Microtek Inverter. Review on Microtek Inverter

Before 1 year I have buy the Microtek inverter in my home because as I live in village so there is a too much problem of the load shedding that the light goes and come again and again so high by that in water but after one year of using Microtek inverter I realise one problem that it is consuming more power from me and the bed I have to change the battery water again and again as we have to put the distilled water in that so I have made a complaint to word the customer care and after that they saw the problem and they tell me that you should buy the new inverter of our company so I was really disappointed as I have paid the money for that and there was a guarantee of one year and after one year it it was useless for me so according to me we should buy the inverter of another company rather than the Microtek because its battery is tentative but the durability of that inverter is not long lasting as it was not for my better used as because it it doesn't work properly according to me
