Query: Difficult to use

I bought this breast pump after having my second child. I was able to borrow a Medela breast pump with my first child, but had to buy one of my own after my second. I chose this one because of the price. It is very difficult to maintain a proper seal to get proper suction. I knew I had plenty of milk to pump out, but this product could not seem to get at it. I was able to borrow another friend's Medela pump and had no problems, so I definitely knew the problem was THIS breast pump. My advise-- spend the extra money and get a Medela.
