What Customers Are Saying
The product has a mix of positive and negative feedback. On the positive side, it is praised for its ease of use, bright and visible laser lines, and self-leveling functionality, making it helpful for various home improvement tasks. However, some users found the instructions difficult to use and the mounting clamp challenging. There were also concerns about the laser's limited range and visibility, especially when used outdoors or on certain surfaces, as well as doubts about its accuracy compared to more expensive models. Overall, it seems to be a decent mid-range option for many DIY projects, but may not meet the needs of more demanding users.

Big disappointment
Would Not RecommendThis level is advertised as having a range of 50 feet, but it is barely visible at 15 feet in the shade.
I returned the cheaper version and bought this one. this one is far superior. I like this one more than the stanley fat max that I had for many years.

Disappointing
I returned this item almost as soon as I opened up the package. A agree with the other reviews that state the instructions are illegible and make no sense whatsoever. The "clamp" that comes with the unit is not usable, or just usable if you happen to be installing a drop ceiling (who does that anymore?). OVER ALL VERY POOR EXECUTION. BOSCH PRICES THIS FOR THE SELF HOME IMPROVEMENT MARKET AND THEN ASSUMES WHOEVER BUYS IT WILL KNOW HOW TO USE IT WITHOUT CLEAR INSTRUCTIONS. DUH! The company sho...

Bosch Laser
Would RecommendHad to buy this to replace a virtually identical model which met with an unfortunate fall from heights. Don’t know how I’d do a project without one of these any more!

Good machine
Would RecommendWe wanted to use it on the ceiling because we were placing wallpaper up there. It’s not so good for ceilings. But we were, after some working around, able to use it to mark some lines on the ceiling and find the center. So, that was very helpful. Will use it on our bathroom redo and kitchen too.

it works great. if you are relying on a distance over 30' get the next model the line starts to get wider. we are leveling an old third floor apartment and the floors are up to 5" out. leveled a 22' x 44' in three days using this laser and it is 100% and never even pick up a level.
