I had purchased a new pc before and a microtek ups before one year. It was very good ups from microtek. I used it with my pc, speakers, printer.
All together and it gave me 30min power backup.it was very good in taking load. One time connected it with my cooler. It worked for 45min without any problem. Battery was dry inside the ups.this ups did not gave me any problem in the past year and still running in very good condition with backup time of 45mins with cpu and monitor only.
The service customer care is also very good.in last I found it very usefull to me .
