I have this fan installed at my office and initially it was very good but after 6 months the problems started.
The OSC of the fan is not working now I am unable to stop the fan from rotating and this is just jammed and hence I now have stopped using it, because its just waste of time repair it and better off to be the way it is and also the fans top speed is also not at par, it is very slow.
So as you can see there are lot of issues and hence I would not recommend this product to anyone for now.
