I have had my powerball since October '04 and it has always run smoothly with no problems but I have recently noticed the LEDs do not always emit light- even at well over 10000 RPM!
I found that the light increases normally up until what I guess to be roughly 5500 RPM and then they just suddenly turn off and then when I decrease the speed to below this value they turn back on. I could make a short video to explain how this happens if I needed to.
Has anyone else had this problem before?
