It was auto firing and acting real weird for like a half hour after I dropped it. Autofiring, auto-clicking the +/- buttons, together and one at a time and eventually turned itself off and hasn't turned back on since. The battery shell has a nice sized ding on one of the front corners more in the middle of the battery. The guy at the shop I bought it from told me I have a 30 replacement warranty, would I be able to take it back to them to be replaced or am I screwed?
