Portronics have cheap products. Those work for 6 months or nearly 1 year. After which you cannot claim the warranty. When you have the option to claim the warranty too, you got to send the product to their warehouse and you have to bare the courier charges. They do not have service centres in any of the cities. Please do not buy any products from here. My keyboard and mouse not working. And the earphone I bought from here too stopped working in 7 months.
