Hi all Need to recommend a new tank for my mum. She's been using a Kanger Mini Protank 3 for a while but is always having problems with the coils getting flooded. Looking for: -Mouth to lung tank -Smallish tank diameter -510/Ego fit -Top fill -Drop in coils Only tank I can see is the Aspire Nautilus mini, which is bottom fill and has been out for years..surely there's something newer/better out now? Btw I'm in the UK so it needs to be one I can get here! Cheers!
