Let me start by saying i wasnt sure when i ordered this. Bought this from a local vendor in Ireland call E-smoke Now i am speechless this beats all top market sellers protanks, Evod etc with hands behind its back... The flavour is amazing and constant vapour is clouds vaping 2 weeks and not a dip in flavour... Absolutely no gurgling no leaks no burnt or dry hits this is a super tank im amazed i think alot of my clearos tanks etc will be made redundant one very very very happy vaper i highly recommend this tank to anybody into clearomizers / Glassomizers only down fall its not rebuildable benefits pyrex tank and fully cleanable
