I had the smaller version when I bought my De’Longhi Eletta (great machine btw) and didn’t expect it to be anything special - BUT it keeps ice as ice for 2 days! So I bought 2 of this larger version and they are perfect for a long day out or for sitting on my desk for work. Keeps hot things really hot, and cold things really cold, and is very very solid in your hand. Love them. Don’t love the price but as the saying goes, you get what you pay for.
