Worst inverter. Review on Microtek Twin Guard 1000 VA UPS

I had purchased this microtek inverter few months ago. It is worth Rs 6, 500 and had one year warranty. I stay in an area where electricity goes off frequently so this inverter is heavily needed. After using it for three months I am totally disappointed with the overall performance of this inverter. The inverter is heavy and has to be fixed. Also the inverter has heating problem. There is wiring problem in this inverter. Therefore while charging it suddenly stops to charge. The efficiency of the inverter is not good. After charging for almost ten hours it supplies energy only for six hours in night. Apart from this the inverter makes noise while it is working and disturbs the surrounding. There are no service centre for this inverter in our city. And if fit damaged then the repairing cost is too high. I suggest not to buy this inverter as you will regret after buying it.
