BOSCH GLL50-20 50 Ft Self-Leveling Cross-Line Laser, Includes Integrated Magnetic Mount & 2 AA Batteries

This laser level is outstanding, portability, works great, always level…. this tool gets used the most in my toolbox. The battery life is outstanding. The brightness is good and the accuracy is correct. I’ve checked it with my other levels and it’s always right on.

Needed something quick and reliable. This was both. I used it to help me bolt hangers to the ceiling in my garage for those cable lifting storage racks. Worked perfectly for what I needed. Could clearly see the red lines. Took getting used to how to set it so it would cross all premarked spots so I knew it was lined up across the rafters in a straight line. I've always wanted something like this but never "needed" one until now. I'm sure I'll use it often.

This laser level is perfect for occasional use that isn't complex. If you are doing anything more than a small home project or intend to use it more frequently, invest in higher model that also uses a green beam. For a "budget" model, this fits the bill just fine. My only gripe is that occasionally it likes to throw a hissy fit. This model flashes the lines every couple of seconds if it detects it can't auto-level itself. There are times when I have perfectly level lines (and have verified through other means) and it blinks as if it isn't level. Annoying, but for the little I use it, it's tolerable.

I bought this level to help me install wallpaper. It took a bit of practice, but once I understood how to use it, it was very simple and extremely helpful. The level has an adjustable clamp which allows you to mount it on almost anything (I’ve mounted it on a wooden stair railing, a step ladder, etc.). If the red lines don’t show on the wall, it’s because you don’t have the level *ahem* level. If the lines don’t show, it’s not broken, it’s user error. The lines are clear and crisp and allowed me to get a perfectly plumb line every time. The wallpaper I installed has a very intricate pattern, so matching the seams had to be flawless. By using this level, every seam was flawless, even the 12-foot long wall!

This was one of those purchases that I said how have I lived so long without this. Great value, easy to use, love it…

I bought this because I had to drill two holes in my wall, about 67" AFF and about 70" apart. Their measurements to the ceiling were 1/4" different. Was the floor unlevel or was it the ceiling? Laser level to the rescue. Here are some lessons learned and comments on other reviewers' critiques: • This thing seems accurate when placed about 10' from wall as measured with a Stabila 6' level. (I know, I could have used the Stabila for my job, but I wanted the laser.) • This is not like a flashlight, i.e., you can't hold it in your hand and shine it at any height on the wall and see a level line. You have to raise it to the height where you want the horizontal line to appear. This is where a tripod comes in handy. I used an old Amazon Basics 60" adjustable camera tripod. It worked great. The crank on the tripod lets you raise/lower the level precisely. • The laser mechanism rides on a gimbal. If you cock/tilt the laser body and the gimbal doesn't have enough "wiggle room" to keep things level, the laser blinks in warning. People who complain about this behavior are not keeping their laser upright enough. Probably aren't using a tripod. • Finally, and the reason I wrote this review, is the quality of the box — it is great! If you want to put your level away until you use it again at some later date, everything packs neatly and safely back into the box. Just toss that box in a drawer and everything will be kept safely together. It's better than most blow-molded plastic cases you get with tools, IMHO. All in all, with this laser I was able to quickly and confidently mark these two holes and hang a 6' x 4' framed tapestry perfectly. I actually delayed completing the job until I received the laser and I'm glad I did.

Nice unit. the Line (Red) is not easy to see in sunlight type conditions. During the rebuild of a home the only light source was the sun and trying to see this units lines in sunlight is not possible. The unit works very well in low light conditions, but is none existent in brighter lighting. The unit works as described and I was very let down as all my other bosh products are amazing. This unit was sub par for the price. The setup and use of the product is so simple and was just what i wanted.

honestly, wow. won't ever go back to bubble levels again. i used it to hang curtains near the ceiling. at first, i pulled it out of the box and thought to myself "how do i get this high enough?". initially i tried sticking it to my ladder, but it didn't go high enough for the horizontal laser to line up. then i realized you can freaking tilt this thing and it will auto-level. so you can have it a few feet below the object you're trying to level, aim it, and it will produce lines up near the ceiling. pulled out my bubble level to compare and it was always dead-on. crazy. but really, it's best with a tripod. i have a Smallrig RA-S280, about $60, which i already had lying around and this Bosch uses standard 1/4" tripod thread so it worked. being able to height adjust with the tripod made it far more reliable as if the mounting surface is even slightly wobbly, the laser will be unreliable. i also love the magnetic mount option for added flexibility where a tripod might not fit.

Buen producto, funcional

Nivel Perfecto, funcional y fácil de utilizar

This is a great, reasonably priced laser system. We used this to make sure everything in our new house was level. Bifold doors, baseboard trim, curtain rods. It worked perfect for everything.

The listing photo indicates a case included. This model doesn’t come with a case. Regardless, the device works as expected. Editing after 6 months of use. Changing to 5 stars. I've finished a bathroom tiling project, an accent wall and hung many frames. I'm always impressed with how things turn out. Bang for buck, this is a great product. This is my first self-leveling laser level. Perhaps my comments are universal across the style of level. The pendulum inside is sensitive and takes some time to settle - which is understandable. I wish there was a position lock to eliminate the laser wobble as you move around the room. I attached using the provided mount to a door to get the height I needed in my small bathroom. It was nice to have in that scenario, but I find its use limiting. Making adjustments was easy, finding a mounting point at the same height as my desired location would have involved moving furniture around in other projects. I stick it on the tripod every chances I get.

Excelente herramienta para trabajos interiores o sin mucha luz (el láser color rojo no se aprecia en exteriores) ideal para colocación de muros drywall o pisos de loseta. El soporte también es de buena calidad y mantiene al láser en la posición que se requiere. Lo recomiendo para trabajos ligeros y de bricolage.
