I got this tanks a few months ago and when it first came in the mail, i thought that the package was empty it was so light. I think it is only like 2-1/2 lbs, which compared to my steel before, is much lighter than 4-1/2 lbs. Its so small also. It is almost as small as some other companies 45s. I was very impressed so i aired it up with no leaks or problems whatsoever. When on my gun, because of its size, it made my setup much more compact which i loved. Also because of the weight, i could snap faster also.
I highly recommend it over other tank because of its size and weight. Worth the 180 in my opinion which is a very reasonable price for a carbonfiber tank. If u have the means, get one. 9 cuz nothings perfect
