I bought this sports bra after reading some of the reviews on it.  I'm a 34-DD so I need and like lots of support.  I've previously worn the Moving Comfort Fiona bra, and liked those a lot too, so that is what I'm comparing these to.  The Pros:
-Super comfortable-I could wear this all day and be comfy
-Easily adjustable-can adjust exactly as you want.  Would make a good maternity bra I would think
-Decreases the uniboob

Cons:
-sizes seem to run large-I bought the 34/36 D/DD and I feel like I would need to go a size smaller if I really wanted to reduce the bounce
-not quite enough compression for me.  Could be the fact that the sizes run large, but that Fiona bra definately keeps the girls where they belong.  This one not so much.

Overall I'm happy with these bras because they are comfortable for my regular workouts-weight lifting, elipticals, things like that.  I wouldn't consider running in this bra though-I'd bust out the Moving Comfort Fiona bras, which aren't comfortable enough for all day wear but will compress the girls enough to keep them where they belong.  I've reviewed the Fiona as well if you want my thoughts on that as well.
