PERSONALLY I THINK THIS IS GREAT FOR X-GAMES
or any athlete on extreme sports.
One big problem of this kinda devices atemp to be the limite users, usually just one. But did you read? YOU CAN HAVE 12 PEOPLE SIMULTANIOUSLY CONNECTED.
'Cant be more happier 'cause its multiplatform, you can have it in Android and Apple devices. Usually another problem 'cause most of this interfaces just work with Apple and it's a big issue for Android users.
It's amazing the possibility to get in contact as soon as posible if you get involved in an accident with the features of gps and conection by email and sms.
Pretty nice deal.
