I am very happy with this purchase, and I definitely recommend it to all mom's planning on pumping.  This is not meant to be worn all day, this is just for pumping.  My only complaint about this is while the back is adjustable, I'm between sizes with the front segment.  If I put it in, it's too wide, if it's out everything is squished together.  It's better than nothing but if they would make a little more front adjustment I would LOVE this product even more.  Or if it would clean the pump for me afterwords. . .
