I recently purchased a complete set of supposedly genuine rotors, break pads, etc. from ebay but upon receiving them i noticed a lot of knicks, gashes and peeling on the rotors themselves.
Upon contacting the seller they stated this may be normal due to the manufacturer of the parts however i'm a bit skeptical about putting damaged parts on my vehicle.

I stored the images in my google drive since they are so large, you can find them here:

Here's the original listing on ebay for the parts i purchased:

Can anyone take a look at let me know what they think?

From what i can see watching a video like this, there is no damage like on my parts, that i can see in the video:

 

I didn't look at all your images, but the handful i saw show way more damage than I would allow. Those are a return with demerit for me... Edited to say, i would not do a return but instead get ebay involved, you should not have to pay for return shipping as the items are damaged.

 

If you don't mind me asking, what indicates they are not genuine parts?
