Good for anti-advertising activists

Are you tired large mounted above each lane flat television bombard the queue with advertising?
Stimulates you a Commercial (construction / media) market especially in, and you want other customers (and / or their children) protect against the brainwashing?
Do you want to annoy your neighbors / friends / competitors?
Do you want to trigger the Außnahmezustand during the World Cup in the pub?

Here you'll find it :)

Disadvantages? Depending on the TV, it may take a few seconds in advance to the 'Off' signal hit (but is in the nature of things, for the producers anything). But a real disadvantage is the release button is too easy and often caught when wearing the thing on a key chain in a (jacket / pants) pocket. After a short time the battery dies. Can indeed be changed without any problems, but is still annoying.
