I have The First Years Manual pump and it was the best thing. So I thought, this would make my life even easier. I have twin girls and was trying to build up a supply so my husband would be able to help me feed them. My letdown took forever with this pump. My nipple would hurt so bad with the shield it came with (Too small). If you have even average size breasts (which most women do after giving birth) your nipple will not fit into this shield. This pump took over 15 minutes to pump 4 ounces, wheres as I could use the manual pump for 15 minutes and have 6 - 8 ounces and no sore nipples! Bottom line, save your money by buying the manual pump or invest in a higher end pump.
