I wish I could give the Dot Aio V2 device 6 stars. Overall flavour production is unmatched. The above bar quality you get from these devices is really impressive; with a wide variety of interchangeable coils and pods, this product hits all marks for me. I love how customizable it is, down to the LCD display or being able to change the tank and battery doors to different colours! As well as being able to vape freebase or salt nicotine. It's hard to find a device with this much versatility, I love it.
