This has been advertised as an easy install and a black bladed fan, these Can't be any further from the truth.  

Some issues with install: the instructions were purely picture driven and had no words.  They seemed to have been out of order since I found myself routininely reversing the previous step in order to move on the the next step e.g.: sliding on housing covers which would be impossible without undoing the last step.
The hardest part of the install was wiring the motor part to the lights with on hand then supporting everything with the other while awkwardly screwing everything in place.  If you Don't hold the heavy motor part whining doing this, your wiring job would snap off.  I worked with other fan installs where all you needed to do was snap in a pre-wired job.  

The description of black blades is wrong.  The definitely are grey.
