Review on BLACK DECKER BDL220S Laser Level by Kevin Ayala

This line laser is very handy. The wall pen is quite small and doesn't leave a big hole in the wall, and it's easy to draw vertical or horizontal planes with it. If you want a specific angle like 45, you need to set 0° with the dial on the wall mount, and from there it's not difficult at all. When the laser draws a faint line, sometimes you need to adjust the mount. but I haven't had many problems with this tool yet. Also the dragonfly will light up when you turn on the laser, which is normal, but I doubt I'll end up drawing many lines in the dark.
