I bought this chimney two week ago. I bought it in 13500 inr. Then I called service centre for installation, their technician was quite friendly he installed it in no time and asked for 400 inr.
As far as product is concerned this is a value for money product. Its suction that is 1000 m3/hr is quite good. Above all its auto clean technology is awesome but it has some limitations too that is, you have to be coutious about its servicing because it is quite cumbersome and difficult as far as cleaning its inner part is concerned. And if you live in any outer part of city or in some village it will be difficult for you to clean it after its initial phase of six month because every time if you have to clean it you need to ask for service man.
