I bought this phone for an elderly relative who has sight and hearing difficulties.
First I had to help her with the phone set up because she could not see the instructions on the phone screen face to find the different functions, the letters and numbers are hard to distinguish, this also makes it almost impossible for her to check the number she inputting as she goes along.
Though the number buttons are large and clear there is not enough clarity made to identify the green on button and red off button for someone with poor sight.
The incoming ring sound is not really loud enough even on the highest level.
The speech sound is excellent especially when the sound booster is used, though the button for this on the side of the phone is a bit fiddly to use for someone in their 90's.
Overall the Doro is better than a regular phone but there could be lots more improvements made to it to make it more user friendly.
