I love having this for when I am wanting to hand a picture...especially if it's heavy and I need to anchor it. It's very simple and easy to use. With a quick click on the side and slide it across the wall, you'll know where the stud is. Very handy to keep in toolbox!!
First of all the instruction sheet is not well written and I believe the unit itself is defective. It does not show any activity when I try using it. When I push the on switch it does not respond as the instruction sheet says it will do. I plan to return it, Luther Stephens
