this pump be pretty terrible . some people like it , and for some people it work for a week or a month before give up the ghost . maybe Evenflo have poor quality control standard , but mine do not even work once . I get barely anything , and it pinch painfully to boot . I use a medelum until the motor finally give out -lrb- it be a hand I down -rrb- , so it be not like I have never pump before . complete waste of money , as it sound like you be just roll the dice on if you get a good one or not .
