It's early days, I have only been using Vype for 10 days. At present, I am pleased with the Vype pen,and the choice of flavours available.
The instructions are easy to follow,and the pen operates well. I hope to try more flavours. The whole system,i.e charging and fitting the cartridges, is straight forward. I ordered on line new cartidges, and they arrived quickly.
I hope these standards continue.
