Product review (4 stars): Great Hood with a couple of Caveats!
I read all reviews, good and bad before I decided to buy.

We were rebuilding our kitchen so we installed an outlet to plug it in and it the cord tucks in nicely behind the chimney.

It was nearly impossible to install the top chimney bracket with the crown molding in place.
That part of the install was a frustrating nightmare.
 Alas, we survived it and succeeded.
As to the loud beeps, it's true!
My husband located the beep behind the button panel. It's a black cylinder, smaller than the diameter of a dime.
He drilled a 3/16th hole in it and hot glued into it. The glue dried very fast and within seconds we tested it and it was quieter.
By the time we installed it a couple of hours later, you couldn't hear it at all.

The light shines down the back of the wall, but like another reviewer said, we like the way it looks.

The lights are too blue for me but I'll replace those and it'll be perfect.

For venting, we made a hole in the ceiling and vented into the attic above the insulation.

Overall, and certainly for the money, it is great. And it looks so good, as good as any expensive one!

Update: We sold our house and the inspection report stated that you cannot have a vent hood venting into the attic space.
So we paid to vent it out the roof. I feel it's plenty safe to vent above the insulation but it wasn't worth a fight at the time.
