This one I did not know, but the reviews were okay and it is easy to see from use.
On the front of the release button which directly notifies the time. The voice acting minimally tinny, but is still very good to understand. The volume should be mentioned very positive for such a small device.
On the back there are three small rubber heads, which are necessary for the settings. "Normal" users can use it to safely arrange good, but for my grandmother that was suboptimal, as it has often accidentally pressed the buttons and thus adjusted the clock.
I have the buttons then cut off with a pair of nail scissors, so that they are no longer accidentally pressed and since my grandmother is very satisfied with it. The small clock, the other speakers Watches replaced about 90%, which it has otherwise in use!
The battery still shows no signs of fatigue.
I highly recommend this clock for visually impaired people in any case, as long as they have someone they once set correctly and if necessary the buttons a bit shortened.
5 stars are justified but mE
