This Covert TV Clicker device is easily concealed in your pocket and can control 90% of TVs (including volume, channel and power).
The mini TV Remote will automatically search for the remote code. Just press and hold the mute button, and as soon as the TV mutes, release the mute button to lock into that TV's code.
You can then control the channel, volume or even turn it on & off!
