An efficient and convenient breast pump without noisy motors or batteries, the Avent ISIS Breast Pump is an excellent choice for nursing mothers. The results of the ISIS pump are similar to most battery or electric pumps, and it distinguishes itself from other manual pumps with 5 soft petal-shaped cushion massagers and a unique silicone diaphragm that work together to mimic breastfeeding and stimulate the natural let-down reflex, helping to express more milk, quickly, naturally and gently. As you pump, the ¿petals" flex in and out, gently massaging the area behind the nipple, replicating your baby"s suckling action. The suction produced by the diaphragm is so efficient that you can control it just through the pressure of your fingertips on the handle, adjusting it to your own comfort level with comfortable one-handed action. Includes two 4-oz. bottles, 2 newborn nipples, Nipple Travel Pack, sealing disc and spare parts. Weighing only 1 pound, this light and portable pump easily fits into your purse or bag. Dishwasher safe. Imported.
