Product review (4 stars): Looks great, does the job.
The first hood received was labeled as 30" but once we got the unit prepped and tried to install noticed it was a 36".  Called Amazon and they sent another unit over night.  Received the new unit around noon on a Saturday afternoon.  If you are installing this unit under a cabinet and have access to the area above I suggest you use toggle bolts.  As noted in a few reviews, when the unit is on high it can cause the unit to be loud and vibrate.  I placed a washer over the head of the toggle bolt and was able to get the unit tight and secure.  No vibration and the unit is not as loud.

The right fan is a little warped and does not spin in a true circular fashion.  You can see it wobble and it was scrapping.  I loosened the screws on the cover just a hair all the way around and the scrapping stopped.

The 36" unit was a hard wire, the 30" come with a plug.  The lights bulbs do not look as if they can be changed.  Not sure what happens if one of the lights goes out.  I will be calling Proline tomorrow with that question.  Overall, so far, the range is pretty good for the money.
