Personally, I think they all suck! I bought 3 with my first (a boy) pregnancy and they were sooooo uncomfortable I did not use them. I ended up using plain cotton triangle bras (no underwire) and just pulled them down. I put a burb cloth there to catch the falling milk that leaks out when the baby is eating so the bra does not get wet. Actually that is exactly what I am doing now with my second (a girl).
Maybe someone else had better luck than me, but all the ones I found were big, bulky and tight, just super uncomfortable.
But that was a couple years ago, maybe something better is out there now. I did not even look this time around, just used my trusty triangle ones. So comfortable and it takes 3 seconds to pull them down and put the burb cloth.
Good luck!
