I'm now using vype epen 3 and have been since November. I use 18mg cartridges. I love my epen especially as it doesn't create plumes of silly smoke it's more discreet. I'm annoyed that in the UK the supermarkets that sell your product don't always backfill the 18mg cartridges. These are by far the most popular and it means I have to go trolling around for the right strength. So I'm now signed up to get my cartridges monthly directly from vype yay!
