The bag fits perfectly on bikes with appropriately thick frame (in my case a cube Ltd Race). The only drawback I find that the Velcro is slightly undersized for closing the lid. So you get him down sometimes something bad, even if the bag is full to bursting. This effect is reinforced by the fact that the lid is pre-formed and thus can not be tightened to the motto "made to fit what is not fit".
But is really just a small drawback, otherwise good!
