My contractor said it wasn’t really all that easy to install. If I hadn’t ordered the crown molding , he said there would have been a gap that he would of had to creatively fix. I got the recirculating air type. However, for the very reasonable cost ,we are satisfied with it. I didn’t need a super high powered pro fan so this was even better than what I had before, and I rarely,used that . The only downside I’d say is it’s hi shine and shows fingerprints. It’s quiet unless you get up to level 4 but I’d expect that.  Overall, I’m quite,satisfied.
