It's my first wake-up light and it seems to be excellent at that function. However, it also seems a little antiquated in some of its limitations.
1. There is no battery backup so if power goes out it loses the time. 2. There is no 7-day schedule, so if you want to get up later on a Sunday you have to set it every Saturday night, then set it back again every Sunday night (it will remember 2 wake-up times). 3. The built-in sounds are good, but they're just sound files. Why can't it play mp3s? In addition the speaker hisses badly at anything above half volume. 4. The radio is only FM, not DAB. That means you get a choice of 11 stations all playing bad pop music. 5. The product has a sleep light, which starts dim and gets dimmer over a short period of time. You enable this mode manually, but sometimes instead of turning on at the preset brightness, it turns on at full daylight brightness. This is far from ideal and only serves to wake you up at bed time.
I suspect most of the above limitations are due to insufficient competition in the marketplace. Maybe someone will make a replacement circuit board for the device that fixes all this. The light itself is excellent, the device is easy to use and it looks great. I got the 5-sounds version with the red-to-yellow light.
