Review: Hard to find but worth the trouble - I ordered this phone because it was set up for the digital charge over. I went for this model as it has an amplified ringing tone What I am really impressed with is the slow button This slows the callers speech without distorting it Which is a boon as so many call centres have agents that speak to fast or you can't understand what they are saying. Or Both. It is an expensive unit however it can be found on promotion if you can wait and look around Take your time,it is worth it.

### ⭐⭐⭐⭐⭐ Loud ringer and easy to set up
*by H***N on 4 November 2025*

My dad is very hard of hearing. These phones have a very loud ringer. The base phone/unit and the additional handsets were very easy to set up.

### ⭐⭐⭐⭐ Very nice, just too heavy.
*by B***. on 23 August 2025*

The phones are sadly too heavy, which is not great with my arthritis, but the rest of the phone functions are brilliant. They're very solidly put together, I just wish they'd made then a bit lighter, that's all. The sound is good, and the hand-free is very clear, Age range, I'd say for older people, but still too heavy, that's the only negative with the phone.
