I'm well pleased with this little unit. I bought it specifically to use as a laser level. I'm building an outdoor G-scale model railroad on an elevated trestle track. I'm planning on using this laser level to make sure the track is level. I haven't yet used it on the actual project yet, but I have tried this laser level indoors. I'm pleased with the very bright laser light. I set it on a stool using it's own level bubble to project horizontal laser beam to a wall about 12 feet away. I measured the line where it hit the wall and it was 29 inches from the floor. Then I moved the stool over to where I had just measured and pointed the laser in the opposite direction (back to where I had started). I made sure the level was a centered as I could get it. Then I went back and measured the height of the laser line. This time it measured 30 inches. I tried this several times trying to use the bubble to level the laser as best I could. I got varying results. But typically within an inch or less going back and forth. So it's not going to be right on the money. The reason for this is because the level bubble just doesn't provide a precise enough measurement for insuring that the level if perfectly level. But I can work with the one inch error over 12 feet. In fact, I only plan on using this for 8 foot spans which might do a bit better. I mainly bought this for the laser light which works very well. I might be able to attach it to something with a more refined bubble level on it to increase the accuracy. I think it's just a matter of making sure the tool is perfectly level. The Bubble that's on it just doesn't provide that kind of precision. But for $13 I'm not complaining. The laser light beam is strong and produces a nice fine line, so that's worth it right there.
Also, I tried this outdoors in sunlight and it doesn't do very well because although the light seems bright indoors, it just can't compete with sunlight. However, to over come this I am using a reflector (from one of those driveway reflectors you can purchase at any hardware store). Even on a sunny day you can see the laser beam against a driveway reflector. So holding that up where you expect the beam to be sure reveal the beam even on a sunny day. Although even that is faint, but you can see it. At dusk the beam shows up naturally with no problem.
For $13 I give it 5 stars. It will serve the purpose I bought it for.
