i think they are good enough. they are cheap enough not to be too worried about exact specs but perform high enough to satisfy us, im sure the higher priced neu packs will be better but for me, the zippies do it. on the other hand, im looking for some smaller 4s packs (true 25 or 30C) so i can reduce weight. any ideas?
