Does anyone use this aftermarket rear bumper lip?

Funnily enough, I know where an Akoya 53 plate in Bristol lives with that rear valance, it looks AWFUL with the non S-Line/S3 rear bumper. Plus the material might be made of cheese, so personally, I'd avoid.
 
Well maybe he bough it off this guy as well.it looks so right but I am just worry about quality of it ;))s3 rear bumper is too expensive for me....for now lol.
