Hi, I started using a manual pump by The First Years, hated it because it always lost suction. I then had an electric from evenflo. It worked for a couple of weeks, and then the motor died. I was beginning to think I needed my baba's milk machine! I then purchased a Medela mimi electric, and I love it. I bought it off of ebay, but it was brand new, sealed in the box, with warranty. I only wish I would have purchased the double. I hope I don't burn mine out using it so often.
