I absolutely LOVE these tumblers! Not just super cute, they serve the purpose I was looking for. I am able to close the top and throw them in my backpack that I carry to work without worry. They are smaller than my usual 52oz so I just use 2 cups if needed. The issues I had before, were the 52oz is super heavy and my shirt was always getting a little wet as it sloshed out the straw hole when walking into the building. Now I'm hands free with all cups in my bag. Another benefit is since the lid screws on, I no longer have the issue of my cup falling off my desk and having a huge mess to clean up when the lid pops off. One minor flaw that is not a big deal if you are expecting it, often when I raise the straw for the first time in a full cup, a small amount of liquid comes out of the straw and lands on the lid (think of those little fruit cups your kids have you open). Now be mindful my cups are laying down in my bag and not stsying upright after I fill them. Again for me this is super minor and worth the benefits I'm getting. All of my teacher friends want one now.

Sturdy, easy to clean.

Love them. Love the way the straw folds up and is covered

This has to be my most favorite brand!! I love it more than of my expensive name brands

Keeps my drinks cold and it’s really leaks proof

I LOVE THIS CUP. GREAT FOR OUTDOORS.

Great product with the ability to lock straw inside.

Great idea but when you open the auction ouahes out the liquid and it squrts ya.

It doesn’t keep the cold inside it

Good and sturdy. Dishwasher safe
