Looks a more 'official' solution by clever use of VAG banners at the top but the cable and disc look very similar to the DHGate one I've ordered above. Slight difference in price though, mines only £17 delivered so that'd be the only reason I'd go for the cheaper one first.
EDIT:
Actually reading more about the company on their website VAG-Diags seem to be offering cables and software that mean you are legit as far as Ross-Tech are concerned, so assume no messing with hostfiles and internet blocking to make sure the cable works. They also promise good support so I'd go for it if I were you Eric and let us know what its like, in case my cable's crap..!
I think I'll bite the bullet and go for it, off on holiday next week so it'll be a month or so before I can give any impressions of it. Looking forward to the gauge sweep .
