haven't had reg problems like others say
scratches a little easily though
Ther is not much to say. Great tank, very consistent, very light. If you were thinking of getting a 68 45 tank, get this instead. It is lighter than the crossfire tanks, i have tested it. Only problem is that there is no burst disc for the fill nipple cover.
Ill give it a nine because it scratches easily. A must buy for anyone wanting N2!
