For my first, I breastfeed directly but since I had a huge over-supply, I still had to pump after each feeding. I used the Avent Manual Pump for this and it was efficient enough. For my second, I decided to pump everything out since she was a horrible feeder and I felt like I needed to spend more time with my first instead of feeding all day long. Initially I rented the Ameda (Hospital Grade one) from Homecare. However, the pump horns were not the right size for my nipples. It was too big and it was causing problems. I tried to buy horns that are smaller but the silicone one that they have in HK was too small. The problem with using Ameda in HK is that it's not as popular so it's harder to get additional parts / accessories. Anyways, after 1.5 weeks of playing around with the Ameda, I decided to get the Avent duo electric one. I LOVED it. Was much more comfortable for me. It also comes in a bag so that you can carry the pump around (important for me since I had to go on a couple of business trips so had to bring the pump with me). I highly recommend the Avent. One thing that you should be aware of is that you can't change the size of the horns for Avent so I have heard that women who have bigger nipples have had problems with Avent. For both my of kids I used the Avent bottles.
