As bugs go, the CX-008 Spy Ear probably wouldn't make it in the top divisions of international espionage.
About the size of a deck of cards, it wouldn't hide well under the fronds of a lampshade or behind a headboard. Emblazoned with pictures of radio waves, its purpose isn't exactly hard to discern. But it does have one thing going for it: just slap in a SIM card and you can listen into it from any cellphone.
The Spy Ear is, in fact, pretty much a cellphone itself, cleverly configured and loaded with more than two weeks of battery life. At $140, it isn't too expensive, though the law might have a fine with your name on it should you choose to misuse one.
