I run in to the occasional person who LOVES the ego-T or ego-C tank system, but they are in the minority. For most people they are a nightmare of leaks and bad performance. I was talking to one of the guys up at the local brick and mortar store here in town and he said pretty much the same thing, out of every seven to ten that he sells, one person just thinks they are the best thing ever, and every other person hates them. It's so bad that he warns people away from them, and then only sells them if they understand all the potential downsides and that he won't be taking them back, and they take most things back. This from a man who sells a lot of joye equipment. They carry the full line, but they are talking about only keeping the upgrades on hand and not even selling any of the tank kits anymore. I have never had one perform well or fail to leak juice all over me, or in my mouth. I guess they just line up perfectly with the way a certain minority use their vaporizers and for them work phenomenally, but for the majority it's just not the case. I hate to think of someone in that majority ordering their very first PV with either of those tank systems, experiencing all the problems that so many people experience, then chucking the whole thing in a drawer and calling it a failed experiment. I think anyone interested in them should try them, but be prepared for disappointment, and in the case of a new vaper make sure you have an alternative plan even if it's just a few regular cartos to hold you over until your emergency order of something else comes in.
