I got a twin pair starter kit of the Ego-T a little over a month ago. I am interested in upgrading them and now waiting on a 1000mah VV battery I ordered from Apollo, pretty clueless as to what can be done worth wile to upgrade the Atomizer though, any suggestions would be great. I think I need to give my atomizers a good cleaning at this point or perhaps they are just finally starting to wear out. I don't mind spending a bit of money on this for something that works good and has a good life span.
