This bra (size 36C) is very comfortable and supportive without being uncomfortable.  HOWEVER, the plastic slider that connects the strap to the cup is a complete failure.  By about the tenth wearing it started to slide around so that the strap bunched up in one end of the slider and the plastic scratched my skin. Then a few wearings later, the slider snapped in half, rendering the bra completely unusable. I've included a photo so you can see what broke.
UPDATE: Amazon is apparently not allowing images to be uploaded by customers for this product.
