Hawksweep Wireless Signal Detector Hidden Camera Tapping Device Cell Phone Bug RF Finder

Lacks sensitivity and frequency range that is advertised. No circuitry to prevent false readings, so you will get false positives (thinking there is a bug there when there isn't), and false negatives (not showing an active cell phone sitting next to it). It is apparently a generic Chinese brand, and doesn't have the Hawksweep brand on the unit, or on the packaging, nor is that model shown on their web site. Also, no instructions were included with the unit, though there are only two controls (sensitivity and a sound button).
