Any feed back on Acecare carbon fiber bottle

Agreed. I have a 2 year old Acecare 6.8L. It’s been a great tank, valves not great but functions. It just has a kind of sticky/gritty clunky feel to it. A bit difficult to smoothly slow fill a gun. 

I shoot with a friend that has an omega tank and damn the valve is nice and smooth. I replaced the fill adapter on mine with a StikBoy from Air Tanks Plus. Much nicer than the stock one.

My tank was something like $225 delivered and the fill adapter $145. If you’ve got your own fill source there hard to beat

I bought an Acecare DOT 9L bottle (only) from Amazon for $450 to the door. Added a Jubilee valve from Best Fittings for $100 that had a Wika gauge, and it's a great setup for $550. I only saved $1-150 from what other tanks were going for at the time, but I got the valve and gauges I wanted. The real savings on the tanks is with the non DOT rated version, but you need a compressor. At the time I didn't have one, and I wanted a travel tank that I could fill at a shop if I was on the road. There are additional savings to be had ordering direct from China or through E-bay, but I wanted Amazon backing the tank and pushing the pace on delivery. A quality valve is important to me and the Acecare valves are not that. Overall, I am very happy with this tank set up, and I used the savings for important stuff like whiskey and pellets.
