Got two bottles a Messer pub bottle and a older small sealey refillable it looks more like a tall soda stream bottle than the current one as mine is grew with just a small screw thread valve
anywhere I can get them refilled locally, though I dont have a reg yet for the little one I'll use the big bottle for home and the little one for out and about
