It is really a fantastic UPS. I have been using this for last 3-years and till date I don’t find any complaint about it. It is running smoothly. The powerful heavy battery has got 5-years warranty period and out of which 3-years is replaceable guaranty. You will get a brand new battery if there is any short of problem. Its cost is reasonable. It is reliable and long lasting power supply for specially Indian cities and villages where power-cut is routine work for the department. It is user friendly not much complicated. I personally recommend to go for this.
