I got my Rocket V2 rba from fasttech on Friday. The first RBA that I purchased was the Rocket V1 at the beginning of January. Still relatively new to this. It was cheaply made and it was always leaking from somewhere. All the same, it produced a wonderful vape. I always think of latte bubbles whenever I vape it. When the V2 came out, I ordered it immediately even though it was relatively expensive for a fasttech item (was 24.72 when I ordered it but it has dropped to 17.51 since). The design, other than the AFC, is the same as before but all the parts are now in stainless steel. It comes with both a polycarbonate and a stainless steel center section. I put it together with AW30 6 wraps on a 1.4mm screwdriver (1/16"). Came out to 1.8ohm. I used cotton to wick it leaving a little extra to push down to the bottom of the base. The AFC is a ring with 2 holes in it. The holes are different sizes. There are 2 corresponding holes in the base. It is extremely easy to tailor the draw. Opening both holes produces a very airy draw. I ended up only opening the smaller of the two holes and it is perfect for me. One of the best parts is how easy it is to fill. I closed the AFC, popped the top off, filled it to the top, put the top back on and reset the AFC ring. No leaks no fuss!!! I am using it on my MVP2 and it vapes wonderfully. Great vaper and great taste. I highly recommend it. By the way, I was concerned with leaking so I left it on its side all night wrapped in a paper towel. No leaks at all.
