I'm a 34DDD so I have a heck of a time finding a bra that fits, so I was actually rather surprised that this fit as well as it did.  It keeps me firm and upright even when jumping, and is usually pretty comfortable.  It does have stabilizers under the arms which can dig in, and I do get sore if I wear it for too long, but this has been regulated to my gym bra, so that isn't a problem.  The part I don't like is the fact that my boobs are not only in a full upright position, but also cone-shaped.  I'm not shy about pushing myself up a little, but these actually make me look like I was shaped by a funnel.
