Can i trust this?

I am thinking of upgrading my 04 pre-facelift A3 to the 05-08 single grill and i have been searching eBay when i came across these cheap 'replacement parts.'
I just wondered if anyone could shed any light onto whether i can trust these to fit and for the quality to be as good as genuine?
Thanks
