yes ive read the manualdid you read the manual?
what makes you think it isn't turning on???
it doesnt actually turn on ....... spins when i press it then does fcuk all no LED flashes or anything, im not doing anything wrong am i?when you turn a reloader on its spins for a few times and the back light blinks slowly and contunually green ...so you know it is on and when it turns red it means low power if my memory serves me well.
try running some paint through it or reballs or anything and see if it feeds as it may be the led not working... OR shout into it as they are noice activatedOR change the battery which you probably have already tried.
