I just started usimg cartos and two weeks ago i didnt get it either. The only teason i did was really baditude, my second day on this forum he suggested them, even suggested the mvp and let me tell you it took me $900 and a dozen wick tanks to go a duh maybe ill atleast try it! And honestly the only reason i did try it was because i had credit at a store. So i splirged and tried one.
Get urself a smok dct pyrex and try it out. I love that theres not a bunch of crap to fiddle with, wicks are messy when cleaning and changing and you have to wash them and they burn real easy. And by burn i mean burnt.
There is a big break in Time with wicks, i have to vape atleast half a tank woth wicks just to start to get good vapor.
Cartos are clean easy, even easier to fill than wick tanks. U easily see your juice level. Ive yet to get a burnt or dry hit. Yeah and no break in time. None. When vapor starts to get low its time to refill or switch flavors. There is no soaking in vodka to get rid of any production waste that lingers, and the smoke pyrex dct and the ibtanks are glass. No need to ever worry about cracking or melting plastic. No leaks. No more qtips and cotton balls to dry off my battery connections.
The day after i got my smok dct, i ordered an ibtank, 3 more 6 ml smok tanks and then i went to fastech and ordered 4 of the 3ml smoke pyrex tanks. Just placed an order at ikenvape for 15 punched cartos in two different sizes.
Let me tell ya that the 6ml tanks are awesome for not having to refill. The fasttech 3 ml tanks are less than $6 and i found the smoke pyrex 6 ml for less than $7
Cartos cost about the same as wicks, last the same amount of fills, only you dont even clean them. I have unpunched cartos for taste testing new juices.
Fyi my other tank experiences include
Kanger t2 t3s t4 evod esmart510
Vivi nova, mini vivi nova,
Stardust, iclear16, itaste10s,
Aspire bdc ego, 510 and mini nova,
Thats over a dozen right there.
I have a iclear 30 but dont feel like soaking it and breaking it in.
I have 5 unused iclear16s they had been my go to tank so i bought extras. They are clean and unused.
