People are always losing their keys, their phone and remote controls. The Cell Phone Watchdog covers two of those (you’re on our own with the remote). This wireless watchdog sounds an alarm when you and your cell phone are separated by more than 30 feet. Slipped onto a key ring or clipped to a belt, the Bluetooth device will vibrate, flash its LED light, and beep when its paired cell phone is left behind. It also signals incoming calls, functions as a remote Bluetooth noise canceling speakerphone, and doubles as a piercing panic alarm with an emergency number autodialer. And it might also be able to make you sandwich if you ask nicely.
