This Bluetooth alarm clock is designed to function like the alarms on smartphones. Setting the alarm is easy and intuitive. A hidden button at the bottom of the alarm setting makes it easy to operate. Press the top once to snooze, press twice to cancel the alarm, or press just once to activate the backlight anytime. When the clock is connected through Bluetooth with the smartphone, the date and the time can be synchronized with the smartphone, including alarms and ringtones settings, backlight adjustment, etc., all through an app.
