I've had two (no make that 3 if you count one of Ed's) Vision spinners go bad after the first charge lately.
check out the marks of a genuine Vision Spinner (two of mine were fakes, and the whole eBay rating system is a farce, one I just left bad feedback and he credited my paypal so that got rid of the bad "fake crap" feedback, so I just wonder how many do that now? argh!
I've got one 1600mah green one that's received a first charge successfully it doesn't blink though while charging.(it does at first but then that's it)
