The microtek imverter which I am having of 1000EB is not upto the mark. The performa ce of the inverter is competitively less than luminious branded invertors .The durability of this inverter I can sat that ut is somewhat not so great it gives very less hours backup and when we brought it first it was working fine but after 2 to 3 months its performance Lowered down so becausce of it I thinks this inverter is not helpful on long run of time.its ease to use is that the inverter takes how much electricity that much output is not given by him so .as the function are not so hard but for an illiterate person it can cause a great tension .so in my views I should suggest you not to buy this abd buy luminous inverter
