Product review (4 stars): Last twenty months then fixed with parts from the company
Bought one about 1.8 years ago.  Suddenly it become default auto-detection mode by itself and shut down the fan.  Try to cancel it won't help.  I did this many many times and it just like to stay auto detection mode and no fan. Sometime it cycle through the buttons and stays on the auto mode.  I unplugged and re-plugged the power hopefully it will fix the problem.  When I re-plugged in the power, fans stay at level 1, halogen light stays on, touch button illuminated but NONE of them responsive.  Spend $389 dollars and only last 1.8 years. You judge it good or bad.  ............OK, contacted their support through chat.  They really stand behind their products.  They first sent the electronic control board, did not work; then they sent the display control panel itself.  Second time did the trick.  I left out the sensor and hopefully it will last because the smoke sensor became very greasy when I remove it.
