Bosch Quigo Green Set Korslinjelaser grön laser Räckvidd (max.): 12 m

Excellent quality product - used many times even for paper hanging. You cant always find the right place to attach it where you need one even with the universal clamp. You will need a solid post to attach to - I suggest a photographic tripod which is what I use

The front slide switch or the battery holder is really flaky, I have to tap the thing to get a bright laser most of the time as it keeps fading. Not much fun. Not impressed TBH

Does only what it says - cross line self levelling. It cannot lock and switches off if mounted beyond a few degrees of horizontal. The screw 'tripod' mount is so deeply recessed neither of my tripod mounts work - it is the right thread, just too deeply recessed to allow the tripod screw to reach it. Bit limiting but it is cheap and seems a bit 'one dimensional' compared with competitors

This is so useful, for just about everything you need to get straight on a wall.

Bought this to help with building fully fitted made-to-measure wardrobes after carpenter let me down. Works well, although getting/keeping it in position across any meaningful distance is "tricky". Is better for closer/smaller jobs, but that said, the wardrobes are built and are perfectly square/vertical, which would not have been possible without this kit.
