I bought this item after Google-ing about the winter doldrums (I live in London, England!) and found the reviews on this product to claim an increase in energy and to feel somewhat refreshed when waking up. Much to my surprise the claims are true! I love my light and think it's a great buy. I feel more energetic and generally don't wake up in a slump on these long winter mornings. I would most definetly recommened this product to anyone thinking of trying a dawn simulator. It is cute on my night stand and is easy to use. Even though the light is not majorly strong it is still nice to wake up to SOME light around your face.
I was torn between purchasing this Lumie light or the ever-so-expensive Philips brand and must say that I am glad I went with Lumie. There were cheaper options as well but it is true that you get what you pay for and I am happy to have invested the £60 to get this!
Definetly makes these UK winters somewhat bearable lol.
