Really good so far, this is the only E-pen I've tried and actually bought refills for. Doesn't leak in your mouth like some other brands.....! Little bit pricey, and the environmental footprint is a bit of a concern....if Vype could offer some kind of recycling program for the used pods that would be pretty good. I'm looking forward to trying the nicotine salts "pro" versions - but so far the mint one is pretty good and the cherry isn't bad, the regular tobacco flavour is pretty good as well.
