100% original official Xiaomi product. You will get the box only. I use the remote, adapter, and cable for another device. You can buy an adapter and cable for just 200 Taka, and a mouse for 200 Taka to use it seamlessly. Come to my place, test it as much as you like, and take it only if you are satisfied.
