Not Level
The beam is not level. If I mark each edge and the center, then move the beam, it no longer lines up with two of the three marks.

It will help me with the ceiling grid. The tile grid in the bath. The swimming pool and the depth to which I need to dig. With new batteries, the laser is powerful enough to be seen when the cloud cover is light. GREAT TOOL.

I wouldn't hesitate to buy reconditioned again!
I purchase this reconditioned laser level because of the price,features and the reputation that Bosch has. I was not disappointed at all. I used it to install 3 suspended ceilings and this level made it so much easier when working by yourself!

Good product...not right for me....
Bought this laser for electrical light layout. I works perfectly, except the lines are a little to light for high ceilings in bright areas. I had to put it up on a 6' ladder to beam on a 10' ceiling and had to make sure the ambient light was dim. Just too restrictive for my needs. I will have to look at alternatives.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
