Hi guys, Today I will tell you about the worst inverter I have ever seen in my life. It is Ult SUN PACK 1025 PURE SINE WAVE INVERTER. I bought this inverter and for first 5 days everything was fine with it but then suddenly on 11th day it stopped working. After fighting with it for 1 hour it started working again but it provided backup just for half an hour in case of electricity cut. It is not so user friendly because the instructions given in its booklet are so complex. It is very heavy in weight so you can not move it easily from place to another. Its style and design is also not all good, you can not lift it up from the floor because of its improper design. When I called customer care they said that they would send their service man to fix the problem but till now no one has came and I have removed it from my house. I would not recommend this to anyone else. Please do not buy it.
