Everything seemed to work fine after the installation for first 6 months. Later there was a water leak which lead to sparks. So I have lodged a ticket with Havells service centre online. Technicians did come to check what the problem was but they never came back after their first check and didn't return my calls. This has happened with two technicians. There is no point of having a warranty for this product when they don't intend to give proper service.
