I was so excited about this product since I will be returning to work soon and plan to continue pumping there. However, I was quite disappointed. Based on the great reviews (and I'm definitely a review fanatic) I think my lack of success can be attributed to my pump. I have the Philips AVENT Isis iQ Duo Twin Electronic Breast Pump, and it has these soft silicone shields/flanges that secure to the suction part of the pump. I couldn't get the suctions through the bra slots without them coming off...and even once I had refasten them, they constantly would get caught on the fabric of the bra and come slightly off again. Thus ruining my suction. Overall this just wasn't worth the hassle to me, because the whole purpose of the bra was to be hands free (not constantly having to use your hands to readjust!) Overall, I think this product would be great with possibly another pump. Oh well, I guess I just won't be multi-tasking at work when I pump!
