Psst. Hey, buddy. Over here. Did you know that people are spying on you? Yes, even as you read this there is probably a hidden audio recording device nearby just waiting to pick up whatever you say. That recording can then be used against you in any number of unscrupulous situations which I don't even want to go into. You've got to protect yourself!

This Audio Recording Device Blocker is perfect for your needs, my friend. It emits a constant tone that, while inaudible to puny human ears, totally screws with recording devices. Those weasels might think they've got you on tape ordering a Quarter Pounder with Cheese, but all they'll end up with is a garbled mess. That way your ordering habits will never be used against you, and that's what's really important. — Adam Frucci
