Phone Works™ Stud Finder
Phone Works™ Stud Finder is rated 2.0 out of 5 by 1.
Rated 2 out of 5 by from Love the idea, but needs work. Bought this and was excited about the idea. Stud finders are notorious for not lasting. This really didn't work well for me. I used it on an Iphone 6. I was doing a commercial job with 5/8" sheetrock, steel studs, and insulation. If a stud finder isn't going to work well, that's where it will happen, but it advertises it will work in those conditions. I returned it the next day. I'll wait for next generation to come out and give it another go. In general love Ryobi and their products.
