I had purchased Microtek Inverter UPS SEBZ 850 VA 4 years back which is still working fine without any technical issues. I am using it to power 2 fans, 4 LED lights, television and my desktop computer and it provides fair amount of back-up to these appliances. Its switching during power-cuts and resumes is so smooth that it never trips my television or computer in this process. My desktop has no separate UPS and I totally rely my Microtek inverter. Its operation is very easy and user friendly. LED lights are given to indicate current status of it operation. I strongly recommend it to my friends to get seamless power supply in their homes.
