Product review (2 stars): Does not stay on with blinking lights flashing!
I was generous giving it two stars at this point. Having read so many good results as another buyer remarked he/she may have just gotten a bad unit.  As a builder I am always looking for quality and value. The unit is a nice looking heavy duty SS frame with powerful fans. My range hood has a faulty circuit board that turns on and of frequently on its own. If I unplug it and replug it, it's fine for about a minute tops. Having done a little research I found that some have a bad batch of of circuit boards. When I contacted the seller I was told only that there was likely a problem with the gas detector module and given instructions on how to remove it. I will update to a 4 star if it works without the gas detector module. Personally I would have been happier with push button switches instead of a circuit board that is like ly to fail with constant heat and winter back drafts!
