They spill when tipped over! I thought with all the technology used inside, they will not spill. Disappointed.

Choking hazard for small children. Product should be recalled or redecorated to attract older children.

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.

One star because a cup designed for children should not have a removable 2 inch section of flimsy straw - a choking hazard and gets lost often, rendering the water bottle unusable.

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!

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.

Keeps drinks cold. Spill proof

Nice quality cup for little ones, easy to wash

The kids love these cups and they are worth the money.

Love this product because is very helpful
