The newest offering from the pumping pros at Medela, this high-tech, double-electric breast pump is designed for moms who pump several times a day. Compact, lightweight and portable, the pump comes with a carrying bag and all the accessories you need to get started.

Like the Pump in Style Advanced—Medela’s similar machine that’s very popular with working moms—the Sonata has 2-Phase Expression® Technology with a one-touch letdown button. You get more milk in less time when double pumping when compared to single pumping. There are also two pumping rhythms to choose from.

Inspired by the Symphony, Medela’s hospital-grade pump, the Sontata has powerful yet gentle suction and is designed to deliver consistent results in a more portable and affordable package. (Affordability is relative here, but for working moms who want to give their baby breast milk, a great pump can feel worth its weight in gold.)

Unlike the Pump in Style Advanced, which has manual controls, the Sonata has a touch screen display and digital controls. An adjustable timer helps you manage your pumping sessions. You can sync this machine with the MyMedela app, a resource for tracking your pumping sessions, charting your baby’s growth and accessing information on lactation designed to help you reach your breast milk feeding goals.

Two features that really distinguish this pump are its quiet operation and rechargeable lithium-ion battery. This is a super quiet machine—moms report that they can even join a conference call while pumping, unthinkable with the Pump in Style. Rechargeability means you can use it anywhere, whether or not you have access to a power outlet—this is a very big deal depending on where you pump. Moms love that when the Sonata fully charged, it pumps as well as when it’s plugged in (the Pump in Style’s eight-AA battery-powered suction is much weaker).

There are a few downsides to this pump as well. The digital display can be hard to read. The charge only lasts for two to three pumps, and there’s no low-battery warning unless you are using the MyMedela app, so you need to remember to charge it between uses.

There are more parts for this machine than for the Pump in Style, so there’s more to carry, assemble, clean and replace (that said, the parts have fewer nooks and crannies, so they’re a bit easier to clean). The pump parts are considerably heavier, too; when the milk bottles start to get full, they may become too heavy for a pumping bustier and you may need to hold them. Finally, the pump parts are not compatible with Medela Pump & Save storage bags.

While the Pump in Style Advanced is still an excellent, solid option for daily pumpers, the Sonata’s digital interface and cordless operation will earn plenty of fans. If you pump at work or on the go, getting an extra set or two of pump parts will make your life much easier. (Note that, while you can use the same flanges and bottles as other Medela pumps, the rest of the parts are unique to the Sonata.)
