The black anodized aluminum grates don't work any better than standard ones
"I bought these grates hoping the coating would reduce sticking with meats and vegetables, but in my experience they didn’t perform any better than the standard non-coated grates that came with my grill. Cleaning has actually been more inconvenient because of the coating, I can’t use my usual metal grill brush and have to switch to nylon brushes or gentler cleaning methods, which take longer and don’t clean as thoroughly. I’m also not convinced there’s any durability advantage. The grates appear to be very similar in thickness and construction to the stock grates included with the grill. For the price, I’d recommend sticking with the standard non-coated grates and simply oiling them before use. I didn’t see enough performance improvement here to justify the upgrade."
