Good: 1) It's cheap, got a preset 68/4500psi for $150 on ebay
2) 4500psi is always nice!!! 50%% more shots than an 3000psi
3) I like screw in tanks that you can use with almost every drop forward out there especially Pyscho Ballastics' DF's
not much else
Bad: 1) Preset tanks are set to 500psi despite what 32* degrees says(625-725psi, and I just love that 100psi variance they threw me, like they had no idea what the hell they were doing when they made this tank) that means all guns that normally run on CO2 like Spyders and Tipps are SOL when trying to use this tank, you just won't get the velocity oh yeah, I'm talking about the 68ci version
2) That preset regulator really sucks, it's inconsistent as heck, the HPR on my Timmy varies from 250psi to 300psi on every shot, I gotta ditch this tank.
3) the gauge sucks on it, cheap plastic, will break on you, I've replaced it twice until I bought a Dye gauge
Don't get this tank unless you are desperate for a low pressure sucky Nitro tank. I haven't seen a worse tank out there. When buying a Nitro tank, it's WORTH spending the extra money to get one of the big boys with reliable regulators otherwise you might as well stick with CO2, as long as you have a Palmer Stabalizer.
