I agree with Frank. I bought the Stickman instead of the Stickboy mainly because it had a longer fill hose (48") and the Cascade fill feature which I may or may not use as such in the future. I do have 2 SCBA tanks so it's a pretty good possibility that I will. In the meantime I use that fitting for the female foster while not in use. The quality is superb & I'm happy. It is pricy though. I just got tired of buying cheaper equipment of questionable quality & then having to buy it again or try to fix it. I decided awhile ago to just bite the bullet & get the good stuff first time around even if I have to save the cash a bit longer. There are other options, so do your shopping around before you buy.
