I bought the product in the month of January after doing lot of research on other products .The product is very good to use as it is noiseless and non heating .Before buying it I went to Welcare showroom as it is a Coimbatore based company . They were offering me warranty of three years on motor , one year free service and maintenance . But I bought the product at amazon due to high gap in rate . At the time of installation they told me the motor warranty will be valid only for one year and no free services will be entertain as the product was taken from amazon instead of buying it from their showroom . The product is too good but I do not know what they are going to do with their services.
