I dropped a mini dse901 the other day. now instead of activating on the draw, you have to blow into the battery, which then activates it for the length of a draw, and then it blinks and goes off. So basically I blow alittle, then draw till it blinks. It still works, it's just such a weird malfunction! Like crashing your car and all the sudden it runs like a penny racer. Anyone know why? or have a similar experience?
