Great!

[This review was collected as part of a promotion.] I didn't realize how large the cup was but I should have - the size is listed .
It's perfect - I have a job where I where a mask and can't drink water much except on drives. My other water bottles didn't fit in my cup holder OR held too little water. This is perfect and I'm getting plenty of water now even if it's a lot of water a few times per day
I also love the shimmer blue color! Great cup!

Whole family is obsessed

[This review was collected as part of a promotion.] I have 5 of these and will keep buying more. I love how all the straws and lids mix and match. I also buy these when they’re on sale for Christmas gifts. I got my husband 2 of these same 40oz tumbler on accident but it’s great to be able to throw a clean lid or straw on there with needed. LOVE throwing them in the dishwasher. I do not waste my time on any other tumbler brand.
