Product is good, installation is worst, 1. The guy was not ready to install the additional standard extension which is provided along the chimney, to reduce the gap between the ceiling and chimney. 2. Not even ready to remove the protection stickers used for safeguarding the chimney. 3. Not fitting as per the instruction manual, many screws and clamps are unused, also leveling is not very accurate. 4. All this additional cost of ₹600. Suggest to get this installed by known carpenter or electrician. Though the guy came for installation resisted to do all the above mentioned activities, I just rebuked him harshly and got all those done by him except the slight leveling issue & unused clamps.
