I am a RN and I bought this item because it was affordable. It works well but the problem that I have is the breast shields. I bought the double pump and the breast shields are the same--made out of a rubbery material and they have indentations all around the shield. At every indentation, you get a bruise (sort of like a hickey)and they all hurt. I use the Medela breast pumps at worka and they are pain-free as well as fast and quiet, which this pump is not. I have since purchased a medela pump and I love it.
