used it in the pool to take pictures and then when my wife asked, aren't you going to damage your phone, I dunked it into the pool and showed her that it was still working. then ran it under a sink to wash it off afterwards of the nasty pool water. it kept acting like a headphone was plugged in tho, but took a paper towel and cleaned out the headphone jack and it works fine still.
dropped it on the floor a couple of times too from maybe 4 ft high with a gel case on it, and still working like a champ.
