    Charges fast but charge doesn't last real long. Doesn't come with tank. Otherwise I like it! Small, fits in pocket easily

    Good Little Mod

    The eleaf istick 40w is fairly easy to use and the battery life is great for its small size. It fires up my atty right away, can lock the coil resistance, and change settings quickly.

    Only cons I'd have with this mod is it does not support SS coils for TC mode, the TI coil recognition is a hidden feature you have to search online to find out how to access, and you can't change to preset 40w in TC mode. If it supported SS coils, I'd up the rating.
