I have not tried it yet because it was a baby. There's a silicon cover, and it's a good configuration. I used a plastic bottle. I bought it as a glass bottle. I am satisfied. There is also a feature to prevent colic and durability is also good. It is not heavier than I thought.

Although the bottle is made in China, but compared to some of China's brand I still prefer BRON FREE, the glass is very thick, but also anti-flatulence device.

The most satisfying is this

Born free things did not have to say the quality, the most important is also sent a silicone sleeve, not afraid of hot. Three bottles, two for drinking milk, one for drinking water, very convenient.
