I'm exclusively pumping, and I thought a hands- free bra was unnecessary until I actually bought this one. For one, I can operate the pump by myself without having to try to keep two flanges in place while double pumping. The bra holds them in place better than I can anyway, so I don't get leaks while I'm pumping. I can read something while I pump, so I tend to pump for longer and make more milk in a single session. I'm plus sized, and I was really impressed with how customizable this bra is. I took a little time adjusting the velcro and trying it on, and now it fits perfectly every time. I don't think I would have contributed to pump 6-8 time's every day for three months and counting without this thing.
