Product review (1 stars): Serious Design Flaws...  Caveat emptor
Bought this in January of 2014.  about 6 months into owning it the auto sensor got clogged with grease and the unit ceased to function...  the lights came on the fan was on its lowest setting and none of the buttons on the control panel worked.

I removed the sensor as indicated by customer support AND online sources, which was very difficult while installed. once i removed the connections and the sensor, the hood functioned as it should.

about a week ago (November 1 2015)as i headed into the kitchen, I noticed that the fan was on its lowest setting, the lights were on and the buttons again were unresponsive. I tried the remote, to see if that would work, but it did not.  I have unplugged this device to keep it from being on all the time and am going to contact the manufacturer..  this is dissapointing, because the unit is handsome, and had a fairly high CFM rating.

Considering all the negative responses by purchasers, you would think that amazon would contact the seller and open a can of whoop ass on them.  Unfortunately, to date , this is not the case... Ill update this review with any news from Golden Vantage... I also may try the Voltage Regulator fix as suggested by Ychin San in this review (http://www.amazon.com/review/R1GM668ESBR1K/ref=cm_cr_rev_detmd_pl?ie=UTF8&asin=B008UEJS7Y&cdForum=Fx6BPE32LAQMZ1&cdMsgID=Mx6KFP4AC5T1O0&cdMsgNo=5&cdPage=1&cdSort=oldest&cdThread=Tx3025MY3QOL513&store=appliances#Mx6KFP4AC5T1O0)

So i reached out to GV and they replied back asked me a few qustions and then sent me an entire electrical system for the hood.  Control panel, circuit board, wiring harness.  however, what they didn't send was any kind of instructions...  crap i had forgotten how much of a pain in the ass this thing is.  some takeaways are as follows.

=>>  the build quality on this product doesnt extend beyond the fans and the stainless body.  the electronics are quite flawed.

=>> there are 4 different length screws holding the light panel on.  why they couldn't standardize this and come up with another method of securing the panel, and the controls with the longer screws is beyond me.

=>>  unless you want to take the entire unit off the wall and disassemble the fans, you won't get the light panel "out" just able to move it around.

=>> the new control panel came without the gas monitoring control which is fine, i disabled the sensor, but the controls are wierdly segmented..  you can turn the light and the timer on any time you want, but to turn on the fans, you have to actually use a power button and then turn on the fans.  strange.

Its really too bad.. the CFM of this unit if awesome and it looks good.  unfortunately it just doesnt seem to be able to overcome some design flaws.  I would like to suggest to others to buy this item, but i just cant.  If i had to do it over, i would buy one of the more expensive ones that I overlooked to buy this one.
