Here is the thing, I used my powerball without stopping it during 9 hours not only by myself but almost, well and so the problem is that my powerball does now a terrible noise and it's also very vibrating and I can't go now at more than 9000 or so rpm
So I was wondering if what i did (9 hours' use) is considered as a bad use of the powerball and so if i can send it to be repared or replaced (i don't think but i'm asking, we never know) and in the other case what could i do by myself to fix it or something...

Please help...

P.S. : I'm sorry if my english is bad or unperfect (i don't really know) because I'm french so don't blame me for that please than you...
