Chimney is good. I bought it directly from the manufacturer. Initially the after sales support was also very good. Past 2 years am on annual contract. I find that after giving day and time the service person does not keep the appointment. One has to call repeatedly. Also the lady on the phone does not understand what is spoken. She was v rude and when I told her my time is not faltu insisted that I called her faltu. V unfortunate that a good product has such poor communication providers
