Definitely has the styling edge over my big ugly Zefal. I don't see it being much use, however, as it seems to be about the size of a dollar coin, and I can see your arm obscuring it when in the drops (that's what happens with mine, and it looks like it has at least three times the surface size of the one in your link). I'm looking for an alternative to my mirror, but I think I'll go with an eyeglass-mounted model.
See "Yes even I am thinking of getting a mirror..." thread on this forum, maybe even move this over there.
