I m mayank from ambala cantt I want to share my experience of using genus sure sinr wave invertor I had read many peoples review that this invertor is good at first but after that its not . But guys I m using this invertor for 8 months and I m not getting any problem last to last day I had vent to my frnds house there his invertor was making too much noise then I realize that the best invertor is genus sure sine wave invertor which do not make noise like others .
