Product review (2 stars): At the rated CFM it should be able to suck up smoke with a lot more power
As others have reported, it's weak at sucking smoke.  Honestly, I don't think the CFM is accurate.  At the rated CFM it should be able to suck up smoke with a lot more power.  When using the front burner on our oven, I can see a lot smoke is passing the fan and going straight up to our ceiling.  Also, front right lamp keeps falling out shortly after it was installed.  Looks great but not very good functional with quality issues.
