Guys dont go for other reviews as you all knew that everything in this world has pros and cons or in your words advantages or disadvantages , I would rather say just go for this inverter( advertise by Sachin) as well cpu too because it gives heavy backup and lots more warranty coverage as compared to other companies such as microtex or exide or amaron, I would rather give you a small information it cosumes less energy compared to exide and keeps you ecofriendly with saving electricity as well energy too.
