Dekala Smart Sunrise Alarm Clock Wake Up Light Alarm Clocks for Bedrooms For Sleep. The multiple alarms function allows you to easily set four separate alarms, which can be used to separate weekdays and weekends, or to set different alarms for your family. And there's an easily-accessible snooze button in case it's still not time to get up, which gives you an extra 8-15 minutes of sleep; the music plays again after 9 minutes (up to 5 times). If you’re a heavy sleeper, this multi-alarm sunrise alarm clock will ensure you wake up even if the light doesn’t rouse you. A2
