Manual one never worked for me, but just like with every pregnancy is different, so is every womans ability to breastfeed. My hospital gave me a manual pump, but it never worked. I ended up borrowing one from a neighbor that was electric and it worked beautifully. I plan on renting an electric one when this baby is born. MEDELA is an excellent brand.
I think I mentioned this in my post, but some hospitals you can rent the electric pumps from them.
I have the Medela pump in style...you can buy them on ebay and just buy new flanges...I wish I had done that. BUT I use mine every day!
I too use Medela. I like it.
