I don't use my Aspire Nautilus tanks anymore, one sits at an angle on the battery because the 2 bottom metal portions have slightly pulled apart and I'm just not getting a satisfying vape from them so it's time to pass them along. I use my Aero quite a bit still, I bought it at the same time as the Aspire tanks and it's held up well, basically like new still. After buying a couple Kanger Subtanks (plus version) I've decided to stick with Kanger. The Subtanks are great and as long as you fill them slightly lower than "full" and refill before they're really low they don't leak (at least in my experience). I like them so much I'm buying a couple more and I'm using them more often than my Lemo's. They've been perfect for me but I don't think you could go wrong with the Aero tanks either.
I was on here a few weeks ago looking for a tank,yes I am a noobie ,this fourm turned me on to an E-Leaf M,which i purchased,and believe me I loved it,but ,I kept looking,and low and behold the perfect tank was introduced to me,there is no other tank in my opinion that can compare to the " Kayfun". I got mine on E-bay,A clone,do not let that deter you,without a doubt ,you have never experienced a better tank,and there are a more then one model,I got Kayfun lite,all ..... about no afc,all BS,it is great,I bought two.Just saying.
