I have had my vision spinner 2 for a while 6 months probably. It was working great. I fully charged it that night and was able to get a couple of hits out of it, then nothing. I figured it was dead so I put it on the charger. Here's my problem, I screw it in and it blink multicolors (pink,white,purplish) and then it cuts out, comes back on and it's white. I have tried 2diffewnt chargers. The charging led also stays green the whole time. Which it usually changes to red while charging. Please help.
