I have 2 TrueRC 5000 10C sets and my experience has beens similar to Jim's. They have good power and charge fairly evenly. A little more balancing than my FP and TP packs but acceptable. Both got a little puffy after a few flights but have not gotten any more so over the past 2 months. Only time will tell, but they seem like a reasonable value for the money. At the current price, if you get 100 fligths out of each set then they are about the same cost per flight as the more popular brands.
