Philips Avent Single Electric Breast Pump offers the comfort and convenience of fast, easy pumping at the touch of a button. It features 3 expression settings, all of which let you sit back and relax while the pump does the work. The pump features a soft massage cushion with textured petals intended to help gently stimulate milk flow by mimicking your baby's natural suckling patterns. For additional suction you can use the Power Cushion included. Unlike breast pumps that only operate properly when you lean forward, the our pump allows you to sit comfortably upright as you express, while the pump's angled neck lets milk flow naturally from breast to bottle. When you are able to relax, you can produce more milk. The breast pump has an uncomplicated design with a few, lightweight parts that are easily assembled and are dishwasher safe. You can also use it on the go with 4 AA batteries (not included). The collection container that connects to the pump also works as a bottle with the included natural breast-shaped nipple. The Philips Avent Single Electric Breast Pump is backed by a 2-year warranty. Replacement Massage Cushions are available in 19.5mm, 25mm and Power Cushions in 27.5mm.
