This product does not work for hands free pumping! Not unless your nipples are on the bottom of your breasts and you enjoy the feeling of metal pinching you the entire time. Thats right. There are metal rings which punch you the entire pumping time because they arr poorly located. Who puts metal on a bra?! You have to hold the flanges of your pump to keep the bra where it needs to be. Garbage. Dont waste your money.
