### ⭐⭐⭐ Spoiled by one annoying feature
*by M***S on 7 January 2025*

We bought this as an emergency phone to keep in a holiday cottage. It does the job, except that it has an annoying feature that if you leave it in the cradle to stay charged in bleeps every few minutes to tell you it is charged! Hence, people take it off the cradle and it runs out of charge and then when it is needed in an emergency (such as a power cut) it can't be used. There doesn't seem to be a way to disable this function so we have had to get rid of them.
