So, its been a year that I have bought this product. So far it has not shown any major issue. Probably this is a good choice for low budget. Some of the pros and cons are:-
Pros:-
It is very durable. Its been a year and works with almost the same efficiency as it was in the new condition.
The manual control panel is very easy to use. One can easily power on/off according to the need without any worry of shock from it.
The interfacing of it with the battery is quite easy.
It has a compact body and is lightweight. ie easily portable.
The various indicators present on the front side makes easy it very user-friendly.
Cons:-
The interfacing of UPS to the main circuit of the house is quite complex.
It is not able to sustain the high load even of an LCD. It shows the indicator of overload as the TV is switched on.
It makes very uneasy and disturbing fan sound when it is in use.
There has been a malfunction in it for a couple of times though, just short-circuiting in it.
Heavy Price. At this price, some other brands offer more technical specifications.
Overall this product is good and user-friendly. But one should buy it keeping in mind that it requires regular maintenance.
