I am relatively new to vaping(about a month in) and I just got my Ego-t today. I started on a KR808D-1 and it was ok, but the ego-t is the bomb(IMO for what its worth). I just wish I would have started with it to begin with. It is a lot simpler to use as far as filling tank as apposed to cartomizers. The vapor production is great and I find the flavor to be cleaner(for lack of a better term). There isn't as much of a throat hit which is ok with me because I don't care for a big throat hit(it could also be the juice that I'm vaping). I have been switching off between vaping about four different flavors since I got it this afternoon. They are all from juicy vapor, Wicked Sick Menthol, Doc Pepper, Mt. Dew, and Mint Chocolate Chip. All of them are the reduced PG (although I am not sure of the exact mix). All four flavors I highly recommend(have also tried Ecto Plasma and Bubble Gum, also very good). Switching flavors on the same atty has not been a problem. The flavors seem to intermingle four just a couple of hits and then it is a pretty clean taste. The ego-t seems to be a very well built product and I can honestly say that I am completely satisfied with my purchase. I bought the kit from Cignot on Tuesday and had it in hand by 3:00 on thursday. I am so happy right now.
