My first Roamio Pro I got in August/September last year had an issue where it wouldn't boot after using it for a couple of weeks. When I took it back to BestBuy and they plugged it in, it booted up fine. But the several times I tried it at home, it never booted. I exchanged it since this should not happen. And there was no guarantee it would not happen again. So far my replacement has been fine.
