Query: Must have for working moms!!

I can't say enough about how wonderful this pump is. It is worth the price if you are a working mom who will need to pump often. I went back to work at six weeks post-pardum and this pump allowed me to continue breastfeeding my son until 8 months old when I gave it up for health reasons. The pump is not hard to use or assemble and it is much more efficient than a manual or single breast pump. I have the backpack style model and I didn't feel like people could even tell what it was when I would cart it in to work on my shoulder. I am expecting again and planning to use it this time around as well. This product was a lifesaver for me!
