SeniorSafe GPS is another tracking/alarm/communication device for the elderly and can be obtained from IntelliTrac Imagine

It also provides tracking, and the ability to make some calls from it.
The company claims that the running costs are low, but it seems to me that it would cost $300 per year to run and $499 to buy the unit. If this is low cost, how much the other devices cost?
For those of us with kids - there is also a model for tracking your kiddies without call-out options. Not sure if I like the idea.
