Keurig Kold Drinkmaker

2016 

This is a very big, very noisy and very expensive soda drink machine to put on your kitchen counter. It cost €370 and the brand-name soda pods cost more than €5 for a liter compared with €1 for a liter of bottled soda from the supermarket. It needed to be turned on 2-5 hours before it could make a cold drink. The Kold was discontinued after 9 months and customers were offered refunds.
