Aquaguard review: Water purifier genius model

I purchase the above product in 2019 worth 19000/ + and then in year 2020 gave a comprehensive service contract for two years @ 9000/+ which will expire in feb'2022 but a couple of days back on service engineer came and said that membrane filter not working and need replacement and will be charged as this change is allowed free only once a year. That means contract not comprehensive will be treated as cheating.. please take care before using Aquaguard products. Lot of complaints during this period. So I decided to discard the product if they don't repair properly and will never ever buy Aquaguard products..
