Product review (3 stars): not easy to install.
It's a little louder than I thought it would be but it looks great. They do however need to package this differently. All the installation hardware options are screwed down to it. You have to remove about twenty tiny screws and put another six back in just to get it configured for your vent type. Then you have to haul out an angle grinder with a cutting wheel to cut out the proper knockout panel which doesn't knockout. I also had to drill holes for where the vent attachment goes. There were only two pre-drilled.
