I'm a new, first-time mom (our daughter is 6 weeks old), and after a week of holding onto the breastpump parts while pumping, decided it was time to look for something that would let me pump hands-free.  This is absolutely perfect!

The sizing is great (I was a 36C before, somewhere around a DD or E now, and ordered the L/XL size).  The velcro pieces are wonderful, the sizing is remarkably flexible and well thought out.  The nipple shields stay perfectly in place, and there's enough support to hold onto the bottles I pump into (so far it's taken about 6 oz of weight, I assume there won't be a problem if/when I'm pumping more).

I'm very easily able to use the computer or talk on the phone, etc... only limited by the length of the tubing now.

I couldn't have asked for a better product!
