Having bought one of these around four years ago, I now can't live without it. Mine has just broken due to an extended power cut, and I have just bought a new one. Whilst it is initially complex to set up (or seems to be) it's actually quite easy to get the hang of if you are reasonably technologically competent. This links into your own bedside lamp and isn't awkward or offensive to the eye on the bedside table. The only downside to this product is that it requires an old-fashioned lamp bulb rather than the modern eco bulbs, as the latter do not dim. That said, waking up pleasantly to the light being gradually switched on has been a total life-saver for me over the past years as I loathe waking up in the dark to some shrill beeping in my ear, which quite frankly starts my day in a bad mood. This way I am actually awake before the alarm, having been wakened gradually. The other nice feature is that you can set it to dim gradually and for me, I find it helps me to go to sleep quite effectively. All round, a fantastic product for those who don't like alarms and dark mornings.
