This product is a very useful way of ensuring somebody has help when needed - just at the touch of a button.....without having to buy or rent one of the Community alarm systems. It is easy to set up but before doing so you do have to make sure that you have Caller Display as a service with BT...but that is VERY easy to arrange and inexpensive. All in all a very worth while product that should be more widely advertised.
It was purchased as a Christmas present for an eighty two year old deaf gentleman. He is able to use the hands free operation without hearing aids and the large numerals are excellent for his failing eyesight.
