HANDY AND RELIABLE
DID NOT HAVE ANY PROBLEM USING THIS PRODUCT. IT WORKED EVERY TIME I USED IT. I LIKE THE LITTLE INFRARED LIGHT
Stud finder
Good product works just fine I'm the one who sucks at handyman work,no all jokes aside there are much more expensive stud finders out there .This is all you need .
Works great
Bought it specifically because it tells you if there is electrical behind the beams-- and it also tells you if you are in the center of the beam-- very useful for placing photos or other things on the wall. Have used it several times with no problem at all. Works great.
Weak at best
This is the first stud finder I've owned and unfortunately, I'm not impressed. The unit fails to locate studs where I know they exist and is marginal at best in locating other studs behind dry wall.
great tool
This tool is very easy to use, accurate and well priced. I highly recommend it!
