I bought an IR line a few days ago, claiming that it can be installed 360°, no dead angle remote control TV

So I bought one, after all, it is not very expensive.

Then I installed it on my evpad 3plus TV box. This box has an infrared interface. The other end of the infrared, like the shape of a ball, sticks it behind the TV.

The remote control is really sensitive. Just point the remote control at the TV, you don't need to align the TV box, it is easy to change the station, and the remote control's receiving distance is also longer.

Then, I tried again, the remote control was not facing the TV, facing the ceiling, facing the other direction, it can be operated. Omg! It is too powerful!
