Today I have share my experience about this Kten company's square wave inverter called Kten Marathon Inverter 950 VA Square Wave Inverter.
I brought it before 4 months and after two months means two months ago I observed some disadvantages in this square wave inverter like reduction of power or reduce in the durability quality and also less backup.
Kten company was not compromising on their customer satisfaction but in case of this inverter he was compromised.
And hence I give only two stars for this Kten Marathon Inverter 950 VA Square Wave Inverter.
So think before buy.
