Placed in the right part of your bedroom at the right angle, and set at the right brightness level for you (1-10), this really does work well at gently preparing your eyes (body) for waking up when the alarm goes off. You may have already started waking with the light. The alarm gets louder as it goes off too, so not too frightening. However you have not control over the alarm level or sound, which is our greatest regret. Believe you can buy newer models where you have some control over this - such as using your own sounds or bird song for example. That's our only gripe. But overall this has changed our lives in the morning, as we have to wake early and winter is impossibly hard. So impressed that our 9 year old daughter now has one and although it doesn't always get her ready for waking up, she now (two-thirds of the time) will be rousing or awake rather than us having to spend half an hour trying to wake her up.
