I liked these as they lock and you can use w/o the straw BUT if the cap chips or breaks off they will no longer close at all so they are useless. We have had ours 4 months and I could not figure out why all of a sudden one would not close. One of the little prongs (teeth) chipped and no they are useless. These are made for kids so they should not break like that with a fall.

We have loved these water bottles for my son for preschool for about 8 months now, or so I thought! I wash them by hand regularly and I am not sure how I missed it, but there is black mold/mildew in the drinking mouth piece. I am so disgusted and sad... just writing this as a beware to other moms! Pros are that it has held up super well for my 4 year old, despite all the drops and dents! But the mold is completely unaccetable and in the garbage immediately. A water bottle we love is the Thermos brand with the clear straw.

Unfortunately the lid broke on one of the thermoses so it will no longer close so we cant use it. It just hangs open and is not sanitary to take to school or even use at all now. So sad because they didn't leak and it was a good size for my kindergartener :(

We really like these! They work great and we like everything about them!

Grand kids love these cups!

So far these have been fabulous bottles for an active 3 year old.

My son loves these. I love them because they are easy to fill, easy to wash, and don't leak!

Great bottle for school. A little small for sports

These are hands down the best water bottles. They keep water cold for hours. Perfect carrying handle for small hands.

Great sturdy cups keeps drinks cold. East to operate lid & spout. Love the loop handle for easy carry.
