Lansinoh, also known for its nipple cream. This is a manual breast pump, purchased in the US. It comes with two sizes of breast shields: 25mm and 30.5mm. I wasn't sure whether to get an electric or manual pump, so I bought both. It seems like it depends on the person which one is better. If you want to try a manual pump, why not give this a try? The Lansinoh manual breast pump doesn't require batteries or a power source, so you can pump discreetly and comfortably on the go. It's portable and practical. At the beginning of breastfeeding, there's the "let-down phase," which is similar to a baby's natural sucking. It mimics the baby's slow, long sucking during breastfeeding. The ergonomic handle is easy to use with one hand, reducing strain on the wrist. It also features a ComfortSeal cushion for more efficient and comfortable pumping. Type: Breast Pump
