I have really struggled with SAD for years so I boughtthis for myself for Christmas this year. I LOVE IT. It's bright, but not too bright. It's not even as bright as I expected it to be. I switch it on at my desk while I start my work day and find that I don't want to turn it off after an hour because I enjoy having it on. I do feel that my mood is lifted. Normally, by mid-winter my depression is severe, but not this year! Of course, I am doing other things to mitigate my depression, but the light is helping. It is 100% worth the cost. As for the design, it is stable sitting on my desk, has two light settings, and comes with an additional light sheild to lower the intensity of the light if you like (which I don't recomend). I have not, as yet, tried to travel with it; but it is lightweight and simply plus into an electrical outlet. It is flat, so it would be easy to transport in a laptop bag, backpack, or suitcase.
