I have 3 of these that appear to be doing OK.

Not a ton of run time or cycles on them yet so who knows how they will last long term, but I have a few cycles on them and they appear to be decent. No problems and plenty of power. I do recomend that these are balanced after every cycle as they tend to go slightly out of balance after every run. (Not like my flightpowers that rarly ever go out of balance.) But all in all they seem to be performing OK, just make sure to take care of them by balancing frequently and they should do OK untill you are willing to get something better.
