Not installed yet but love the grey blades. Very chic looking. 

Update:  Just had it installed by a professional electrician in our new house build.  It was initially wobbly which was disappointing. Then it just stopped.  The electrician returned and uninstalled.  The wired connection wrapped around itself with the rotation of the blades and frayed the protective cord. It got disconnected from the electricity. Working with the company now on resolution.
