Ok, so you walk into starschmucks and get your double half Mocca choco latte Ya Ya, Creole Lady Marmalade to go
and 5 miles and 700 mg of caffeine later you realize you've gone and left your $800 phone on the counter. Oops! Good thing you have insurance on your phone. Wait, the debil you say? No insurance. SOL!
I'm suuuuure it will still be there! In this honest city?
Ok, so forgo all that nightmare and get this cellphone-child-minder. It will beep when you're out of bluetooth range.
Shipping is $5.24 (YMMV)
It doubles as a bluetooth speakerphone/ "Help, I've fallen and cannot get up!" button if you hold it for 9 seconds, help will come.
It will flash and vibrate if you get a call within its bluetooth proximity, also.
