I bought it for my grandpa. It is a better way to communicate than with the mobile phone for him. He's already 83 years old and healthy (thank god) but doenst get the mobile phone. But the hey bracelet is easy to use for him. And if he sends me 3 touches in a row i know that he needs help so we also use it as a alarm.
Pros
Can also work as a alarm for old people
Easy to use
Strong, doesnt break
