I absolutely love this cup, love the color! only problem I had, if I bought another one I will go smaller because this one can get kind of heavy once it's filled up.

Great Tumbler

I have a more expensive brand just like this cup and wanted another one. This is just as good for a more practical price. Love the color and keeps drinks cold all day.

Love it!

Gave this item to a friend. And she raves about it. It's helping her get her water in and fits in the car cupholder. And of course she loves the color.
