I have purchased in November 2016. Hardly 2 hours it worked, sensor got failed and replaced the sensor. After replacing the sensor, again it was not detected the tank full and tank empty. Some time keep on over flowing the storage tank and some time tank will be empty and it doesnt refill. Within 3 months period, membrane got failed. Since it is a consumable item, ZeroB asked me to pay Rs. 4000 for the new membrane.
Never seen such a waste product and worst service in my life time.
