ive got the A7 on my VMod 2.0 bottom feeder. so far i like it. theres a minor cosmetic issue to remedy, but all in all its performing great. i forgot to wash it before i started vaping it, but i must have gotten lucky because theres no machine oil on/in mine. not that i know of anyway. also, the stock wick and coil seem to be fine on mine. but i should add that i am not a pro coil wrapper (yet

) so you guys might have a different opinion regarding the stock coil if you are a pro.
