After much searching, and a huge amount of bother with a DAB version, this little box does exactly what it says on the tin. It is simple to set up, simple to change alarm times, you can turn down/off the backlight (so that you can actually sleep), it is reliable, and has a battery back-up so you will be woken when there is or has been, a power cut. It will even charge/wake you to an ipod/iphone if that's your thing.
The sound quality is fairly average, but if you need to be woken by John Humphreys in full high fidelity you may want to reassess some other aspects of your life. As a bonus this really does look quite good, it is clean, smooth and unobtrusive.
Overall, this does tick all the boxes; it's a radio/alarm for people who just want to know the time and be woken by the radio. But do look elsewhere, it's remarkable how nobody but Sony seems to cater for this demographic.
