It has been more than two years of this inverter in my home. Since then I have no complaints regarding it. It looks good , with a compact size. It also displays the battery time left which can be used. The voltage never fluctuates. During charging , it displays the time remaining to charge. In this price range , it is a nice product. As luminous is a trustable brand , I would consider going for this device without any further thoughts. Th service for the product is good. It comes with a warranty which is of adequate time. Overall this product has satisfied me in terms of functionality and features.
