These really cannot be compared to air tanks.They are much more like co2 tanks converted....I wonder????? Anyway bought a tank,waited a couple weeks to receive it, I was about to file a complaint to e-bay. Finally it came. It is the exact weight as a 20 oz. co2 tank. Never paid attention to the hydro date on it whether it was current or not.Seemed to be new.
Quality- poor. Came to me with the gauge up-side-down. After 3 uses the O-ring between the bottle and the regulator blew out. Now I must fix that. What next? granted these are not major things, but it is something you would never see from another manufacture company. Boils down to poor Quality control.
1 last thing,This is a 47 ci 3000 psi tank, it will get 300-600 shots per use.Barely enough for 1 game-1 hopper 1 pod. now a 20 oz. co2 tank which is the same size and weight will last you almost all day. Co2 is much cheaper and almost trouble free -compared to these tanks! I'm actually leaning towards the 20 oz co2 tank. No actually I went out and bought a decent air tank. with no issues. I did learn a lesson- If it seems tooo good to be true(like a cheap tank) It probably is. I guess I'll revise this as more problems occur. And I'm sure they will.
do not buy this product unless it is under $40 with shipping included. Yes I rated it a 1 because from all the tanks I know of and have heard of these are the worst.
