I abpumpe milk since the birth of my daughter, because the baby is very saugschwach on the chest, I have dealt a lot with the "Pump on". As I got on a prescription electric breast pump, I first had no need to buy a hand pump. To pump in the office since I started working again, I wanted to buy a hand pump so as not to transport the electrical. I bought the Lansioh and the Medela Harmony and am really excited about the Lansinoh !! The result is better than with pumping of the electric pump. I can easily pump out within 10 minutes 100 ml. The milk ejection reflex is triggered quickly and the pump is very convenient. I'm much better coped with this than with the Medela Pump and own now 4 pieces in order to disinfect not always directly have. The Lansinoh I prefer even the electric. Pumpp ago. I just love them and can recommend it only. The price is great, the optimal handling and can be seen well if there is milk during pumping. The cleaning and the assembly are unproblematic! To all women have a strong buy recommendation !!!
