Took me until now to actually get a pod pack... so none.
20 oz. Pure Energy CO2
Tippmann 11" Barrel
Nothing much... Sharp edges I guess.
These pods are decent. For the 2.50 I got them for they're serving me pretty well. I use the Empire Fast Pack, which they seem to be a little big for. Then again, that harness is on the snug size. The pods are pretty strong and made of a pretty good quality plastic.
Overall, I'd say buy these pods (the 100 round ones). They're pretty good for the 2.50ish you'll spend on them. I would recommend the 100 round ones because if they break, then youll have only lost 100 as compared to 140. I know thats lot, but it could be worse.
