This K- brew + chill machine is a total game changer. We love iced coffee in our house and spent lots of. Now we can make it any time we want with any K-cup. The setup was super simple. Just fill the chill tank in the back with water and wait 4-6 hrs for it to chill and then you can brew ice cold coffee in under 3 minutes. And it automatically cleans itself after each cold brew!!!
