so heres the deal I had a medela and a ameda. I leave the ameda at work and i leave the medela at home. I only pump once a day with the medela. I was using my sisters medela but she just had twins so I gave it back. So therefore I am carting my ameda back and forth and its a pain!!! I dont have the $$ to buy a new medela or ameda. I have found an afforadable used medela on ebay that I was thinking about getting. I know the ameda is a closed system and the medela is not. I dont know what to do.
