Great little laser for setting wall tile
auto level @ + - 4 degrees, I mounted my unit on a tripod but the clamp provided works well also. This unit will burn through batteries, expect 3-4 hrs of runtime per set of AA batteries. I used this laser to set bathroom wall tile. No problems at all with the accuracy maintaining plumb and level lines. I haven't really tested it's ability or accuracy to work anymore than 4-8 ft away from my work surface, but I would guess the lines may get a little fuzzy and wide. I think the paperwork said 3/8-5/16 @ 40ft.. This is overcome by using the center of the beam and should be fine for most small projects.. All and all a great little laser for the price.

Not accurate enough for professional use

Green is good.
Pretty cool device. Very bright and easy to see. The one major function I wish it could do is point up or down. You have to have it at the height level you want. I knew this going into it, didn't realize hope much that matters until I had practical experience with it.

Just OK
It’s just OK. Expected better. It won’t self level if you are more then 4 degrees off of level. So, aiming up a wall to hang a picture requires you to put the laser at almost the same height as the picture itself. Green laser is easier to see, but not much brighter at 15 feet or more.

“Lazers”
Got this to level my backyard to put in pavers. The laser is very visible outside in daylight for about six feet. Very bright and easy to see in the shade. Had to work early in the morning. It worked and was priced well. Seems well made too!

Not very good for outside work
When outside the laser is not visible at 10'.

Out of level by more than 1/2" in 20' A waste of money.
Not nearly accurate enough to use for anything that matters. The right side is always high by 1/2" in 20 ft when compared to a $3k Bosch tripod mounted laser. It's disappointing that there is no way to adjust alignment.. wasted money.

The horizontal laser line is very difficult to see outdoor daylight
This works very well indoor but for outdoor the horizontal laser beam is very weak. At first I thought that this unit was defected because when using outdoor with daylight I was able to see the vertical laser beam fine but the horizontal beam was very weak. I returned and got another one and still see the same issue with the horizontal beam.
