Compact, nice feel in the hand, houses up to 30mm though 28mm ideal. Dual 21700 all day and next day vaping and beyond depending what tank or rda you put on top of it. No issues with battery door since started using it and fast delivery from ecigone. Blue matches most of my blue tanks nicely too.
This is a great for a dual 21700 mod it's smaller than some of my dual 18650 mods. There was a problem with my order ecigone rang me explained there'd be a delay of a day or 2 and would throw in some free juice as compensation. Great customer service.
Extreamly good mod.
Seen these on offer at Ecigone and snapped one up. Top quality device, dual 21700 and smaller than most dual 18650 mods.
