Now days inverters are compulsory because in delhi their is no information about electircity , whem it goes between a day and when it will comes. They cut power for 6-6 hours a day and some times more. Thats why we need a inverters in our home to save from power cut .
And for microtek I dont suggest you for it because it look was not too much good and the price was too high. For services I dont say anything.
But in our home we have luminous invertor the look is too good and the price is reasonable . service is too good . when we bought it they take the machine at home and set it. After its start working they ask us is its working or settle good or you need any changes .
Service people was also so humble and like we are talking to our relatives.
