The are a good size with minimal leakage. They are pretty easy to clean but the top may need a little tlc if they sit too long.

For our first kid, we loved Nuk's original Smooth Flow Anti-Colic bottles. They did not leak. They were very durable. We bought a bunch and took them everywhere. Based on that experience, four years later, we recently purchased Nuk's Smooth Flow Pro Anti-Colic bottles for our second kid without hesitation, assuming they would deliver the same experience. These new bottles are a disaster! The redesign is horrible with way too many parts! Worse, they leak all over the place. They leak when vertical because the vent straw functions a bit like a pipette. They leak when stored horizontally in a stroller basket, picture included. All of this has happened despite Nuk's website claiming "No leaks, guaranteed." This is completely unacceptable! Nuk, you have permanently lost us as a customer. We are returning these bottles because they are clearly a defective design!

These bottles would be a lot better if they didn’t leak from the sides when you shake them to mix formula.

These bottles leak so bad!
