I wish I could give it 4.75 stars instead of five because it works more slowly than I want; I want it to be magical and it isn't - but it is functional. It does work well and I use it every day.I love iced coffee. I am just not a fan of the flavor of cold-brew coffee and have a (now confirmed) theory that coffee flavor changes over time, with fresh coffee having a best flavor.I make two aeropresses of coffee every morning and swirl each (separately) in the hyperchiller for around two minutes before putting them in my travel cup with ice. Wonderful iced coffee for my trip to work. With iced coffee I can taste the regional differences in coffee beans and subtle notes of flavor that, at least to me, disappear when served hot. My morning cup is way more than a caffeine source, it is a source of pleasure, with the hyperchiller, even moreso.What I like: It works.What I dislike: It takes up room in my freezer. It takes time to chill the device before it is ready and cannot be quickly recharged for many back-to-back uses (if I have guests)  Read Less

Already had one for myself and bought a second for a friend. I'm thinking of buying a third for the office! I have a cold brew set to make concentrate which is nice but takes 24+ hours. Sometimes I forget/run out/am lazy and you can literally brew hot coffee into this thing and have ice cold coffee about 2 minutes later. From hot brewed to so cold in less than two minutes that the coffee doesn't even melt ice in the glass. Highly recommend if you're an iced coffee addict like me!  Read Less
