Product review (5 stars): Good so far!
We received the hood rather promptly.  I think within a week even though estimates showed weeks later possibly.
The product we received matches the picture.  Ours does not have a clock, but it does have a 15 minute timer which is useful.

On the higher settings, it is a little loud, but it's just the fan.  There isn't any rattling sounds or anything like that.

Ours arrived with a small scratch on it where it rubbed in shipping.  Not noticeable by those who didn't install it.  I don't think my wife noticed yet and she'll be cool with it if she saw it.  I'm ordering LED lights to replace the halogens since we leave this on a lot.  The light bulbs are in a GU10 socket and can be popped out pretty easily.  The color of the existing lights are good and it does a good job shining over our cooktop.

The directions are very limited.  It basically says unbox, use brackets, mount to ceiling.
I had a professional come out to do it, but I probably could have done it myself.  Watch a few videos online to find out how to install it.  (Probably could have saved some money.
