I bought mictotek inverter in the year 2015 and I found it really well and easy to operate.When it first come to my home I used to use it whenever power get cut.Its backup is good.Power using quality is so gud.And its indicator quality is user friendly.Microtek inverter is really good and I refer all my follower to use it.Whenever battery charging get low , beap starts to come and conveys msg to the user to stop it as soon as possible.So its a user friendly inverter and I really convey this inverter to use it and promote it as far as we can
