I have a 6 week old and the pump I be use -lrb- for 6 week -rrb- break . I be not happy about spend $ 200 on another pump , but be so glad I do ! the pump be very quiet and very efficient . I can pump 8 ounce -lrb- 4 ounce on each side -rrb- in 5 minute or less ! I love that you can set the pump to whatever pattern\/intensity that you like . -lrb- you do this by pump the trigger to set the rhythm , then press the start button -rrb- this pump do not hurt at all ! it be very comfortable ! the only issue I have with it be that it be a little cumbersome to take the pump apart and store the milk ... -lrb- if you have a flat surface it be not a problem -rrb- bottom line , you will not be disappoint with this pump !
