The Best of the Best!
By far, this laser is the Best Of The Best! Hands Down! I have used a Laser Level every day for as long as I can remember!! I’m a Industrial PipeFitter! This is by far, one of the best investments you will make!

Bought it for "coolness" / Discovered usefulness
I was in the middle of a major renovation project and I was buying Bosch tools like mad. I confess that bought this laser tool more as a novelty... I really didn't think that I would find much use for it. Wow was I wrong! We used it to set stud walls, level ceilings, frame door openings, etc. What a time saver! Part of our project was renovating both of my client's bathrooms. We used it during the electrical and plumbing rough-in to precisely set electrical boxes and pipe nipples so that everything was in perfect alignment. When you walk into their finished bathrooms, vanitys, mirrors, wall sconces, switches, outlets are all perfect positioned. I am currently putting my laser to work on my own bathroom renovation. What a great tool!

Worked amazingly for 2 months, then one laser died
I used it for a total of about 6 days and I loved it until one of the lasers failed. I am surprised that a Bosch product failed so quickly and am frustrated that I must have it repaired.

Not Quite Awesome
After receiving this laser I tested the unit around the house and was pleased with the features. After a few weeks I finally had a chance to use it for real layout at work. First impression, unless you do all your work in dimly lit, dark job sites you will have a tough time seeing the lines. It's just not that bright. I had to shut down the lights in a warehouse. I'm finding it hard to justify the money spent on this laser.
The BM-1 positioning device seemed capable, but in reality it's not very functional. When the laser is threaded on the mount it tightens to the GLL but still spins on the BM-1 making it more susceptible to being moved than if you just set it alone on the floor. Seem like an odd way to execute this feature. The BM-1 has many different attachment options and just quickly clamping it to anything more than an 1/8" or so thick isn't one of them. What a shame. It would have been nice to clamp on to something and use the fine adjustment to set a level line.
I'm just not sure if I should return it or just eat the high cost and hope to find enough tasks where it's very specific mounting options will be available.

Worth its weight in gold!
Your imagination is the limit in extracting maximum value from this tool. As a commercial contractor i use it for everything from layout to finish. I own three, and they are among the best investments I have made.

Describe Yourself:
Great clarity in the green line.
The laser is everything it was advertised to be. The beams were fine and clear and extended to the 200' as advertised. I would buy this laser again!

GLL3-300GC Arrived 2 days ago
Nice unit, bright tight lines, pleased it's smaller that I thought it would be and easier to see lines. Easy to use and carry on job and in truck. Don't have a 16' room yet so I haven't checked accuracy as per manual but tested with my best spirit level and it looks good. One thing in manual confused me and I haven't tested, I think it says if I have auto leveling off (locked and "In cross-line operation, the two laser lines do not necessarily run at a right angle to each other". Makes sense I guess if you have the unit at a skew angle to the services but I don't know if that is what they are talking about. Also haven't tested the bluetooth, found out my phone OS is too old (phone is really old) but I look forward to that in the future.

can this laser plumb?
A shopper on Jun 10, 2018
BEST ANSWER: Very precisely
As a follow up to the plumb question, the pictures or descriptions don't show the ability to transfer, let's say, a point from floor to the ceiling. Something I need all the time. For example laying out recessed lights on the floor first and then transferring them to the ceiling. Does it do that?
A shopper on Feb 25, 2019
BEST ANSWER: The planes created by the front and side beams will intersect on the floor and ceiling. This is effectively a vertical point to point. Also, the front and top beams form planes that will intersect horizontally, (on the walls).
Warranty. And if not do you sell coverage?
