The best insulated tumbler I have ever owned!
First of all, the cup is very well made. The tumbler is he perfect size for my hand, and I am a girl with medium sized hands. The print on the tumbler is holding up very well, as I have washed it 25-30 times already and have been using it daily! The lid is a perfect fit, there is no leaking. The lid is acrylic and has a rubber gasket deal that makes the lid fit perfectly. It isn’t a screw on lid. It is one that you pop on and off.
The Coldest Water Stainkess Tumbler keeps water insanely cold. I filled up my tumbler with ice water for the first time, and my ice had barely melted when I finished my water. The tumbler sat beside me empty of water, but there were still ice cubes left in it. After an hour, I picked the cup up to drink the melted ice cubes. And the ice cubes had barely melted. There was less than a teaspoon of water. I have never had a tumbler or mug or cup keep the temperature that cold! So crazy.
As I said before, I use this tumbler daily! My honest and fair review is that this is a brilliant product. You will not be dissapointed. It absolutely lives up the claims on the product page!
