Nothing is wrong with an ego set up! I have just spent the entire day researching the provari, REO and the iTaste. I really don't have the $ for the provari or REO at this time and might go with the iTaste to use at home. After all day on this forum and internet, my head is spinning with rewicking, recoiling, etc. I like being able to put in a new coil and vaping away! I guess I could save money if I would learn to do those things, but I think for now, I'm happy saving what I do by not smoking! Maybe a mod is in my future someday, but right now I am doing fine with my egos! Besides I have 10 ego batteries and 15 tanks! Every time one of my friends buys a mod, they give me their old ego related equipment! Enjoy your egos and no matter what your vaping journey brings, stay smoke Free!
