Bad experience of microtek intever. Review on Microtek EM 4170 Voltage Stabilizer for A.C.

I have purchase the inverter Model MICROTEK EM 4170 Microtek Stabilizer for 1.5 Ton A.C Voltage Stabilizer costing of Rs. 2000 but I am very much disappointed by this product. I use this for my 1.5 ton AC in 12 by 13 size room in summer but this always disturbing the out put line. I have purchase in July 2016 but after six months it got automatically sparked inside and from that time it is not working properly. The service of it customer care is also very bad. They never easily available for resolving the complain and this causes very irritating to us. As the company gives warranty of three years for this inverter but no one is giving proper attention to the complaints. I would like to say that this inverter was really bad model of the microtek. I am not satisfied with this inverter. I will never recommend buying this company’s inverter for domestic use. This is not user friendly.
