I’m really impressed with this new Dotmod Dotbox. I was looking for a dual 18659 mod that was small, light and would match my gold atomisers. This fits the bill perfectly. It is a perfect match for the Petrie 24 or any atomiser up to 25mm (26mm might show a slight overhang). The chip seems really good and the menu system is simple and intuitive. I found that resistance measurement may read slightly under but other than that the temp control on SS316 was fine. Fit and finish is excellent although I have found that the battery door does not close completely flush with the case with some batteries that have a thicker wrap (the machined tolerances are really fine). The removable front door is a bit of a gimmick but it does help to hide the USBc port rather cleverly and provide some hidden pre-set buttons. Overall I think this is a first class mod at a fantastic price.
