I don't mind the current bottles, had a few(of the tops) crack on me, but i keep a few leftover empties as spares now(soak, wipe and dry). Pretty much the only bottles i don't like are the letterbox friendly square things, perfectly functional all the same, but eh...(they come off as making the product feel cheap - functionally they're great). Not adverse to glass and dripper, ie. dinner lady style, but that's gotta move through the postal system(glass breaks easier from getting knocked around) and would naturally require pushing your prices up, it's a nice touch but not a direction i'd like to see you go personally(fancy bottles are nicer, but it's still ultimately going in the bin most of the time). If you gotta make a change due to QC issues or whatever with the bottles, have at it mate, but i'm personally happy with the current ones(not perfect, but nothing is).
