Plus:
+ Emergency,
+ Genuine GPS, with remote configuration and monitoring via a website
+ Radio,
+ Keystrokes are read
+ Key lock is a slide switch
+ Flashlight (slide switch)
Minus:
- The radio only with inserted headphones as an antenna.
- After a somewhat prolonged pressure of about 1.5 sec the red "hang up" button is pressed, the phone switches off. That's just for seniors almost always the case and grandpa on hanging up the phone. Luckily, there are the keys, otherwise the phone in your pocket would be quickly turned off).
Conclusion: Very good idea with small drawbacks.
I have found nothing better.
