Product review (1 stars): Poor fan, Clock is off
If I could give this a 1.5 star, I would cause aesthetically it looks pretty good.  Functionally, there are some major issues:

1) The digital clock is on a 58 minute hour.  Over the course of the day, the clock is off by 48 minutes.  Being right over a stove that has the correct time, this is incredibly annoying.  I can not believe that in this day of age, this could be an issue.

2) Functionality - I can not get the fan to turn on for more than 60 seconds.  Huge pain if you are cooking something to have to continuously turn on the fan.  In addition, the 60 seconds of fan that I do get, is incredibly low quality.

3) Customer service - I emailed them immediately after our contractor installed it (2-3 weeks after purchase) which about 3 months ago.  After a second email, I was told that they would be sending over materials to fix the clock.  After a couple of weeks went by and I didn't get them, i contacted them again.  Supposively the replacement parts are coming, but I'll believe it when I see it.

Maybe I just got a lemon, but for something that you need to install in and do some work, I would not buy this unit because you don't know what you're going to get.
