It is very very expensive product. Please do not buy any products from Kent. I own a kent prime which I bought 2 years ago. The filter change alarm went off before time this year and we got the membranes changed in March this year by paying 2700. Ideally it should have worked till June. But thats not such a big issue. So we ignored. Then the filters had an issue and we got it replaced in July by paying 1300. And I renewed my AMC at a cost of 2000 too. Now again there is water overflowing from the storage tank and the technician tells me membranes have to be changed again. Will have to pay 2700 again. Beware of buying Kent unless you have money to throw.
