Thanks for the responses, guys. The majority has clearly spoken! I won't bother using this rim. I requested a refund of half of my total cost for the transaction from the seller, given that the other rim looks fine. Hopefully he is obliging. His description suggested looking at the photos and asking additional questions, as if he knew there was a problem with the rim from the start. However, there was only one photo with the light reflecting oddly off this rim that now shows that the issue was there, and no mention of structural damage.

I suspect he might try to say I should have asked, but honestly I do not think it shows integrity to put a rim up for sale that has structural damage and expect it to be the buyer's responsibility to find out. As I said, hopefully he is obliging. It's just $18.50.

Thanks for your feedback!
