I love this cup. It’s very convenient with the flip up straw as it doesn’t spill like the regular lid with straws. Doesn’t keep ice as long as I’d like but this now my go to cup. Love that it fits in all cup holders and hold 40oz.
I would recommend this to a friend!

First time buying it and was not impressed. Though the color is beautiful and size is perfect. Water does not last cold and the ice melts too almost immediately.
No, I would not recommend this to a friend.

Works for protein mix!

I love the straw! It makes drinking fun. These tumblers (?) are awesome. The temp control is amazing, and the straw helps me keep drinking! I can easily down two of them in the first half of the day (decaf became a thing). It also works very well with 3-4 tbsp scoop of protein coffee added

The best quality ever. I bought this for my girlfriend and she loves it. I strongly recommend buying this bottle for yourself or as a gift to a girl, especially if they’re active in the gym.

It's durable, keeps drinks cold with ice for over 24 hours, and best of all, it has a good grip for carrying.
