anyone tested this yet? i can't have one sent to me because i'm not in the states, but if they work as advertised then i might try and find a way. I'm getting a bit tired of unplugging the batteries to interchange with that from my second controller battery when the first one runs out. of course if it were easy to unplug i wouldn't care, but they aren't designed to be constantly unplugged all the time.
