Can Sonata be repaired at Medela or a local repair center?
Call Customer Service for any type of service needed to your pump. We will troubleshoot to determine the cause of malfunction and help you to restore it to working order. Medela does not repair motors of personal care products like the Sonata even within its warranty. If within warranty, we may replace the unit after verifying the purchase date with a copy of your receipt. If outside warranty, we suggest purchasing a new unit.
What is the size comparison between Sonata and Freestyle?
Sonata weighs 2.2 lbs. and includes an integrated handle for a secure griop when moving from one stationary pumping surface to another. Freestyle weighs less than 1 lb., fits in the palm of your hand, and includes a belt clip designed for mobile pumping.
What’s the difference between the two pumping rhythms?
The Signature Rhythm (Rhythm 1) is inspired by our popular hospital-use Symphony Breast Pump. The Lifestyle Rhythm (Rhythm 2) is an alternate rhythm for when you want to change your pumping routine. It includes additional benefits of longer battery, and quieter pump operation when you need it.
What Rhythm is best for mom to use?
Every mom reacts differently to the vacuum feeling of a breast pump. Sonata’s two rhythms are available to customize your pumping session. You may find one rhythm more comfortable or effective than the other.
Are Sonata parts compatible with other Medela breast pumps?
Sonata’s double pumping kit components and power adaptor were developed exclusively for Sonata, to optimize performance. PersonalFit™ breast shields are compatible with all Medela breast pumps.
