Just got the Vision Spinner 2 in today. I looked over the paper pamphlet and it didn't mention anything on charging it. So I plugged it up with a standard 420ma usb charger and 500ma wall adapter. It stayed lit a steady blue while the charger itself was red while pulsing green. After about 30 minutes the light went off and the charger turned to a steady lit green. I took it off and put a tank on and started using it. Seems to be working fine but when I press the fire button it lights up "blue" but when reading the manual it states that it should be displaying "white" for 60%-100% remaining, "blue" for 30%-60%, and "orange" for 0%-30%. I just started using it so it hasn't changed colors yet. So does anyone else have a Spinner 2 that could give me some feedback. Starting to think I may have a defective unit...
