Awesome

It's awesome. I just should've gotten the one with the handle, but I didn't think it would fit in my cupholder in my truck. When you flip the top back to sip out of it, the part hanging over kind of leaks on you. Otherwise it's a great purchase.

My thoughts

Wonderful at keeping it cold in my Florida heat. Just wish I could find a replacement lid as mine broke when washing and now I can't use.

Verified Purchase

We bought a black one in the store. The cup holders in our truck have no bottom so the shape of these is perfect for setting down in the opening and the fatter top keeps it from falling through. We then ordered a pink one because the screw on lid is great, especially for traveling.
