I bought this because they're cute and I wanted to support what Ed and Emily do. When it arrived, I was pleasantly surprised that the tumblers are double walled and appear to be vacuum sealed. I put ice water in it yesterday morning, and by around 10pm last night there was still quite a bit of ice in it. This morning, all the ice was gone, but the water was still VERY cold. solid 5/5.
