Query: so incrediably painful to pump

I am so disappointed with this pump. The reviews for it sounded so good but boy were they wrong. First off you have to continually press the hole open and closed to get the "pumping" action. Which to me is just silly because whats the point of a electric pump if you have to control it manually the whole time. Even at the highest setting I barely was able to get any milk after pumping for 15 minutes I finally stopped. In fact I get more milk using my manual 15 dollar pump. The worst part though is that the suction cups themselves are so uncomfortable and painful. My nipples feel raw after usage. They put nothing soft on the cups to make them comfortable. I had a pump with my son and it did not feel like that at all. I wish I still had that pump because this was such a waste of money. I'm currently in the process of returning. Please find another pump moms!!!
