Product review (1 stars): Looks good but it will make you wish it had knobs.
Ask yourself one question before you buy;

What good is a range hood that turns off when it gets warm?

This is a very nice looking unit with huge fans that will QUIT when you need it most.  Just as soon as the cheap electronics get slightly warm they will freak out and just start blinking.  Like others have mentioned, you then have to unplug and plug back in to get it working again.  I also agree with the other criticisms found here.

My advice is you should keep looking.

Update -- tried the trick others mentioned of requesting repair parts via amazon email.  That process worked ok.  Received a replacement circuit board fairly quickly.  That board was clearly a completely different manufacturing run, even a different color.  What's more, it seems to be working.  I've revised my review to four stars but it's really more like a 3.5 star.  They can't ever have that fifth star because the repair board came in a box with not one word of directions.  I was completely on my own to figure out the replacement. Plus, after all, the thing had to be repaired.

Update -- Like others here the circuit board is freaking out again at a little over two years since purchase, but less than two since the replaced board noted above.  This manufacturer is clueless about electronic design, this product really is a P.O.S. and this company should be banned from selling on Amazon.
