Maybe it's me, but I don't find it that good. The curves allow it to cam well, but that is at the expense of the range--it either fits precisely or doesn't fit at all. And I don't see why the shortest side is curved outwards: that also helps reduce the range. In fact, I have never been able to place one in the "other" orientation using the shortest side and the opposite one. The WC version has the short side curved inwards thus exposing two edges instead of one long thin round face, which, I suppose, would truly give it two options for placement. But having said that, I admit that I almost always find a placement for the only hex I own (#6 sent by mistake instead of nut #6).
