A 59,00 dollar (about 40euro) teasergun is available in USA.
The model is quite a copy of Sony Ericsson W800, however it does have not any function releated to the phone.
For the price you'll receive the teasergun, 3 CR2 battery, a leather case with clip to safely store your phone.
It features a 950.000 volt shock, and a bright light with multiple leds.
Comes with two saftey key's, so you can't shock yourself when put in your pockets.
The idea behind this 'teaserphone' is when struck by an attacker, they are quite aware you might carry a weapon to defend yourself.
Since they are after your wallet and other value goods they might like your mobile aswell.
When you pull-out your shocking-950.000 volt-w800 they be fried like a small fly on a toaster.
I'm curious if SE is going to include this new feature in upcomming releases
