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!

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

Cold all day

Delightful. Keeps beverages cold all day, seals tight, doesn't leak or drip. Easy top rack dishwasher cleanup. The straw is not a favorite. Don't like the texture and found it difficult to assemble for proper uptake. Insert a plasiic straw through the plug and it's perfect. Have two and will be purchasing at least one more.
