The product definitely allows for hands free pumping but I found it difficult enough to get on and off that I'd rather just hold the flanges myself, it wastes that much time for me.  I have very large (H cup) breasts so someone smaller might have an easier time with this.  I didn't think the zipper closure was easy to do, would rather have had hooks or velcro in the front.  I also found it difficult to put on over my nursing bra so taking my shirt off, bra off and putting this on is what i have to do.  Not really a time saver. If I could wear this by itself as a bra it would be a different story but this does not offer enough support to do that.  What I wound up doing is cutting small holes in a cheap sports bra instead.  I can wear the sportsbra at all times, the holes aren't obvious with a shirt on, then when its time to pump I slip the flanges in the bra.
