Query: Buy the Pump In Style instead

I bought this pump because Medela is always spoken of so highly but it was loud, did not pump out much at all, and it hurt. I saw friends with the Pump In Style and was so envious of the short time it took to get a good amount of milk. I returned this product because it was useless and a friend lent me her Isis Manual pump which works much better and feels much better for my occasional useage.
