I have a Medela Symphony pump that I used for 10 months as a fellow at Stanford Hospital and Clinics. I was the only user, it works perfectly and has never been dropped or damaged in any way. I also have a new pump kit and car charger to sell with the pump for $1200 total. Please email me at the attached stanford.edu address, at abcarrigg@gmail.com or call me at 858-997-4868.
