Worth the money
I love that I got to reuse the bottles that I used when my baby was first born. The attachments fit perfectly with no drippage. Also, when the bottles get squeezed no liquid comes out of them. These attachments are so perfect! They also come in a nice travel container with a small scrubby brush to clean out the tube.

LOVE THIS
I love this product. It is so good! Fit our comotomo bottles perfectly. We used these while teaching my son how to use a straw & introducing water to him. Very durable, easy to clean. Personally I chose not to use these with milk. We only used them with water. Great quality and a good price!

Quick to learn
Our babies first sippy cup and it seems like he figured out how to use it quickly!

Very hard to clean
This is a great product because it encourages the baby to transition to a sippy cup. However, this is very clumsy to clean and can lead to a lot of bacteria building up

It works ..
I like it but maybe because of the quality the straw rips so eventually it shrinks and I have to keep buying.

Doesn’t Spill!
Best transition without buying a new bottle! I LOVE this option and it doesn’t leak when they drop it!!! Best transition cup and great for speech development.

Easy transition
I’m absolutely in love with these straw cups for the como tomo bottles! It’s been great to be able to use the same bottles so it’s all similar and easy for my baby. They work great and my baby likes to use it during the day, as we are cutting down of bottles.
