Picked up a new "tank" last night, and thought I'd share. My old one, when I bought it, was told it was serviceable; i.e., I could take it apart, clean it, replace the coil, etc. Well, it started not smoking as well, small hits and tasting burnt, so I tried taking it apart. No luck. Frustrated, I went to a new smoke shop in town that specializes in just vapeing equipment. After learning a lot of good info, I settled on purchasing a new tank. This one is fully serviceable. I can take every piece apart, clean it, replace the coil, etc. Best part is, I could still use my old battery which turned out to be a decent battery. The new one I got is made by Kangertech and and it's called the Genitank Mini. It's a dual coil design so smoke is much smoother and more of it. It's also got adjustable air intake so I can dial it down small puffs, or open it up for big ol smoke clouds. Hope you guys enjoy!
