I had an ac9 and traded it away for a used ody. wasn't impressed, very airy draw! even for a genesis and the center post is hard to deal with. Pain in the ... at first. other than that it was good. not worth $140 for the kit, imho, there are too many cheaper alternatives that vape equally as well, if not better. Personally I prefer the PMMA tank over SS, but it doesn't seems to make much difference flavor-wise. It is made in the usa, and that goes a long way for me.
Rip is now offering a new cap with a smaller air hole.
