I use this Microtek Inverter from 5 years so want to share my views over this but that. It has very easy to use, even small child can learn how to use. It has automatic on fuction when power cut off. It has come with 3 year warranty and till date I have not face any problem in using this inverter. It is very helpful in hotty days because its backup storage of power is quite good and support various electronic components.
It gives around 12 hours power supply if we use average equipments such as tubelight, fan, mixy etc. Really I like it so much.
