I think at the price I should have guessed that something was wrong. It places 1 dot (or line or cross) directly in front of where you point. Just as if you had a laser pointer. So it's a cheap laser pointer and a cheap three-sided bubble level that's too short for accuracy. Oh, and a cheap 5ft tape measure. I already had these things laying around, and putting them together in a block doesn't make it any more useful. It also comes with a screwdriver-like tool with a unique wedge head that I've never seen before but doesn't fit. somewhere on the device so I have no idea what it's for.
