Don's buy any accessories in The chennai mobiles, all the accessories are local brand and they will tag their own higher price MRP Stickers. Recently purchased tempered glass for S7 edge, they given "In Base" company's tempered glass which is local product and it is available in local bazar for cheap rate.
They sold it to me for 1200/- Rs. Not at all worth, it is not stick properly with my mobile and touch quality became worst. Need to press hard to use touch screen. So 1200 Rs absolute waste for me. All the accessories they selling is local product. Please beware and don't buy any accessories.
