I got my tank a few weeks ago and I must say I love it, its soo tight and compact. Poeple think its a smaller tank, but I can shoot over 1000 shots out of a full 4500 fill. Problems with the fill nipple began the weekend after I got the tank, it started leaking out after the 3rd fill. I figured it was just a freak occurence until the next weekend when it happened again, both times I was able to correct it. well this past weekend it would NOT fill. I took it in to get fixed and it appears that an O-ring inside the fill nipple somehow lodged itself over the opening and thus. NO Fill.
A friend of mine who got the same tank a few days previous has had a few fill nipple problems too so I am figuring that either they missed a few crappy ones, or the ones they supply with the tank are just crap. I can fix it by buying a new fill nipple, but hell thats an extra 30$ (CDN) I don't need to spend especuially when I dropped 400(CDN) on the tank.
Conclusion:
Overall great tank, dye makes good stuff, hence why I bought it. Just wish they had better components on this one. I gave it an 8 because of the nipple probs. Otherwise it would have gotten a 10
