I had low expectations for a nursing bra after trying many, many on including Cake Lingerie, Bravado, Motherhood Maternity and Shaperee.

This bra is great for the following reasons:
-it fits! I am usually a 34DD and ordered the 34F/G from Bravado but it was too small.  This 34G is a perfect fit.
-it has polyester in it so there is some structure and coverage that others didn't offer (the polyester does make it seem a bit 'cheaper' looking/feeling but I think it adds support so I didn't mind)
-straps are supportive without being super wide
-seemingly sturdy clip
