Well, I've just got one of these. It doesn't have scroll wheels, so I don't like it for itself. But its 40mm diameter ball fits my converted Trust device neatly, and the performance of the H2000 optical sensor I used seems pretty much the same as that of Logitech's sensor. So I'm a happy pigeon. Thanks! -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
