This device is so small it is easily concealed in your pocket, it's only 1½ "x 2½" x less than ¼" thick! It can control, volume, change the channel or turn the TV on & off. Just imagine the fun with this at a party, or the lounge at the doctors office. The mini TV Remote works on 90% of all TV's. It 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!
