Playtex Petite Double Electric Breast PumpThe Playtex® Petite Double Electric Breast Pump is a high-quality, discreetly-sized electric breast pump designed for ultimate comfort and efficiency. Three levels of fully adjustable suction let you control your own pumping experience. The unique, patented Soft Comfort® Breast Cups massage the breast while pumping and provide suction from the side, rather than pulling and tugging directly on the nipple as many other systems do, for ultimate comfort and fast let-down. The pump utilizes a unique closed system to protect breast milk against contamination. Can be used for single or double pumping.Features Massaging motion and suction aids in milk expression Designed to comfortably stimulate the breast Closed system protects against contamination from bacteria and germs 3 Easy-twist suction settingsKit Includes 1 pump motor unit 2 Soft Comfort® Breast Cups 2 Playtex® Drop-Ins™ System bottles (4 oz.) with nipples 10 Drop-Ins Pre-Formed Liners (4 oz.) 1 AC/DC adapter (12 volt) 1 set of tubing 2 liner rings, 2 extra nipple rings 2 sealing discs for milk storage 2 extra pump valves 1 instruction booklet
