Product review (4 stars): Fan works great, constructed very well and is quiet
Fan works great, constructed very well and is quiet.

I should have planned ahead of time when I was building my house, since the wiring of the sensor was the only pain after the fact, but luckily I have unfinished basement to make the work more manageable.

As a contractor the work was easy, but for typical homeowner I would hire a Licensed Electrician if not familiar with codes and wiring.

I plan on installing a lint trap between the dryer and new fan (15' distance) for extra piece of mind and no clogging of fan motor or future fire worries.  I am still on fence as whether or not this fan is code compliant for VA residential application but I had no choice and works great, would do it again regardless of code, since I believe some things can be done with common sense outside some of the code standards.
