I never provide reviews or feedback to websites as a general rule, however I bought this in November after much research on the web and it has exceeded my expectations. This is the real deal. It is so warm that I've turned the thermostat down to 60 at night now, and I'm the type of person who can't sleep if I'm cold. I used to keep the room at 66 degrees. It is about 5 or 6 inches thick but light weight and I haven't seen a single feather come out. I've never seen a 10-year warranty on any other comforter, however I don't believe I'll have a need to use it based on my experience so far.
