Bought this thing from fastech. It is supposed to be a mini protank with adjustable air. it is not a bad piece, except that the base does not let the coil make contact with the pin in my battery. it is a 510 post and I tried it with my MVP as well as an old ego battery. nothing. The coil sits way up in the head. It has a pass through pin.. it touches on the top of the head, but the bottom does not go down and make contact on the bottom. any help?
