The hood itself works well. Here are our issues. 

1. The fan auto off button does not work. Supposed to hold 2 seconds for it to shut off. 
2.  We have 10 foot ceiling so an extension for the vent was required. The issue is the extension and hood colors do not match. We tried numerous replacements and even tried a black slate unit but still colors do not match. This is a big issue and huge disappointment.
