40 oz. is nice. Don't have to refill as often. Spout lid is perfect. Don't spill all over from a wide mouth while driving. Fits in my cup holders without the bumper. But the bumper is great. Thing never tips!
I love this bottle, it keeps my water cold, the top prevents leaks, and it's easy to refill. BUT, despite the fact that it was labeled on the website as dishwasher safe the bottle and package state that's it's not. I bought this bottle because it was supposed to be good quality and dishwasher safe.
This is my 6th Takeya purchase. I LOVE this product. It keeps my drink cool all day. And I typically have some ice in the bottle at the end of the week (if it has just been sitting). I've tried a number of other brands, but this one I love. I've gotten the 18oz, 24 oz, (2) 3oz and (2) 40 oz bottles. My family members got these as I love you gifts. If in doubt, bye one.
