it’s price and ability limitations. However after not daily use but regular use it stopped working after a year. There’s the Lost star. The pad on the back has worn thru, and it just stopped reading. It turns on and I thought it was the battery so I swapped it out with a new one. That didn’t solve the problem. I bought another one because it’s easy to use and cheap, I just would have liked it to last more than a year. And I put the old battery in the new meter and it still has most of the charge left, so storing the new battery for future use. Sad the battery lasted longer than the meter did…Now to those who would use this instead of a professional assessment, I would use this to conclude you NEED a professional, not to use yourself, because their equipment is WAY better and more accurate, and though your drywall may read dry, the problem is your wood studs inside the wall are most likely still wet and this meter won’t tell you that.This is a great reference tool, but that is all it is, a reference tool, not a professional diagnostic tool. I will however still trust it daily to tell me what I need to know for my job.Also, almost all concrete reads wet with this meter, and most thin flooring reads wet or elevated if installed over concrete. Don’t like that, but I just use a reference point I know it’s not damaged and use that as the baseline and look for elevated areas above that.

Works well
It seems to behave exactly as advertised. No prongs, just lay it against a surface, and gives you a reading.

reliable, well built, easy to use moisture meter
very pleased. bought it to check out houses as we were looking to buy one. simple to operate, seems to be good quality. and the AI questions sections on this Amazon website help explain a lot about its operation. My only quibble is that the LED screen is sometimes difficult to read from certain angles, but using the AI questions I just learned that that’s what the “hold” button is for! (place the unit to get a reading, pull it out while holding the hold button, and the screen retains the reading!). RTFM I guess. oh, also it’s important to keep the sensor area protected and clean.

Just what we needed, in a hurry because of a leak!
Very effective tool for measuring moisture. Helped us find the area our leak was in. Delivered within hours

Works very well and simple to use.
I don’t know how deep this goes through painted drywall but I feel it only detects moisture directly on the surface.The reason I say this is that I don’t believe my bathroom drywall, which is painted the same as my room, have the same moisture content inside the drywall.Works the best on wood and concrete in my opinion. Bare surfaces come up even more accurate.UPDATE: I was looking through my reviews and I noticed this Review. After months of having it, I believe there are inaccuracies with measuring wood. I thought I had a moisture problem! Anyways I had to buy a pinned meter, made by the same company. This one had a calibration that you can check the pins and accuracy. This one showed I had no moisture problems on the same wood. The technology for pinless is not as accurate when comparing to pinned models.

Ease of use
Great for the price….have purchased several of this particular meter and others of this brand….they have been great and easy to use and read.

I bought this gadget to detect water leakage within the walls of my house. While the gadget works well, I am not too sure of the accuracy of its readings. Nevertheless, it serves well if you are interested in checking out for any water leakages without asking for true readings.
