SodaStream MIX Sparkling Water Maker vs Aarke Carbonator 3

Buy the SodaStream MIX if you want to carbonate juices, wine or spirits and want a spill tray and a pressure-release dial that cuts foam. Buy the Aarke Carbonator 3 if you only make sparkling water and want a stainless-steel machine that looks good on the counter. The MIX is plastic and more versatile; the Aarke is metal and simpler. Owners of the Aarke praise the build and design but say carbonation fades faster than SodaStream and water often lands in the drip tray.

• Choose the SodaStream MIX if you want to carbonate drinks other than water, or want controlled pressure release and a spill tray.
• Choose the Aarke Carbonator 3 if you make plain sparkling water and want a stainless-steel machine built to stay on display.
