Soooo after over 3 years of nursing different kids I finally got a clogged duct. For the life of me I couldn’t get it out - used my electric pump on high, hand expressed (nothing...), hot shower and massages.... nothing! This sucker! This thing is amazing!! It took a bit but it cleared my clogged duct! After 4 days of wincing when holding my children, cringing whenever anything touched my boob, this pump saved the day!!!I’ve also heard that manual pumps will get more milk out than an electric pump. Sooo I highly recommend new moms get this - even if it’s just in case of clogged ducts or mastitis.There are a few pieces to it so it’s not overly easy to clean but I mean if you’re pumping you know cleaning all the pump parts is a pain!
