It is simple and we have not had any problems so far. The display is big enough to see easily. In the time mode, press and hold the “set”key for 2 seconds to begin setting the time.

Love it so much,love the temperature aspect,and the cuteness of it. Fits in one hand. Bought it for my son to keep on his desk during remote school.

Operates on batteries. It shines upward. Bought this to replace another small battery-powered alarm clock.

Nothing about this clock is intuitive. The system of rotating through the various settings is unreasonably awkward and not intuitive. After much research and frustration the only solution is to remove the battery and buy a different clock.

The alarm is almost impossible to operate. There is no way to disable the alarm it forces you to pick two times a day for the alarm to go off. The manual only tells you how to set the alarm.

This product isn't programmed for 2020. It has the wrong date with the day and is not correctable. When you enter calendar date it gives day of the week for 2019, not 2020.
