What owners single out
In their words
“I have sworn by this alarm clock for the last 10 years. It has been a game changer in my life and how I wake up. I swear it has never failed me. But it’s hard to convince others due to the price point. But I struggled with loud alarms. I even had two in the room and it never helped. Saying that, I think it’s time for my next one.”

“I love this clock so much. It is one of my favourite appliances. It is a joy to wake up to the sounds of birds and the sunrise. So I was devastated when at about the 3 year mark it simply stopped working. Won’t turn on at all. I unplugged it for about a month to take it to the recycle depot when I thought I would just plug it in one more time and confirm before parting with it.”
