Zoku Premium Instant Iced Coffee Maker For thinKithen, Reusable Beverage Chiller Cools Hot Beverages in Minutes Without Dilution, Portable 11-ounce Tumbler With Spill-resistant Lid and Straw, Grey

Cold coffee in minutes. I haven't had any issues with drinks freezing as other reviews have mentioned. My only complaint is that the straw means I end up drinking quicker than normal but that's not the fault of the design.

used to drink coffee couple times a week. but ive been having iced coffee once a day with this cup! I use a doce gusto coffee machine to make the coffee. 5 mins later it is ice cold! Love it!

Too small

Been using this product for years almost daily and I love it. Just bought another for a gift. Works great 👍

Great product!! I was using the Hyper Chiller which worked well but still had to add ice to keep it cold while drinking. Plus I went through 3 of them because the plastic of the threads on the internal container kept cracking and splitting causing leakage. The Zoku is fantastic. No need to add ice and it keeps my coffee cold for a long time. So cold that I often have frozen coffee in the bottom - a coffee slushy! Highly recommend. It only hold a little over 7 ozs., but I make my coffee with Nespresso which makes a 7.3 oz. Cup, so it’s perfect!!
