Product review (3 stars): Inexpensive, but you get what you pay for.
The outer casing is a bit flimsy, and the wiring for all the electronics is pretty much exposed, but that isn't a huge issue since its mounted high up.  The biggest issue is the fan is a tiny little plastic one that doesnt seem to move much air.  Then again this cost about 1/3 of what some other ones cost, so you shouldnt expect too much.
