When I first buy my pc I bought FRONTECH UPS alongwith it. I thought it would give about atleast 30 mins of power backup.
But as day goes by, it started to give about 5 mins of power backup after the electricity is gone.
When I reached their service centre in barrackpore, they told me that power was leaking inside and thus resulted in such a response.
When I demanded for replacement they told me that they can repair my UPS and did not replaced it.
It was quite a bad experience for me. I will suggest the company to replace such ups which are in bad condition.
