This mod looks excellent, better than it already does in the pictures. Its compact and fits nice in your hand. Imo, having resistance around .20ish at 65/75w is best suited for this single 21700 mod (if you're like me) who wants consistent and hard hits/ramp ups for longer without requiring the bulk of dual battery mods. Would recommend this to anyone who likes a dainty or wants a more portable mod for on the go. Only drawback is the battery door may wear out after awhile, hence the four stars.
