I contacted the seller regarding this ebay listing. This regulator is for the mini pressurized system. It will not work for paintball or a standard CO2 tank. Also, it uses a European electrical connection. You would need to purchase a step up step down transformer as it is wired for 220V not the standard US 120 volt.
I decided to pass on this due to all the extra purchases and work it would require to make it work in the US.
However after running several searches on the Intense Inc name I think I may have come up with a more direct route to purchase these regulators.
