Smaller than it looks in the videos/previews which is great as it is a pod mod. Fantastic quality and finish on the gunmetal version I recieved, Finish is more matte than the pictures which I don't mind at all, but the device itself is very sturdy and weighted, coupled with the PCTG tank and feels great to hold. Menu system very easy to operate and old school style and simple which I like a lot. You can get a very tight MTL from this (even on 0.7ohm coil) which is my preferred style of vaping, so am very pleased with that. Lastly it is compatible with the Nautilus BVC coil range as well as some other brands out there which have the BVC coil design also. You can get the XP version of the pod which will allow you to use bigger coils (Lower resistance) if you like; so good for restricted direct lung and lower milligram juices.
