So far, so good!

Great cup for our 3 1/2 year old. Doesn't leak and we've dropped them a few times and the lids or cup haven't broke.

Perfect for car rides

I love that this tumbler can fit inside the carseat cup holder! I love that its spill free as well as able to keep the water relatively cold for a couple hours. My only issue with it was that one of the tumblers was much harder than the other when trying to open the straw to drink. Other than that it was great!

MOLD AND LEAKS

This design is terrible it is not leakproof at all and the slightest tip over it leaks and the straw design is mold central. They are so difficult to clean properly, terrible cup I regret buying these. Want my money back.

I seen these at the store and my 3yr old wanted them, so I purchased 2 of them seeing that they were 100%leak proof and they were on sale. I do like them but every single one of them leak. i have flipped the gasket over in the lid, still leak. I dont know maybe I got defective ones.

Ok cup

Nice cups. I like that they hold a good amount of liquid, stay cold for a decent amount of time and that the straw goes all the way to the bottom of the cup. My kiddos love them. However, we have found that they do leak, quite a bit if left that way for any length of time. My daughter fell asleep in her carseat with her cup tipped and in the 20 minute drive home she was soaked from the waist down, her carseat was soaked and so was the seat if the truck. These cups will be used for outside and we will stick with our other leak proof straw cups for car rides and inside.
