I bought this pump before I had my second son and I wish I had it for the first one as well. With my first son I used a different brand pump. I breastfed and pumped for 14 months. I work full time a hour away from home, am basically gone for 12 hour a day and pump 3 times while I'm gone. I lived in fear that the other pump would fail on me and the power cord quit TWICE while I as at work. NIGHTMARE! When I found out that I was pregnant for the second time . . . . . a Medela pump was the first thing that I bought. I have not had one issue with the pump or any of the parts. When my second son turned 8 months I started having decreased flow problems. I wasn't sure if it was mechanically issues with the pump or a decrease in my flow. I called Medela customer service and the service person walked me though a check list to review my pump. She helped me determine in 10 minutes (while I was pumping at work) that pump was working correctly and that I was actually having flow problems. I can't recommend this pump more highly!
