1.[Concentrate on the time]This electronic calendar alarm clock is designed to help people who are visually impaired or poor vision to pay attention to the time, especially the elderly and people with Alzheimer's disease, which reminds me of my grandmother, she needs such an alarm clock to help her understand the time and live a better life. It's a perfect product to give them as a gift. 2.[8 inch large screen]High quality screen. There is data display in pure white on a black background on the high quality 8 inch screen where there is almost no smudge, making for exceptional readability from every viewing angle. And the numbers are large enough for easy viewing from the office, classroom, or living room, allowing seniors to see the time clearly. 3.[Very practical]In addition to the time, which can be read in 12H or 24H format, it displays the date with the day, as well as the temperature and ambient humidity. It has three alarms, practical if there are several people using it.And it features 1 hanging holes and a kickstand, can not only be placed on the nightstand, but also hung on the wall. 4.[5V1A adapter] It's powered by a 5V1A adapter(NOT INCLUDED), and the built-in battery saves you from having to reset the time every time you lose power. It works on power and you can adjust the intensity of the display on three levels. There are no ticks during work (except the alarm time) and it helps you get a deeper and more restful sleep.
