When I had my daughter, 3 years ago, my lactation consultant turned me on to the Avent Isis hand-pump. The hand-pump was great, low cost and effective, but a little time consuming. Now Avent put out the Avent Isis Duo electric pump, and I haven't heard much rave about it. Has anyone tried the pump out? How well does it work? I looked on Babiesrus and they only had 3 feedbacks on it.
