Review on Daystar White D-Ring Shackle Isolator: Bumper Protection & No More Rattling, KU70056WH - Made in America by Doug Bundy

Unfortunately I bought them but didn't mount them straight away because I was in the process of replacing the rear bumper and encountered a production issue that caused a delay. About 2 weeks after application, they turned yellow. Unfortunately it was now outside my return window. I wasted my money and now I need to replace it again. Not white this time. Discoloration aside, they fit well and feel well made. The first picture shows yellowing on both. The second shows the back, which hasn't been in the sun and is still white. Update: I notified Daystar and they replaced them with black ones. Excellent customer service.
