For a little while now I've noticed that manufacturers are producing Rebuildable tanks bigger than 22mm as the norm. I understand that it enables vapers to build bigger coils, more juice capacity and use these wires that involve incredible descriptions but personally I'm happy with 22mm as they fit on my mods comfortably. Seeing as most (if not all ) of the current releases are topfill I'm even happy with the likes of the Serpent mini as it offers pocket friendly daily use and magnificent flavour. I'll admit it's actually done me a favour because as soon as I see 24mm or whatever I immediately don't bother looking into it any further. Each to their own and again manufacturers are never going to please everybody but I was just wondering what others thought?
