Better than expected... wish everything else was
I bought this level, and it's been great! Easy to use, very easily visible light. Unfortunately, not I see how bad some of the work is on my house, so my honey- do list is getting pretty long. Wish my contractors would've used this.

Very good so far. Easy to see & accurate.
So far this is a great tool. Sets up easy, accurate, easy to see in high ambient light. I wished they had a 3 line green beam that was specced at 100'. GX version substitutes a soft case for the hard case. The soft case only holds the level itself, not the target and certainly not the BM3 positioning device.

Describe Yourself:
I’ve been wanting a green laser for awhile. I have a few red lasers I use all the time but hard to see in bright light. The cost of this green laser is great and you won’t believe how visible it is even in brightly lit areas.

Missed on this one.
I have a few Bosch lasers, and heard green was brighter so I grabbed this one at Home Depot. First impression out of the box was why they sell it with the mounting kit using the 1/4” thumb screw, which offsets the laser from center. This laser is heavier than the other ones I have, and mounting it to the bracket isn’t a as solid as I would like. It is bright. It is accurate and consistent. It does use batteries like no other laser I have had. Why .... why does it stay on for as long as it does. 20-30 min would be ideal. I’ve replaced more batteries in this laser alone than all 3 of my others combined over a year and a half. And I’ve had this one 4 weeks .... 5/8 mount, more robust mount bracket and an option to shut the lines off after a certain time and this is a home run laser. But for now ... last one I take out of the gang box ...

Have two of these replacing the older GLL2-50's. Can't get any battery to last more than 20 minutes in these levels.

I got this laser 3 weeks ago and i love it. Laser stays on long time without turning off. Line is very visible. Works great for leveling big areas. Come with mounting bracket that you can hang it on a wall
