Product review (5 stars): Very well built exhaust fan.
Very well built exhaust fan and pulls smoke and cooking fumes out.  Loud when on high but it does the job and moves a large amount of air off the cook top. This is the second fan I installed in two years.  The first one was around $175.00 and would not turn off.  Went for repair parts and they were no longer supported after two years.  You get what you pay for and I am hopeful that this one will last longer than two years.
