I've been wearing these bras for *years* - they are great!  We currently have 5 kids and the oldest one is almost 9.  I've been nursing somebody almost the whole nine years, with breaks during most of each pregnancy.  This is the bra I use and when one breaks (underwires don't last forever), I just get another to replace it.  Fabulous.  My breasts tend to be slightly widely spaced for many bras, but this one - despite being an underwire - does not cut in on the outer sides of my breasts, which is really important to prevent plugged ducts.

Did I mention I love it!?

When considering other brands/styles of nursing bras over the years, I have always been amazed at the way they are often made to unhook/hook, in order to nurse.  Most of them look to me like they would be virtually impossible to do with one hand - and, really ladies!, when do you have more than one hand to get put back together?!?!  This hooking mechanism is easy, durable and no-miss.
