I am carer for my wife who has Alzheimers and lives at home with me. I need to be able to leave the house for 3 or 4 hours from time to time. During these periods we have been using an Auto Dial Plus alarm and pendant but find it does not meet our particular circumstances, for instance it ties up the landline so that no-one can use it to phone in while the alarm is operating. I am thinking instead of buying a simple mobile phone that uses pre-entered contact numbers available at the push of one button. Does anyone have experience of doing this? The reason I ask is that it is only when the equipment is used that its usefulness or otherwise emerges - the makers tend to be highly opmistic! Thank you.
