Maymom Breast Pump Kit for Medela Pump in Style Advanced Breast Pumps; 2X Breastshields (one-Piece, 24mm), 4 Valves, 6 Membranes, 2 Pump-in-Style Tubing; Can Replace Medela PumpinStyle Valve

I already had Medela pump hence was left with only one option to buy the spares. But it is very expensive

Good bottles for storage, not too big so can use for smaller pump sessions during the day. Slightly frosted so no water lines when air dried and the narrow neck Dr Browns tops and teats fit perfectly so no need to use a second bottle when warming! The Bibs bottle handle actually fits better on here than the bibs own bottles so little guy can feed himself :)

Buenas refacciones

Bien mais il y a un cahiuchouc d'étanchéité a l'intérieur qui part a chaque lavage. Contraignant.

Just not worth the money

I needed more bottles to store my milk, and I saw these were cheaper than the Medela brand!! They are perfect for when I need to pump outside of my home, and need to store my breast milk. They fit the Medela PersonalFit Flex as well, so I can use these to pump directly. I also love that the measurements are engraved on the outside of the bottle, definitely is nice to see that the measurements do not erase or fade over time. I have also found that it is so much easier to stir/mix the fat that separates from the breast milk when it has chilled in the fridge. The bottles are made of some durable and sturdy plastic, I have noticed the medela bottles can be squeezed and you feel the plastic give, with these bottles this issue does not happen. So I am happy about that. If you are on the fence, I definitely recommend purchasing them.
