Title: Works great- not pro grade
Review: I've owned 4 of these angle finders. Unfortunately that the problem. I've had to buy 4 of these because they self destruct after about a year of use. The last one was replaced by Bosch and the replacement broke 3 months later. This all stems from a spinning gyroscope in the apex of the gauge. Even slight concussions can interrupt this. It also appears from careful examination of the broken protractors that they use sub standard glues to hold the moving parts in place. This may mean that the device cannot handle high temperatures. Which happens when you leave it in a work box or truck. I keep buying them because they work great and I can't fabricate metal without them, but this is is not a durable product.
