  • Great product, easily visible and quick to level.
Excellent laser, good price. I like the dots instead of lines that other laser levels project for lining things up on the ceiling based on marks on the floor. Seems very accurate to me. Laser is easily visible in daylight (although I'm working inside and not in direct sunlight). Good attachment options, easy to use. ... show more

  • Indispensable tool
I've been a General Contractor for many years. My focus is structural framing. I've used 8ft levels for years to plumb walls as has my crew. I've used various other laser levels for other tasks successfully, mostly for foundations, grading, etc. I've also used previous "plumb levels" with limited success. This one is a game changer. Very accurate. Very compact. Very effective. All my framers use this now. Excellent tool. Just wish it had a charging option instead of replacing the AA batteries. We just keep spares in the case. Worth every penny. ... show more

  • Sturdy accurate laser
It’s been holding up well to constant abuse, arena rigging. It’s been knocked over frequently, bumped, kicked, covered in chalk, and it’s still bright and accurate. Much more affordable, and compact than “the other go to brand” No complaints yet.

Great product you need this when you work at the field you can see your line not like other products

  • alright
works alright but it would help if the points could be turned on separately instead of all directions at once

  • Green laser is easy to see.
Works great. Good to use and check floor high spots as well.

  • Works great and is durable.
Bosch makes great products and this laser works great and is durable. I should have gotten a self-leveling alignment laser years ago. The range of the laser in the product description is accurate, but the range is adequate for the typical handyman.

The media could not be loaded. Es una marca Bosch recomendable con garantía, láser de alineación autonivelante.
