bought fan from elmark some years ago. After installation the fan made high pitch sound (like flock of birds chirping). The technician came and claimed it was because of my ceiling. I had to convince them thru a no of calls to office to change the blades before they finally agreed. No more sound. I didnt have to pay because it was within the week of purchase. A year later the regulator spoilt. This time I got another fan/light supplier to come change it for me. Elmark service is rather bad but dont give up on fan. If you can wait and are prepared to pay cost, it'd be worth it if fan works well in future. My fan now working well for past few years.
