PMI Pure Energy CO² Tank

[Misfits]

Hi Guys! I´d like to know somethings about the Pure Energy CO² tanks:

1-What´s the difference between this tanks and the standard tanks sold everywhere?
2-Are the Pure Energy CO² tanks anti-siphon?
3-Should I buy a 20 Oz Pure Energy Tank, with or without the ON/OFF adapter?

Thanks for answering!

The PE tank has a pretty ****** looking logo on it. Other than that, nothing is different.

i have one and there is nothing special about it,but the paintball store nearby has ant-siphon on the 20oz tanks,they might come that way
