What Customers Are Saying
Customers overwhelmingly praise this laser level for its ease of use, accuracy, and durability. Most highlight the self-leveling feature and rugged rubberized casing as reliable for hanging pictures, tiling, and leveling surfaces indoors. The intuitive operation requires no manual, and reviewers call it a professional-grade tool at great value. However, some report poor visibility in bright daylight beyond 10 feet, and a few experienced battery contact issues or alignment problems. Despite these drawbacks, most customers consider it an indispensable home improvement tool.

The Bosch self-leveling cross-line laser level makes a sharp, red line that's easy to see. I used it to hang a set of 3 pictures and curtain rods. Having the right tool for the job makes a big difference, and a laser level is the right tool for hanging anything on a wall. I attached it to a camera tripod for stability and height. One question that remains unanswered is its longevity. I have only had it 2 weeks and used it once, so I have no idea whether it will be worth the $60 I spent on it. I...

Easy to use, easy to see, awesome price
Having the flexibility of mounting to the wall using a screw, the magnetic back, or a tripod is fantastic. I used this is a well lit room that was 12x24 and was able to see the lines perfectly. I haven't tested it on larger rooms yet but will do that soon enough.
Simplify hanging items on a wall
It’s one of those tools that actually makes a project feel faster and more satisfying. It has taken the guesswork and frustration out of decorating walls. Instead of wrestling with a traditional bubble level and a pencil, I just flick a switch and get a perfect, steady line across the entire room.

Great laser level
Like this level the best so far. Will stay lit when it is level and flickers on and off if it’s not. Nice cross hair. Helped out a lot framing basement during remodel.
Does not work with Duracell batteries
I know this review title is odd, so allow me to explain. First off, I'm highly disappointed that I bought the premium Bosch brand for a premium price and encountered such a problem. This is the most puzzling thing for me. I'm pretty handy with both tools and electronics. I bought this Bosch level because Bosch typically makes high quality tools. You get what you pay for, right? Got it home and inserted 2 brand new Duracell AA batteries because typically, the cheap batteries these tools come...
Bosch GLL50-20 is a good entry level laser!
The Bosch GLL50-20 is a basic, entry level, compact, and lightweight red line crossline laser that is good for use by the homeowner. It helps you quickly and accurately project a combination of horizontal (level) and vertical (plumb) red layout lines at the same time up to maximum of 50 feet ahead of you while indoors. This laser has an accuracy of plus/minus 5/16” at 30 feet and laser Owner’s Manual is provided on the www.bosch.com website. It comes with 2, alkaline “AA” batteries or you can...

Very bright light at night!
Husband used this product for leveling up and marking out all the lines and marks. Works incredibly well at night, nice bright easy to see lines. During the daylight hours, not so much. We were able to provide some shade to get the lines to show up, so, it definitely did its job and made the project easier. Would recommend to anyone who needs to mark out straight lines.

Very short range outside
Works great inside, but effective range outside is more like 15 feet - even with fresh batteries - unless you want to work at night!

Level up
Needed a unique gift for the builder who has everything. Multi laser for great leveling. Get the tripod to go with it.
