Pros
I am using another microtek square wave inverter running from 15 year with no problem. So cheer to microtek.

Good price

Cons
Product lacks ups(uninterruptable power supply) which is claimed on box.
Also product does not providing 100 % sinewave as claimed its almost 90 % so still you can listen small humming sound coming from fan.

So overall if you want durable product with compromise technology go for microtek else less durable but better perfomance go for luminous zelio.

Actual watt is 1100VA (825 Watts) inverter, Good quality product as expected.

Fan is little bit noisy..

best price and service
