They appeared in the UK a while back and there was initially a lot of talk but it seems to have become somewhat more quiet recently. They use really fancy packaging (blow alu) and my first concern would be whether the price you see is dictated by the quality of the product or the fact that the packaging costs 3 times as much as an HDPE or PET bottle. All said, there is little doubting that their packaging is some of the best looking out there.
