This bra was rated by a running magazine as one of the best for large-breasted women.  I don't know what they consider large breasted, but it does not work well for DD cups if you are actually going to RUN.  I am glad that I tried this on the treadmill first, because there was significant bounce even with the cushioned deck.  I can't imagine what running on the ground would have been like.

The positive aspects are that the bra is relatively comfortable and will probably be fine for biking, rowing, or other low/medium impact activities.

In addition to the rating by the magazine, the other major selling point was the lower price point compared to the brand I usually buy (less than half the price).  I will keep this bra for low impact or lounging around the house, but if you are a DD cup and going to run, I recommend biting the bullet and going with Enell.
