I am interested in Valkee and recently ordered one to see if it works. My depressive periods often begin december and last till may. I have followed this site among others since 2011, and expected more responses and reviews from people after a year. According to Valkee they have sold around 10.000 units, but where are the positive/negative reviews online - from blogs, social networks and other sites giving it a try? Don't get me wrong - there ARE reviews, like the ones above, but they are really hard to find among all marketing shit going on when doing a google search. I don't even find any forum among SAD people where the product is tested and discussed. The Valkee facebook site is not flooding with comments, they are quite sparse. This makes me a sceptic, but well see. In a few weeks I can tell if it works or not...
