What owners single out
In their words
“One of the first items I bought when starting our renovations at home and has proven to be one of the handiest. The 1/4" female thread is a good feature for mounting - I mounted it to a quick release plate for use with my camera tripod. Have used this for literally everything from the ground up - Levelled out the yard, concrete formwork, Re-levelled the house (post & beam style foundations), deck ”

“This Bosch laser level is the worst purchase I've ever made at HD. It flashes constantly, no matter where or how it's placed. Fresh batteries don't help, Bosch should recall this item due to the high stress/frustration experienced while using it!!! Someone, somewhere, will have a stroke trying to hang a picture with this thing!”
