The SodaStream has dominated the DIY water carbonation market. They work pretty good, are priced fairly, and make loud embarrassing noises when in use. The perfect addition to any party I suppose. All fine and dandy for the masses, but what if you want something a bit fancier. A bit quieter.
Check out the AARKE Premium Carbonator ($169). It is shiny stainless steel (or matte black), has 3 independent safety valves, and includes a nontoxic PET bottle. If nothing else, it looks cool and it is considerably quieter than the SodaStream.
