I have got one in my flat.since I have bought it with a battery and very next day it was connected to almost 9 bulbs, 3 fan, 1 television. The response of backup was fabulous never thought of it. As a rurban area when light get cut off for ever 4 or 5 hiurs it fully becomes a backbone for my hole home appliances.
It has a simple operating. Consist of various information about your battery like overload, ups on, mains on, fully charged etc depending on modles.
Overall I would simply say that just go for it.
