Don't buy! I bought it because of the great review but I was totally wrong. 

The hood comes with no film protection on the body and there are some stains on it to make it look like a used one. But that's OK for me and I went to the tricky installation that cost me 3 hours.

After installation, I found that the range hood is not as efficient as it described. Compare to my previous 300 CFM Broan one, it does not have any improvement on the suction. The 900 CFM is a fraud. 

The touch switch design is ridiculous, the light will be turned off too when you just want to turn off the fan. Also the LED light is dim. 

This range hood is a disaster and a fraud. DON'T BUY!
