I installed this unit myself about 2 months ago. First impressions were good but not great. There were imperfections and blemishes in the brushed stainless finish even under the protective plastic cling wrap coating. None were deal breakers, but they were there. I expected better for the price. 
Mounting instructions were very good, and the basic installation was straight forward. I did have to custom order a 6" stainless steel vent hood for the outside of my house. I didn't like any of the junky plastic ones at the big box stores. 
As for performance, the lights provide just the right amount of illumination over the stove. And as for the fan, on low it moves all the air we would need, and is not very loud. This is good because there is a slight vibration on medium, and that vibration increases on high. It is not a strong vibration, but it is there. Again, I expected better for the price.
