Got my first Kayfun style tank on the way. It's the hcigar version. Anyone know if that's a good one? Also have a glass tank for it coming. I need to see liquid levels, and I've had some bad experience with plastic. One more item interested me during shopping. The Hcigar 3D. Has anyone here tried it? Does it work well, and does it leak? I love my Kracken, but it's not really commute worthy, so I've been looking at leak free options....
