This tank provides reliable air flow to my marker. To date, I have had no problems with this product. I notice a great deal of complaining about customer service. I can't speak to that end, but my tank works.
I eventually bought a scuba tank which can only hold 3000psi. So, I regret spending the money for the 4500 tank when I will never fill it that high (that's ok... the local pro shops can't get it to 4500 anyway). However, that isn't the tank's fault. There is nothing wrong with it.
A lot of people look at aci products with the same kind of distain that they view Brass Eagle's stuff. I atribute this to the fact that aci makes a line of budget markers and thus, they bear the reputation of a "cheap stuff" company. I have three aci products including this tank, a barrel, and my scuba fill station. All three perform exactly as advertised, and the price was fair. People just need to free themselves of the notion that brand name and high price always equalls quality. I mean really... if the DYE Boomstick was a $35 barrel, would it still be one of the "finest in the world"? Would anyone buy it? Or, would they opt for something more expensive thinking that it must be better because it costs more?
