The Spectra bottle is compatible with the breast pump and can be used as a baby bottle to feed the baby directly after pumping. It is leak-proof, has a good seal, and its flow is slow.Its size makes it comfortable to hold for a baby of a few months old, and it's also suitable for older babies. The cover can be easily removed for cleaning, and the material is durable.

Its material is resistant and safe, easy to clean, comfortable and the oz capacity is good for a baby from 0 to 12 months.It’s anti-colic, highly recommended

I would use this bottles exclusively just to pump. They are easy to clean and they have lasted about 2 years. I’m about to get new bottles for my new bundle of joy. Definitely recommend Spectra products
