Review: easy for aging people - I bought this for my grandad, he's older and touch screen phones have small fonts and aren't easy for him to use. This flip phone is great, easy to use and has bigger buttons as he has always wanted a phone with large print and simple features. This is a perfect product and he is very happy with it. On top of that, it has an SOS for help function, which I think is very useful for older people, and this phone is great as a gift for elders.

### ⭐⭐⭐⭐⭐ Great phone , matches its competitor.
*by G***6 on 9 August 2025*

Easy phone to set up with contacts. Loud adjustable volume . Torch. Bold screen. Great camera Certainly a better phone and easier to set up than its competitor. Better price than its competitor. My 84 yr old dad found it easy to use , and could hear it ring .

### ⭐⭐⭐⭐ Ring tone is unchangeable, not very loud.
*by G***S on 10 July 2025*

There is no option to change the ringtone to a louder one. The factory setting one is not loud enough for anyone with hearing problems. Without my hearing aids, I can’t hear it. I struggle a bit with them in. I Googled how to change them, but the options shown were not available on this phone. My Carer will try again. All else is OK—great visible buttons.
