I prefer waking up to classical music every morning. It helps me wake up in a good mood, it lets me focus, and it gets me thinking first thing in the morning.
However, if I decided to purchase an alarm clock that didn’t play music. I would choose this. Just because I would wake up laughing every morning (and that right there makes it the perfect alarm clock for someone with Chronic Fatigue Syndrome). I have no idea where to purchase it though.
