I just dropped mine over the deck, about 15 feet to pavement below. Went down, picked it up, and still working like new. I do have a slight problem with it, the vibrate doesn't always work.. cuts in and out. I'd rather use just the vibrate as the beep annoys me, but I have to keep the beep on. Mine also have some cracking up towards the threaded end. Just on the surface (although after the drop, a few went deeper). Maybe I just got a wonky one, but still can't beat the performance and price.
