This is a dedicated personal security device based around a 900/1800/1900 MHz GSM phone and GPS receiver. With the press of a button, your loved ones can locate you at the bottom of a well and send you messages of encouragement—"Them rats won't bite you!"
Nice mix of form and function. The case is all organic and cool and the flash-tastic website is full of non-sequiters. The Personal Securer supports remote configuration via SMS or GPRS as well as direct USB connectivity.
UPDATE - Upon closer inspection, this thing looks really gross.
