We got this Soda from my parents at Christmas and I can no longer do without him now. The quality of drinking water is indeed in most places in Germany fortunately very well (here in Berlin is also not chlorinated) and the bubbled water tastes better than bottled water bought me. I especially appreciate that the bottles are made of glass, so you can clean in the dishwasher and neither the taste of water or health be affected by plasticizer in plastic simply. Due to the fact that the CO² here comes only from the top of the bottle and not get into the water through the soil like plastic bottles, glass bottles are slightly smaller. I suppose but for better taste and hygiene gladly accept, you can indeed set several bottles (which, incidentally, also have no expiration date as the plastic bottles). In addition, the glass bottles are very decorative. All in all a round, healthy thing, with which you can save a lot of money and effort.
