You should have scrolled down to another thread or searched. This thread I describe differences in sellers and material used. Look at my posts.

The biggest problem with eBay: The sellers have no idea the material difference between ABS and Polyurethane. ABS plastic is super cheap and what most of those cheap lips are made of. If it's really stiff and doesn't flex by itself or you try twisting it, it's ABS. ABS will shatter and crack if it hits something.
Polyurethane is flexible and has give, if it hits something, it'll bend and won't snap, but costs more and not exactly friendly to painting because of it's flex.
These eBay sellers sell thousands of other parts for cars and have no idea what the lip is like they don't test it themselves, they literally use pics from cars from other sellers or online to show you what it "looks" like, even though it's not their actual product.
Buyer beware on eBay, it's the land of scam products.
