Memory Minder - recordable (Cranbrook TN17)

Defender Memory Minder MKll - I bought this when my husband’s Alzheimers was advanced. I used it to trigger a voice message if he tried to leave the house alone. I don’t think it helped out particularly - it used to confuse him, and not long after, he died (not in any way related to the Memory Minder). That was 8 years ago and it has been in the back of a drawer ever since. I don’t know if it still works, but no reason to assume not. It takes 4 x AA batteries. Might it be of any use to anyone? Maybe a reminder not to forget keys, or whatever? I am in Cranbrook, TN17 3BY. Please contact me if interested. Jenny
