Medela Swing

The Medela Swing is a mini-electric breast pump that pumps one side at a time. Like a manual pump, it's suitable for occasional use; unlike a manual, it runs on a power cord or batteries. It operates with two phases of expression that are supposed to simulate a baby's natural nursing pattern. Reviewers say it's compact enough to be carried in a purse, and some say it's as efficient as a more expensive professional-grade pump like the Medela Pump In Style Advanced (*Est. $280). Still, unlike a professional-grade double pump, the Swing can only express one side at a time. Those who need to pump several times a day are better off, experts say, with the speed of a double electric. The Medela Swing comes with a belt clip and strap for the neck or shoulder for mobile pumping. It's worth noting that the Ameda Purely Yours (*Est. $160, pump only), ConsumerSearch's Best Reviewed budget double pump, is only about $20 more if purchased without a carrying bag.

The baby product review book "Baby Bargains" provides valuable information about breast pumps in general, and the Medela Swing in particular. The greatest number of consumer reviews can be found on BabiesRUs.com, which helpfully organizes ratings according to features.
