I bought this pump after reading glowing reviews. I had been using a pump-in-style (my son was premature so I needed the big guns) once he was older I thought I could go to a manual pump it seemed like it would be easier to use for a quick pump before I left him home with dad for a few hours. I really gave it a long trial- two months but really did not find that I could get more than a few ounces out at a time. It was uncomfortable on my breats even pinched and rubbed a blister once. Finally I just gave up on pumping all together. If you are lucky enough to have an electric double pump don't think the grass is greener elsewhere. It wasn't for me.
