I just got 2 pks of these G5s in the mail today. The first one that I filled (with Johnson Creek Tennessee Cured) leaked just a little to begin with but then stopped (only lost less than a drop of liquid-nuthin' to worry about; loose more than that filling regular cartos). The flavor and vapor was very good. The first and second hits after filling, weren't all that great but after that they were all great. The next one I filled with Coffee from Ms. T's Bakery and it didn't leak at all. So far these G5s are good, if they stay good, I'm gonna use these exclusively (except for when I want some Cinnabomb). One problem though, there's a little bit of liquid in the center tube of the first one that gets in my mouth every once in a while; don't know how that got in there. Well, two problems. The other one is the threaded piece of plastic on the mouth piece. I don't care for that too much; guess I'm gonna have to get somekind of drip tip kind of thing to put over it.
