I'm also using the pigeon電奶泵 for almost 9 months, and I've bought three now. Actually I don't think the pump is good, but I just tell myself that if the pump broken, then I can stop BF but still not yet broken again (my pump broken when my BB when 1 and 3 months old).
I also wonder if I have to buy a avent pump, as I also saw that , most BK mom don't like pigeon. Or I haven't used a good now, so that I think pigeon can used (althoght my nipple was painful and a little bit overpump -- longer than before , so terrible) . So I wanted to stop BF, but .................
I just pump 3 times daily now. I've not yet decided to stop or not .........
