I waited until I used this for awhile, before writing a review.  I generally jog 3x/week.  So far I've bought various different bras to jog in, but this is the only one that makes my 36DDs feel comfortable.  I will admit there is some bounce, but nothing noticeable.  When I am finished jogging my breasts and back do not hurt.  I also enjoy the fact that it has adjustable shoulder straps.  The only issue I have with the straps is that the part where you adjust the bra is plastic, and this seems liable to break after awhile.  Overall I am highly satisfied with my purchase.
