Following this thread made me unnecessarily paranoid enough to buy some mega attys and carts. I almost hope I end up using them.
Leaks: Not all leaks have anything to do with the atty or wick. One of my friends tank started leaking yesterday. One of mine started leaking today. - My buddy was outdoors working when our Canadian neighbors decided to send us low pressure and cold air (temperature dropped from 28 above to 9 below in about two hours). - That tank is not leaking today. - Mine is a little different story. I couldn't figure out what happened for a while.
I needed both my hands for a few minutes this morning and so I put the whistle tip between my teeth and bit down hard enough to not drop my ego while I worked. It changed the shape of the tank slightly and now it doesn't fit quite as well. It spins in the atty cone easier and just doesn't quite seat as well as it did. Popped in a fresh tank and it doesn't leak.
Too tight a draw: I grabbed a fresh ego battery that I hadn't used before and went out yesterday evening. At some point, I noticed the draw was really tight and I thought my atty was starting to plug up. - That wasn't it. It was the difference in threads. The atty snugged down tighter on that battery than it did on the other two I've been using and didn't let as much air come in the notches on the bottom of the cone.
Muted Flavors: I didn't experience this until today. Some of my flavors have certainly tasted different in the tank system than they did from carts, but I hadn't noticed a *lack* of flavor. I've been blowing my atty out between tanks and changing flavors pretty often. I've only used two flavors today and yesterday and I didn't blow out the atty between tanks. So, I went maybe 6 tanks without blowing out the atty. - No flavor. - I blew out the atty and gave it two or three quick dry fires and the flavor is back. - The design of these attys allows a lot of
juice to exist in them. When I blow them out, quite a lot comes out. For me, it seems to be a matter of not allowing different flavors to mix in the atty and making sure to blow it out after each tank (or maybe 2 tanks if I didn't change flavors).
I hope that helps a few people. I've had very little trouble with my ego-t. Some of the problems mentioned in this thread could have convinced me not to buy it had I read all that before I already owned it. - Some folks really make it sound like this system is completely flawed. Mine isn't. Mine works great. - It may be that some attys are problematic and it may be that some of the leaks etc are caused by such problematic attys... but not every problem with such symptoms is a bad atty or some inherent flaw in the design.
