Amazing!!! My son learned immediately how to suck and he is 10 months old!! The only possibly negative thing for some is that you have to wash it by hand because in the washing machine there are residues from the juice and milk in the straw.

I have tried all the brands.. The best.. Seals very well.. Doesn't leak at all no matter how you put it in the bag.. The straw is perfect for kids.. I give it 1000 stars and that's not enough

Convenient straw, easy to drink from, doesn't leak, doesn't spill easily, easy to clean, doesn't smell, doesn't break. Replacement straws are available for purchase for renewal.

Very good product. The only thing the little one has to learn now is not to lift it to drink. He sucks from the straw but sucks in air. He will understand where to go

Unacceptable. I challenge every parent to try to drink water through a straw to understand how much effort a child needs to make for a sip of water. I'm sorry I realized this late and made my child struggle.

I will only mention the negatives: the lid comes off very easily and can fall off or get lost while out and about.
The straw requires quite a bit of force to suck for the baby.
I consider it good for younger ages, for example, 10 months.
Its construction allows you to use it without the bottom part of the straw (the child holds it up to drink), so it can help a child to suck with the straw.

It is a very good product, I would definitely buy it again. And if the straw gets cut due to bites, there are replacements available.

Very convenient Nuk water bottle in various designs. It has a removable straw and can be replaced if needed. The most important and significant thing for me is that it doesn't leak when turned upside down. The only negative thing I would say is that the cap is easily removable from the bottle and the little one throws it away. Other than that, it is very good and worth its money.
