This is a great alarm clock for using during the dark months. I managed to wake up 10 minutes before the alarm went off just from the room being slowly lit up. It was a bit difficult to figure out how to switch the alarm off, and I don’t recommend snoozing it as it flashes quite violently when snooze ends. This could be a risk for people with epilepsy. It also does not come with a plug, only a USB cable. Overall I really like this alarm clock.
