I noticed some hairline cracks on my Denon remote yesterday. I purchased the 3805 receiver from Ubid last January, and it came with a 90 day warranty (refurbished).
Within that warranty period, I realized I received the older black foil remote, so I called Denon and they exchanged it for a new silver one (easier to see in daylight). Ubid aided in that exchange, although Denon didn't even bat an eye.
Anyhow, today I called Denon support regarding the hairline cracks, and was only on hold a minute. I told them about the remote - afraid it was out of warranty, and they said to send it in with the receipt. I told them it was B stock from Ubid. They said it doesn't matter, they've extended the warranty on the remotes for two years. I couldn't find the receipt, so I called Ubid and got ahold of someone within 30 seconds. The csr rep said she'd email me the invoice, which I received while we were on the phone via email. She even offered to contact Denon for me, which wasn't necessary.
My only expense is postage out for the old remote.
You just can't beat that type of service. Kudo's to Denon and Ubid.
