At first, when I bought it from a well-known online store, it worked immediately after a few seconds. I took out the batteries and left it aside for months. When I put in new batteries again to use it, it didn't work and was unresponsive; the TV wouldn't even turn on. Cheap construction regarding the buttons, but for the price, you can't ask for much.

It is of very good construction, you don't need to do anything at all to connect it to the Samsung TV, it connects directly, just if the TV has the sports function, the corresponding button does not respond, all the other buttons for the TV's functions work perfectly, it's worth the money and you don't have to wait to receive it through foreign platforms...
