Voltas is a brand made by tata. I like it not too much but it is not too bad also. one thing what I would like to appreciate is its pricing. it is good enough in performance. I am not satisfied by its after purchase services. the customer support team should be some experienced and commercial. they should also polite too. truly speaking it is satisfactory experience with it. some miner defects may be case specific. also I didn’t used a branded stabilizer it may be a reason of its misbehavior.
