Overall worked well. I was able to use it to level a patio I was pouring. I had to set this up after the sun went down to see the beam outside, but it worked. During the day, forget about it.

I wish the vertical line stayed on when you tilt the laser over. May be due to the auto leveling but anything over 15 degrees of angle it makes the laser lines flash

Excellent product. It works exactly as I had hoped.

The green color makes it easier to find the laser on bright conditions. Tripod and magnetic support helps you a lot to position the device. I get a good deal while on discount so it was totally worth it.

Range isn’t as advertised. Horizontal lines are visible 10 feet only. Eats battery like crazy

Used the laser level extensively for a big walk in shower tile job. Pretty intuitive to use and manage with the right tripod(s). I used a small flexible gorilla pod for near the floor to get low level lines on the wall and a taller tripod I’ve used for photography on the taller level lines. Really made the project move smoothly versus having to use a 2 or 4’ level to constantly check level across rows of tiles as well as vertical lines for bullnose finishing tile.
