Product review (5 stars): Excellent 750 cfm range hood!
I got tired of a low-end hood that recirculates the air back into the kitchen.  We have a commercial style propane range, and when my wife (the world's greatest cook) griddles beef for salisbury steak to feed 100 people, you guessed it - smoke alarms, throwing open the windows, and turning on external fans.  And the smell lingers for days!  I'm sure this situation was dangerous, too.  So I installed this hood and the required 6-in ductwork up through the attic and through the roof.  This unit really pulls some air!

I had one minor problem.  After successfully testing the fan and LED lights, I installed the hood. The fan worked perfectly, but after about 30 minutes the lights started blinking incessantly.  It was a faulty LED Driver.  It was a simple check with a circuit tester.  I registered the warranty and requested a replacement LED Driver.  Customer service was superb, and KOBE sent me a new driver by FedEx.  This kind of stuff happens.  It was no big deal.  I still give the hood and company 5 stars for an excellent product and quality customer service.
