Review on BDL170 Bullseye Auto Leveling by BLACK+DECKER by Kino Gerami

I bought this to replace a lost one that was actually stuck to the wall. I found it too, BUT I didn't read carefully enough. If you want it to hang on the wall, you need to drill a hole in the wall or use the command bar. I read the instructions twice. I tried using it to make a line to hang a frame that needed two anchors in the wall. "Protractor" function is so opaque and hard to read. You can't tell for sure if something is actually on the same plane. I had to measure it three different ways and then divide the difference to get a straight line. Not worth the money. It will not stick to the wall without damage. It's difficult to use.
