This thing is awesome.  It's super adjustable, well made & so much easier to use than others I've tried.  The only con for me (and it's more of a preference than a problem) is that the zipper goes from top to bottom to zip together.  It's a bit tricky for me.

But the flange openings are incredibly convenient and the ability to adjust this so that the openings are RIGHT where I need them has been a huge relief over the ones with just holes in them that zip with no adjusting capabilities (Easy Expression is the one I used for my first child and for the first couple of months for my second).

The material is soft and durable - definitely good quality.

On top of that, it is very supportive.  I don't feel like I have to lean forward or hold the top of it to keep things in place.  The others, if the bottles got half full, I had to lean forward because the weight would pull the flange enough off my breast to cause it to leak from the bottom and lose suction.

I'm a 38D and the L/XL/XXL size works for me, I had to adjust it to just about as small as it goes to get it just right.
