Would have given it 5 stars if the batteries included weren't leaking!

There are cheaper laser levels/stud finders but none better. I just bought a second one but the first is 12 years old and still works perfectly.

I've had this auto laser level for 15 years. It's traveled with me to 3 different continents and it's been worth every penny. The only reason I need a new one is because it finally died

Not too bad for an inexpensive laser level/stud finder combo. Both functions seem to work, including the auto-leveling, so the innards are OK. But the body looks and feels cheaply constructed and the attachable mounting cone (and instruction sheet) is confounding and also cheap. I will probably blue-tape it to the wall and be done. Mine had a yellow "2 tools in 1" sticker attached to the bottom, that when removed took of the "Detector Zone" label that was painted on. Also inconvenient that you have to keep pressing on the stud finder button while using it, a slow process. I will tape it down next time.
