I give this bra five stars for comfort, ease of putting on and removing, and the nice shape I get in it. I would give it all around five stars except that the straps disconnect when I put it on and I usually must put the straps into the slots, which is a bother. The straps connect in the back of the bra, also, so if a strap slips out when I am putting it on, I have to slide the band around to reconnect, then slide it back and hope it stays together. Still, I love the bra and after wearing it a few times, I ordered a duplicate so that I have one to wear while the other is in the hamper. The price can't be beat, either. I am 34DD and accustomed to paying twice what this bra costed (about $23). I have not tried running it it, but I can leap in ballet class and do some moderately bouncy things. I love how I can slip on a dress over my leotard or workout clothes and have a nice two-breast shape in this sports bra. I would order another one in a heartbeat if it was made in red.
