I bought this thinking it would make pumping easier and free up my hands.  However, once I got it I still found myself pumping without it because it was a pain to put on.  It sounded good in theory but it took too long to insert my pump shields and then try to get everything positioned correctly and zipped. I did like the support and pressure it applied to my sore breasts because exclusively pumping was really taking a toll on my body.  Ultimately I found that I could do without it and decided to return it after only a couple of uses.
