Protank or evod head will NOT fit on the x10's ordered from fast tech. The air hole inside the tank itself is slightly smaller diameter. Also, the atomizer hole diameter is a bit smaller as well. The x10's work well, but are not compatible with anything else. Same thing with a protank type clone ordered from fast tech. Hopefully this makes sense.
Basically the tank airhole diameter is smaller than the diameter of real protank, evod heads. The atty heads will screw into the bottom plate but because of the size discrepancy, they won't go in. Booooo.
