People complaine that this tank leak leak and blow burst disk but since I had this tank I never blew a burst disk or had a leak. But for the price 130$ Canadian I found that it was at a bargain. Also noticed that I had a tighter shot grouping using compresed air, this is because of the regulator this is on the valve on the tank so you have better fps consistency. I mentioned that this thing is some what heavy but not that much I would say its about the same weight as a filled 20oz tank filled.
If your looking at trying out HPA and dont want to pay 300$+ for a 61ci/3000psi go with the 47ci you want regret it.
