This is an absolutely fabulous tumbler for me :) I use a walker/wheelchair (that has a place under the seat for “storage”) for assistance and before getting this my other Stanley tumblers would literally do that in there - tumble & drip some liquid into that compartment. I always worried about liquid spilling on to the floor and others possibly slipping and falling - unbeknownst to me. Not anymore!!! This Stanley lets me fill it with water and toss it in that compartment and be on my way with no worries. I don’t use it for everyday use because i use my regular Stanley(s) but i do love this newest addition to my collection!

I love everything about it except the lid. It sounds like metal scraping when I open and close it. It isn’t a deal breaker, but i thought maybe after a week, the rubber would have seated properly, and it wouldn't make the noise. It still makes the noise.

40oz in toast! My oldest son absolutely loves his 1st stanley cup! The design of this tumbler is so nice, easy to carry during long walks on the trail and of course toe ice cold water!!!
