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.

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.

Rated 4.0 out of 5.0 by Mark999 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.

Rated 5.0 out of 5.0 by Tony Easy to use moisture meter
This is an easy to use meter which meets all expectations of measuring moisture in household walls at this price point. The large-area contacts insure a low contact resistance which prevents isolated spots from skewing the readings. Although I made no comparison with a calibrated meter, use of this meter over several weeks has shown consistency of readings over time and over areas that were suspected of harboring moisture after a winter of water build-up behind roof ice-dams. The 'hold' feature is especially useful for making measurements in hard to view areas. The grip and weight make it a natural extension of your hand. All-in-all, this meter is thoughtfully built with a home user in mind.

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.

Rated 1.0 out of 5.0 by Contractor Not accurate, sensor area too large.
This meter picks up all metal within walls - nails, corner beads, wiring, etc. Without the pins there is no way to 'pinpoint' a specific location. All you can do is get in the general area - if there is metal(even close by) you will get a false reading. Moisture meters work based on continuity so metal will cause false readings on any meter but with such a large sensor area(instead of pins), it is difficult to stay away from metal in small spaces.

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.)
