Product review (5 stars): Happy customer
Real nice product.  Looks clean and is very quiet.  I bought some larger fasteners than those included and used lock nuts, but I'm a little anal.  Needed to add a little framing in the attic and an outlet.  The instructions were decent, but if you're doing it yourself you'll need some light construction skills and a little common sense.  I installed on an 8' ceiling, so I needed to shorten the ducts.  All in all, very happy with the purchase.
