UPDATE: Yesterday I received my replacement band. It works. I have mixed feelings about the process. I am a little disappointed, but mostly for things that would be hard to argue over the phone.
CONS:
1. It took a few days before another Band was sent out. I expected a quicker delivery.
2. The Band they sent is a repair/refurb. The screen is in good condition but the surrounding plastic has wear marks and scratches. Not horrendous, but I expected something in nearly perfect condition, as I sent mine.
3. No replacement screen protector. I sent a band in with one, but couldn't get one back. If it wasn't a promotional freebee, I would persue a replacement.
4. Plain refurb box! I like to keep my original packaging for storage or resale value. Call me crazy, but most my nice electronics have original packaging sitting on a closet shelf.
PROS:
1. I got a free manufacturer replacement for a defective device, relatively hassle free.
2. My extended warranty is still intact and ready for a self inflicted exchange.
3. Support personnel were polite and very pleasant to deal with.
