I started with the Vype e-stick and love the design of it and the ease of use. The only problem is that it only comes with one strength of nicotine and it's too strong for me so I had to get the e-pen. It's a nice design but you have to hook it up to the charging cable and it is a bit big for me. I like the different flavours and the fact that you can get different strengths of nicotine caps. It's easy to use, just put a cap in and you're ready to go. The service from Vype is fantastic. I had my e-pen within 2 days of ordering using standard delivery and they keep you informed from ordering to dispatch. The only thing Vype could do to make me like them more would be to bring out lower strength tips for the e-stick as I much prefer the design and ease of use of the e-stick.
