This E-Cig that I have is the Vype E-Pen and on the whole it's a great bit of kit, the battery life is good so no need to charge constantly and the flavours of the cartridges are really nice. If I was to be a little picky it's that I found the strongest available cartridge to still be quiet mild for my liking so I mostly use it as a backup for my other E-Cig when I'm on my travels. But hey all in all it's very good. I do hope that in the future more flavours and strengths will be available.
