Product review (4 stars): Its defiantly DIY-able but its gonna take you the entire weekend in an older house (fit to finish).
Location: Florida
This worked out well for me. As others noted it came with a plastic flex tube that specifically says in the directions not to use. I needed a much longer one anyway so that was not an issue for me. The remote seems silly to me, its like the remote that came with my car stereo (why?).

My issue with install was: there were no studs that lined up to mount to. I had to cut into the wall and install a piece of wood to span the existing studs to give me something solid to mount to. Florida seems to allow for studs spanning around 20 inches which is odd.  This causes quite a bit of structural vibration on high. Kinda like a whole house fan (a huge fan in the garage that sucks air into the attic). The lights are fantastic. It looks really nice hanging on the wall. I just wish i had mounted it a bit lower because it doesn't suck up stuff as strong as I assume it could. Maybe i need a larger duct, an inline blower (25 foot run) or just lower it a bit.

It works though, clears smoke in no time. Something to note, if there is any question when you mount it, mount it lower than you think you should (closer to the minimum height not the maximum). Also, if it comes down to needing only 2 inches of the other duct sleeve (the extension) you will have a problem because there is some metal in the sleeve that needs to be cut away. Either mount it so it uses one sleeve or mount it low enough that at least 3-4 inches of the second sleeve shows and you will be good (no cuts or aggravation mounting it in place).

Its defiantly a 2 person job. Not because it heavy, you just need an extra set of hands to help in some situations when installing it.
