I bought 6 Zippy compacts before I saw this thread. However, I must be the exception becuase I have had very little trouble with Zippy's over the years. I always break them in with 5 easy flights, never drawing more than 1200mah. I charge at 1C or even .75C if I'm not in a hurry(hotel room). And I very seldom draw more than 3600 out of a 5000 pack.

Just today I was flying a Zippy and the power seemed down. When I landed, the pack had 96 flights on it. All in all a good value.
