We have bought 2 Elmark fans and after 1 year both the sensor broke down. It was very frustrating dealing with the Cust Svc from Elmark as they are notorious for not following up with your requests. Just to get their repair guy to my place I have to make 5 phone calls. And on top of that it is also very expensive for just changing the sensor and they make me pay for the remote control too. Sigh.. and now my 2nd fan also breaking down due to the sensor.. and till now am feeling helpless with their extremely bad service.
