Product review (5 stars): Seems high quality
Pushes some serious air.  Using it over my 48" range.  Seems well built and relatively heavy duty.  Only issue, The plug for the motors is an actual plug for an outlet.  I would have preferred to hard wire this directly from the motors/board/whatever but it would have required some serious disassembly of the unit or to cut the existing cord.  Otherwise it is well built, timer feature works nice, and lighting it produces is very nice.  I've been using it regularly for about 2 months now, no issues.  Grates are easily removable as well and I just throw them in the dishwasher.
