I honestly do not know. All I can say is that I didn't do anything that I am not sharing. My post was wondering if it was normal if Apple normally allows you to keep the band. I thought it was odd. I also don't think it was a defective band. The shadow you see really is one solid scratch and not some other thing. I honestly don't get what happened but I am sure I am just blocking it out. I workout a lot lifting weights and swimming and golfing and doing cross fit. I always use the sport band for those activities but maybe I forgot one time. All I can say is that I didn't try to fix it or sand it or sleepwalk or lying to anyone. It wasn't even my intention to bring this up. I just never knew Apple wouldn't want it back. I own 5 MacBook Laptops (One for each of us) - 5 Iphones 5 and higher and many other Apple products and even had a repair for a Apple TV and they exchanged - not let me keep it. Anyway, I just want it known that there is no game playing or sanding or trying to fix. One time I must have worn it and did something serious. Though I replaced the 4 links that were worn and the new ones were starting to have signs again.
