Rated 3.8 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by Works great I purchased this item to check for wet core on a fiberglass boat I was interested in buying. I found some spots that needed some attention. When the survey was done I followed the surveyor's $500 instrument with the Ryobi and the readings matched both on the dry core area and also where the internal core is wet. It's simple to use and allows measurements without damaging the hull (Damage would be done with a pin type meter or with core drilling.) January 13, 2015
Rated 1.0 out of 5.0 by Useless I've been using a protimeter surveymaster for many years, and was looking for an inexpensive backup device, but this isn't it. The protimeter showed 10% - 12% while using it on drywall, but the ryobi showed nothing. I got a paper towel wet and put it underneath a very thin floor mat; the protimeter easily identified the location of the wet paper towel, while the ryobi showed nothing. If it can't find moisture with a simple test like this, it's useless. May 3, 2013
Rated 5.0 out of 5.0 by NECESSARY PURCHASE WITH ICE DAMS AND WINTER DAMAGES This was simple to use. A necessary tool to evaluate water/moister behind drywalls and ceilings March 25, 2015
Rated 2.0 out of 5.0 by Limited usefulness This product seems to have limited use. I wanted a moisture meter with pins, but this was the only one they had in-store. I was trying to measure the moisture in my ceiling after a small leak in a second floor bathroom. This device is useless on uneven surfaces (i.e. popcorn ceilings or trim). It works well on wide, smooth surfaces like walls. If you're trying to check moisture on anything other than a wall, find a meter with pins. July 29, 2014
Rated 5.0 out of 5.0 by works great This product showed exactly where the moisture was in my walls and floor after the fire sprinkler broke in my home. When I opened up the wall, it was wet and the mold had begun to set in. This Ryobi poduct saved me so much from further damage to my home. The inexpensive price of the moisture meter is well worth this product. Very happy with this product and this is the first review I've ever written. January 1, 2014
Rated 4.0 out of 5.0 by Ryobi Moisture Meter For $50 or so, this is a decent meter, and one you can buy in the store. I also performed the wet paper towel test under a thin board, and it detected the water immediately. This meter does 0.5 inch depth so may not be effective through carpet, but is still great for analyzing specific areas of the house, such as known areas which may have had spillage or some flooding in the past. Example I lifted a floor vent out and put the meter under the carpet onto the wood underfloor. Also detected through the vinyl floor in the kitchen. Also measured wall and concrete successfully. Also measured the moisture readings on my back deck. It was quite consistent in taking readings when going back to spots here and there. Compared to another particular $350+ similar type meter that gave you 0.75 depth and similar functions, it's worth the low price. You also have 90 days to return it is not for you. December 19, 2013
Rated 5.0 out of 5.0 by Accurate moisture reader Bought this to measure moisture readings in drywall after a recent water leak. It works great and can easily pinpoint where the drywall is wet and where it's dry, even though none of it is wet to the touch. I've taken several readings over the past few weeks and watched the moisture level go down as the drywall dries out May 14, 2014
Rated 4.0 out of 5.0 by Easy to use, does the job. Would have preferred pin-type, but this was what they carried in the store. Used it to map out wet sheetrock in the ceiling so I knew where to tear out. Has 2 flat sensors on the back about 4 inches apart that need to lay flat on the material. Hardwood, softwood, masonry and drywall modes. Also a "hold" button so you can store a reading in case you are reading somewhere that's not visible. Worked well. Only bad thing was that it came with a cheap 9-volt battery that was dead. After replacing it worked great. July 23, 2012
