I have been using this inverter for last one year and I am Totally disappointed over it. It started to give me glitch after mare five months. I have complained to the company for about three times yet, there servicemen comes, check and go but my problem stays the same. It stops charging any time and it creates sound while in use. Sometimes I feel all disturbed with it. Its battery is very dull and it seems to be empty soon. This inverter sparks too sometimes, so I really miffed with it.
