I thought I'd take a minute to write about my great experiences with the iClear30S tank which fits Ego-style batteries. I've got a bunch of Ego-style batteries.
I was previously using Kanger ProTank Mini and Kanger ProTank II tanks. They were made of glass, which I liked, but they always leaked down into my batteries eventually. I live in a mountainous area, so I don't know if constant elevation changes were a factor. All I know is that my Kanger tanks always leaked down into my Ego-style batteries sooner or later.
Because of my job, I need a tank that can hold a bunch of juice. I travel around to different work sites in various vehicles. I can't be constantly filling a tank or charging batteries. I need a portable unit that will last all day and won't leak, and I need it to be small so I can carry it in my pocket.
The iClear30S tank has been a great success for me. I know it's not "cool" like some of the MODs, but it's extremely functional. The tank is made of plastic, which isn't as cool as glass, but is actually more functional for travelling because it won't break. I don't use any high-citrus juices that might crack it.
I've been using the iClear30S tank, and it never leaks and it never gurgles. I never waste a single drop of juice now. It never leaks down into my Ego-style batteries.
The iClear30S works very well for me, and it has caused me to leave my Kanger tanks behind. I think I paid $15 for it, and I find it to be far superior to Kanger tanks for a travellin' man!
It's not the cool MOD vape set-up, but it's a very functional vape set-up for someone who can't stop to refill juice or charge batteries, and needs portablility, and it's dirt-cheap at around $15. It produces lots of vapor when used with an adjustable-voltage Ego-style battery.
