I have a similar fake-sunrise alarm clock (a Lumie Sunray). It does tend to wake me up in a slightly less jarring manner than a beeping alarm, and the night-time fadeout makes me (mildly, pleasantly) sleepy when I'm not too impatient or too late to bed to wait for it. I haven't, however, noticed being any less grumpy or more awake/better rested.
If it broke would I buy a new one? As an alarm clock or SAD remedy, not out of my own pocket, but I find the fadeable bedside light useful on its own. Not £50 of useful though.
(The light doesn't always wake me, either, so I have to keep the backup beeper on. But I tend to sleep facing away from it with my head under thick dark sheets - not because of the lamp, habit built up over many years - so that might well be why. I usually wake up enough to turn the sound off before it goes anyway.)
