Fantastic item!  Pumping was already difficult, and trying to tend to our twins simultaneously made it even more so.  I have had mine for a while now and am looking to buy a second.  I love this because I am able to get a boob-massage in so that not only can I make even more milk for my babies, but I can also have my hands free in case on of them needs attention.  Pumping is a lot of work, too, and whatever I can do to make it easier, I will try!  The velcro is very strong, even after numerous washes, and it lets you get it as comfortably tight as you need it.  The neck strap does get twisted easily, but I try to make sure its detached (which is easy enough to do) before washing it.  I'm larger chested and the regular bras were not really something I could work with, but this strap does everything I need.  You won't be disappointed.
