I'm a seasoned breastfeeding mom with now 4 children under my belt. I've tried pumps in the past (at least 2) and never had much luck so I've expressed milk by hand. This worked fine but seemed time consuming and my hands got tired. After reading many online reviews of different manual pumps I finally bought this one.I'm VERY impressed! On the first use I pumped 3 ounces in barely 3 minutes! The letdown feature worked nicely and once I had letdown the milk flowed into the bottle. Its compact and very quiet which I love because if I'm out noone needs know I am pumping. Taking it apart for cleaning is simply and quickOverall, I'm tickled pink that I took the plunge again and am extremely satisfied with this purchase. I would recommend this pump to anyone who had an established milk supply and limited time to pump.
