I need a second hands free pumping bra for when I return to work in a couple of weeks.

I just saw this on the Simple Wishes site:

Has anyone used this? I can't tell if it will hold up the pump sufficiently, or if I am better off getting another regular hands free bra. If the B3 works, then I can just keep one bra on all day and don't have to keep changing every time I pump. No way am I leaving the regular pumping bra on all day *shudder*!
