I bought the Fusion 2 and two 88 gram cartridges.
Shot several different brand and weight pellets through it. Then I couldn't get any more CO2 because of the coronavirus crap so then I looked at my pile of extra paintball stuff I came up with this. It works alot better much more consistent and I don't have to worry about the temperature. Now that the regulator has settled in I'm getting 134 shots per fill 3000psi down to 1100psi reg set at 910psi shooting JSB 8.44gr at 697 fps low to 702 fps high through the whole shot string. Very accurate 3/8 in at 30 yards. Very happy with it.
