Needed a glass tank for my menthol and mint juices, and I finally hit the jackpot. Yes it only holds 1.8 ml of juice, but I like how it fits my EGO twist perfectly, not obnoxious looking. They have a larger version, Aspire Vivi Nova-S BDC Clearomizer (Pyrex), that holds 3.5 ml for those who want a bigger tank. Also tried the Kanker Protanks, including the mini, and was not impressed. I do love the Kanger T2's though for my non mint juices, plus they are cheap.
