My folks are in their late 80's and live in a rambling old house. My Dad in particular is thoroughly wobbly on his feet. I live in the same village as does my brother and we see them most days and do the shopping and what not. I'd like to get them wrist alarms in case they need help when I'm at work or on holiday or whatever - Dad was initially quite keen but has gone off the idea after reading the leaflets I got them ... Any of you MN Vipers out there had any experience of these gizmos? I don't know whether to push it or not ...
