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

This laser level is awesome!I purchased this to help install a TV Mount and some overhead storage racks in the garage it has 1/4-20 camera tripod threads for attachment to a tripod for shooting the laser cross hairs vertically for overhead work.Bosch is a name brand that for me has shown usefulness and quality in the products I have purchased from them.

Works great. My son had bought a cheaper one and it did not lock in as good. The likes were not study. This one lines up good and stays in place.

Bueno... solo que siempre es Cruz... en la actualidad tienen cruz, línea horizontal, línea vertical... según lo necesites... pero ayuda... por el precio, no puedo exigir tanto.

It works really well. Swivel, magnet, stability, all is great

The product was exactly as described. I would like to change the batteries for a rechargeable ones.

I tend to put a lot of effort into trying to get shelves, pictures, and other household projects to be level, so I use laser levels quite a bit. This Bosch unit is nice in that it has a nice clear beam even in daylight. It is also a step up from cheaper units I've used in that it projects a cross pattern for aligning both in vertical and horizontal axes. For example, I mounted a column of shelves on the left side of a wall and wanted another column on the right side. Very easy with this level as I could adjust the vertical line to where I wanted the shelves to be on the right and then I adjusted the cross-hair from a horizontal aspect to line up with the shelves on the left. Easy.You'll likely find that using a tripod is the easiest way to mount this unit for use, though it does come with a handy clip attachment if there is something stationary nearby that it can be mounted to. The clip can be easily removed when not needed.There does seem to be one flaw however. When the device is within 4 degrees of level it uses an internal pendulum to auto-level itself, which is great. Most of the time this is the way to use it. When it is rotated more than 4 degrees, the beam stays on so that you can self-align for more diagonal oriented angles. Again, nice. However if you want to self-align with the laser but want to use it still within 4 degrees of level, there is no way to disengage the auto-leveling feature and just leave the laser on. There are times when I want to use the laser for a straight/perpendicular line but don't necessarily want it to be level with the horizon. There doesn't seem to be a way other than being at an angle greater than 4 degrees. It seems like it would have been easy to disengage the pendulum (which happens when you shut off the laser anyway) but leave the laser on for use.Not something I thought of before I purchased it. Maybe those more handy than me would find this to be obvious or maybe suggest this isn't the right tool for this kind of job but I'm just an amateur when it comes to home projects and spending quite a bit more for a level than I had to, I see this as a downside of using the item.

Excelente producto cumple lo que indica ya lo he usado varias veces y trabaja sin problemas

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.
