great little tool - I have not tested the accuracy yet but for what this laser can do it is great. You get a quick level for anything that need to be level on a job. Furthermore you get the vertical and horizontal if you need it like for tiling walls. So far I am pretty happy with the product and it is quite cheap.

Really, really useful - Bought this to help with layout out some tilework. It s great having both horizontal and vertical lines that can be viewed on floors and walls. Wish I had bought it earlier when I was building a new deck and needed to line up the framing and decking.

Accuracy greatly exceeds specifications - I measured the accuracy of the FatMax I received. (1) The leveling (horizontal angle of the center of the projected cross) spec that is printed in the manual is 0.025-degree, and I measured better than 0.01-degree. (2) The plumb accuracy is hard to measure and no spec is given in the manual. I measured better than 0.05-degree, and it probably is much better than that. (3) The horizontal (right-to-left) line spec printed in the manual is 0.045-degrees. On my FatMax the line up to 45-degrees from straight ahead is level to better than 0.007-degrees. Beyond 45-degrees, the line curves down on both sides so that at 80-degrees from straight ahead it has dropped 0.030-degrees. I myself cannot speak to its robustness, since I have been treating it carefully, but its accuracy is much better than the company claimed.

On the Level - This did everything I wanted. I was surprised the numerous uses I found for it. I found out it works well on a camera tripod. The only drawback is it does not perform well in bright light which is true for all lasers.

Big time saver - I ve used this laser level for wall tile, floor tile, hanging cabinets, building a level bench on sloping ground and painting a 16 ft diagonal straight line. This tool is excellent and saved me a huge amount of time.As to accuracy, I ve had no problem. Regarding the complaint that two units were way off, I suspect he moved the laser as he worked on the wall. You have to leave the laser in precisely the same spot, you can t move it along as you move down the wall. I made this mistake. I wanted the line a little brighter where I was working, so I moved the tripod, thinking, it would still be at the same height. It was the same height off the floor, but the floor wasn t level, so my new line was 1/4 higher when I moved the laser.As to the complaint that you have to raise it to the height you want the line projected at, well that is just how any laser would work. It is like complaining that the problem with a screwdriver is you have to get it right up next to the screw. It may be inconvenient, but it is how it works.As to brightness, I ve had no problem indoors. it is easily visible at 20 feet. I haven t used it in a larger area. Outdoors, it is better than others that I ve used, but it is impossible to see in bright sunlight. Working in the shade it was fine.
