If you need to go back to office to pump, best to get an electric pump. I use Medela free style. So far so good. I bought at 699 from baby fair and u can buy from Amazon at around 500 but it doesn't have local warranty
For me, spectra is the best. it is the only affordable hospital grade pump i can find. with very good suction too. enough said. i have both the s1 and 9+
previously using avent I seriously the suction I don't find it good. medela not bad my friend said maybe you can try it maybe try spectra.
I using medela so far so good.. most of the time kiddy palace have promotion
spectra!! cheap and good and portable. I liked the 9+ model..
I am using spectra 9s ! It's great !
