I think the bottom line is if you can
afford it, it is a worth while addition to your kit. What I have seen,and experienced myself is after the initial WOW factor of vaping, you will come across times when things seem to go a little flat, you need just a little more of something.. what that something is, is difficult to pinpoint, but many here experience it from time to time, sometimes it manifests itself as flavour desertion or no throat hit or poor vapour production or a combination of all these things.
Over the last 3 years vaping has come a long way, initially there was little choice in kit, there was one type of atomiser, very few flavours, what there was available was expensive, and costly if you did not like the flavour or strength you were kind of stuck.
Now having all the choice of different atomisers, flavours and also the ability to alter the voltage means you should never need to be stuck in a rut, all these things give your taste buds a brilliant work out and help to keep vaping a fantastic pleasure
