A good Digital Mirror Alarm Clocks, it can work on mains or batteries. When running on batteries, the watch goes into sleep mode to save battery power.

Although the clock is rather small, the displayed numbers are large and bright, easily visible from a distance. Feature wise, it's rich, displaying year, date, temperature, and time in successively. Initial setting is a bit tricky but easily mastered. I'm very happy with the purchase and highly recommend it. BTW, Shopper Plus excellent customer service is commendable.

It is USB and battery powered. Remains on and visible if USB is plugged in. Can be dimmed. Fits nicely where I need a clock on my desk

Just perfect.

Very useful when waking up during the night to see the time easily, even with the clock's low dim setting.

Très satisfait
