I have purchased 5 AOSmith for two flats and replaced three coils within three years and I am sure the rest two are waiting for its turn. Any how I am going to replace with other brands next time. I have other brands as well using it from past ten years never had this problem. it is Unfortunate that this company is taking us for ride. Each time I replace they charge Rs 2200/- . The technician is not from company they have local electricians who are trained by the company.
I am very poor in writing a review but this is my first review as I am frustrated. I really started believing in reviews. So buy products only after reading a review.
