Comments about Medela Sonata Breast Pump:

Since my baby is not born yet, I have not tried it out! However, shipping and customer service was superb. I sterilized the product components, charged the breast pump and connected it to my cell phone, which was easy and fast!

Great pump!

By Mel

from Olympia

Comments about Medela Sonata Breast Pump:

This pump feels just like the hospital grade pump I used while in the hospital. I was using the Medela PISA for about a week and it just wasn't getting me to express all my milk. This pump is a different story, I am so glad I made the switch.


Best pump

Comments about Medela Sonata Breast Pump:

I used to use the instyle pump from medela and I noticed my milk supply was going down so I invested into the new Sonota Pump and I absolutely love it. It's super light and very quiet. It has also helped me gain my milk back again. Amazing product and worth every penny!

Unreliable after less than one month

By Evie

from Reno, NV

Comments about Medela Sonata Breast Pump:

This is quiet, light weight, and portable. Battery can last for several pumpings. However, it started to go on the fritz after LESS than one month of use and is proving unreliable, which defeats the whole purpose. Sometimes it won't turn on, even though it says the battery is fully charged. Really disappointed.


Love it

Best Uses

    Comments about Medela Sonata Breast Pump:

    Best present from my mom! It took us a while to find one in stores, but I am so happy we finally did! The biggest thing I notice is the quietness (compared to my 3yr old Pump in Style I had with #1). Its important because I like to be in my babies room if I can while pumping & she just sleeps away. I've downloaded the MyMedela app and it connects well from what I can tell so far (only one week in). I'll be back to work in a few months and this will be very helpful. I hope to have a lot of milk stored up. I'm not 100% sure but it seems as if I get more milk with this pump vs. the Pump in Style. The different pieces are easy to use/assemble fast, not many at all. The carry bag is also very nice looking. I haven't figured out all the bells/whistles but there seems to be a lot of new things from my older pump. If we go for #3, this will definitely be used again! Happy baby, mom and dad. Happy family :)
