Review on BLACK DECKER BDL220S Laser Level by Nate Nelson

This is a cheap handy tool for me. It helps a lot in hanging photos and shelves. As other reviewers point out, the little nail is annoying and pointless. They all mention that making an extra hole in the wall is stupid. However, I make this hole where I want the first image to be and then mark the remaining spots. Then it's not an extra hole, it's just where I hammered my first nail. What I don't like about it is that it's not strong enough to hold the level in place. I can't hang it on the wall and just walk along the leash, otherwise it will rotate by itself or fall off the wall. The design would be much better with a suction cup or something that sticks better.
