Query: If I only had one pump...

My cousin gave me her Medela Pump in Style which is a wonderful pump and I use it when I am home. The Isis Back-To-Work Pump is ideal for on the go situations. It is easy to carry to and from work, the pieces are easy to clean and assemble quickly, and it is very easy to use. I thought a manual pump would be a big pain and would be very irritating to use. Not this pump. I can also express as much milk in pretty much the same amount of time that I can with the double electric pump. The other nice thing is that I really like the Avent bottles which can be pumped directly into. If I only had one pump it would be this one. I was very skeptical at first because I heard from many mothers that in order to be successful at pumping you must have an electric pump. I think this pump is just as good and 1/4 of the cost.
