Have the Medela slim electric gifted because I had wished for. I was so far from being satisfied! Could thus hardly milk pumping although the breast was obviously full. Hab therefore the AVENT manual breast pump ordered me. It is easy to assemble and easy to clean. The gel pad I find very pleasant. Heraußen When you how to trigger the MSR is it easy! After one should pump min per side according to the manufacturer in any case only 5 it also does not take forever. And the amount that you are doing adequately pumps off! Would I buy again
