Review on ☕ Zoku Instant Iced Coffee Maker: Fast Cooling, Reusable Chiller for Hot Beverages, Spill-Resistant Lid, Grey by Dana Berger

I wanted this for iced coffee. I was told to only put it in the freezer for a few hours but left it overnight. The next day I poured coffee into it and it's completely frozen, sold out in 10-15 minutes. It's ok as I didn't follow the directions exactly, but personally I wanted something I could leave in the freezer overnight or longer and take out when needed and it wouldn't turn my drink into a popsicle. just keep it cold This is probably because the layer of frost around the cup was 1/2+ inch or more (seems like a lot for what it is) so it was heavy and physically difficult to hold. Not used since then.
