Jasmine,
wat is your budget? I suggest so cos last time without experience, I spend ard $70 during promotion to buy a manual avent pump. N after giv birth when time to use, found those problem (very tiring n time consuming + leak at the other side), even get my hb to help to pump until he really found cannot like tat, so he borrow madela dual pump fr his colleague n we try. Found tat really solve all those problem. In the end he go buy same pump fr OG. I think tat time he buy was $200++. But with promotion should b less than $200. Can survey ard. My manual pump only use less than 5x n now sit in my cupboard do nothing. But benefit of avent manual pump is ithelp to clear block very well. When having engorge, probably due to it's bigger size, it can massage almost whole breast n help to clear blockage very efficiently n effectively.
