Straw is poor quality

Style of the hat is great; however, the material/straw cracks and breaks terribly.

The straws are too wide and wobbly for little ones. They chew on it instead of sucking. Not worth it.

This product doesn't work. Specifically, the straw falls out constantly so you can't drink from it. Contigo, we expected much more from you :/ I would give this zero stars if I could.

the straws are a decent quality, however...  They are missing the molded ring that keeps the straw from falling out of the cup lid.  The packaging they come it shows straws with the ring but the actual straws don't have it.  They would be an okay straw for an open cup if that's your thing.  Avoid them if you need replacement straws though.

Lid does not go on very tightly, straw has already broke as it was flimsy.  I would not buy this product again.

Worked great until the straw became impossible to reattach. Once it started getting loose, the suction started failing and you can't get any water.

The design is perfect to fit in the Car cup holder. And, the 24oz is a good sized container. However, The plastic thumb tab to open the "Straw and Drink" has broken off, just after two weeks of use. Also, The Straw disconnects from the Mouth piece to often. Causing Me to have to open the top and reconnect the straw for "Designed" usage.

Straw either comes loose/crooked or falls down touching bottom of bottle making it impossible for my child to use/drink from it

The cup was nice as well as looks okay, but the straw was pretty weak and does not stay in the cup. The cup alone is worth the money however, just plan on buying more straws.

I don't use the straw, I tip the bottle and lid leaks bad.  If you are buying for the straw use then go for it. Rubber tip is already crumbling after 3 weeks of use. It's never been in dishwasher either.

The top of the straw ripped after only 3 months of school day use and now the thermos is continuously leaking in my son's lunch box.

The straw doesnt stay in place under the cap. It keeps loosening out and we need to tighten it every time

I do not like this cup. Biggest complaint is the lid will not close due to the straw

Very disappointed, the straw keeps falling off from 3 of them. Just one keeps in place.

On the inside of the cup, the straw will not stay attached to the top of the bottle, therefore making it impossible to drink out of.  It will literally fall back out as soon as you put it in.  I had to return it.

I ended up returning this item. The straw lid did not work and would not allow me to drink from it.

This bottle keeps drinks cold great, but the screw on the straw lid doesn't screw properly at all!! No matter how hard I screw it, the bottle keeps falling off of my hand, while I am still holding the lid. I kept screwing the lid back on, until today, when the lid got messed up when the bottle fell off of my hands for the umpteenth time! Now, the straw lid is completely screwed, and I can't drink through the straw any more! This is the last straw!!!
