I bought this product online in march 2015. I chose this UPS because it was very cheap. But I now regret of buying it. It was giving the battery backup to 15 minutes in the first 2 months after buying. I am having a pc with 500 watt smps( coolmaster) , i5 processor and 8 GB ram and in the time of power cut this UPS is not giving me 2 minutes of backup just to shut down it.
Two times I had to change my motherboard now I got know that it was due to this UPS only. I now really regret to buy this because it is not able to stabilise the current in the tine of power cut
