It shouldn't be sold. It says wireless and you think it's bluetooth or something. It's an ancient Chinese design without instructions, without anything to tell you what it does. I'm sorry I didn't return it but on the other hand I felt sorry for the courier for the money I paid.

I bought it for the TV box of the same company. The truth is that many of the buttons don't do what they say and instead do nothing, which results in confusion and the need for the original remote. The touchpad it has helps quite a bit. It serves as an aid rather than an exclusive controller.
