Not at all durable. After a few months, the batteries didn't make good contact and I constantly had to take them out and put them back in. It didn't measure at all accurately in outdoor time.

Terrible... It's the third one. The first one was stolen at work, the second one broke, and since I didn't want to spend another 150 euros on a Bosch, I decided to get something cheaper because I thought it would do the same job... Wrong, let me start. The battery compartment is problematic, the batteries don't make good contact. As soon as I tried adjusting the springs to make the batteries touch, they would immediately pop out, so I would use aluminum foil. And finally, I found springs from one of my son's toys and replaced them. Sometimes it turns on and then the laser stays on without any indication on the screen, and you have to remove the batteries to turn it off. The "buttons" - what buttons? The membrane that you press is torn. When there's strong light during the day, you can't see it, it's not accurate and it's difficult to use. And lastly, it measures about 2mm higher than it should, but that's the least of its problems. When I realized this, I would subtract 2mm and it was fine. This tool is not worth what you pay for it, I'm going for another one..
