the directions to install are really poor. Make sure you figure out ahead of time how the brackets work and how they attach to the ceiling mount. If not, you'll get it up there only to find out you have the side brackets upside down (they look like should fit either way, but they do not).  No real instructions on how to attach the vent. I figured that out much later as well (you can lift up the outside sleeve once it's mounted and screw down your flexible tube.

btw, who actually makes a 6" hole saw that fits 6" venting! you really need 6 1/8" saw and the biggest they sell at Home Depot is 6". but that's just me not being a professional trying to do professional work. I'm sure the pros have the right saws.

the flexible tube that comes with the vent is awesome btw because it stretches so far. it saves a lot of money on the venting.

everyone has commented how cool this fan looks and the controls on both sides are a really good idea. you can tell this is a quality unit.
