My M7 developed a battery issue that various software interventions failed to fix. Unfortunately, screen had a superficial crack and case a couple of deep corner scratches. I chose the quick swap-out option with HTC Factory Repair for $19. This pays for UPS second day air, gives me a repair quote for the damage, and the option to pay for the non-warranty damage (or decline and get old phone back) and then get an immediate swap-out device for a turn around of about one week. I agreed to pay $180 for the screen and case damage repair and got back a few days later a completely brand new M7. Really excellent service IMHO.
