This anti-stress diffuser light to use during short days, I am puzzled. I struggled to find the right distance using a hand and support beyond 30 minutes of bright light diffused on the other. The benefits on mood ... you have to see over time. This object has the size of a tablet is sleek, comes with a pouch for storage and a patch cord to power a little short (50 cm more would be nice). Nothing is missing and it remains to verify its effectiveness. I will return to my review if necessary.
