My son's new favorite forever tumbler!

I have tried about a dozen different tumblers for my 2.5 year old son who loves water and this one is by far the best one! The size is perfect, design is super cute, no issues with leaking so far, overall it meets every requirement I'd have. Straw is easy to drink out of, no issues with suction. It keeps drinks cold with ice and we intend to purchase a second one. I would highly recommend this tumbler to anyone with kids!

I like it and the state is made where it does not leak.. although if you are someone who doesn't want to kind of bite down or push down on the straw w/ your lips you would want to go with something else. However if that doesn't bother you then I highly recommend it!

This is one of the best thermal cups that I own I've bought two of them in blue and green and they are what I drink out of every day and my drink stays cold exactly like it's supposed to I love both of my thermal cups and I love the way the lid just screws on and stays where I put it
