Great price for their quality. Simple installation. Large enough to vent out my eat in kitchen. Quiet enough on low not to be intrusive, but still effective at venting cooking odors out. On high, it is louder as expected, but does the job. My kitchen does not feel like a sauna when I'm canning. Take the tape off the lights BEFORE You turn them on. 

Pros: Value. Simple to install. Efficient. Looks awesome. Six settings are plenty. 
Cons: None so far.
