Product review (4 stars): Very nice unit and easily worth the price
We've now had this in place for a couple of months and are quite happy with the unit. We had a downdraft built into the island, and just didn't like that. Since we had no infrastructure (support, venting, roof exit) for this, there was some work involved in installing this. I did try contacting some of the installers that Amazon recommended, and not responded...so we did it ourselves :)

It take a little work to do this with two people, especially building the support structure in the ceiling. We had a further complication that the main house air ducts were just above the hole where this had to go, so the space was tight.

We had several issues at first with a non-working fan. After several go-rounds with the Cavaliere support team, they sent a new fan unit (the first pass solution didn't work). This was all done quickly and without cost. I had to swap out the fans in the motor housing, but it was not difficult.

Now it works very well. Even at setting 6 it is reasonably quiet. When we cook bacon, I smell it very little in the house, and do detect it outside, so it is venting nicely.

One downside is the tight fit of the bulbs in the housing. I wanted to swap these for LEDs, and even compatible LEDs are ever so slightly larger. I mean a small difference. And this was enough to make this quite challenging. It would be great if they came with LEDs or, at the least, if the housing weren;t so tight.

Still, they are in, we used this for Thanksgiving for 11 and we are very pleased.
