Very lightweight and comfortable for reading or computer settings but complex and not logical and austere colors.

This ultra lightweight support is very stable and very convenient to use his tablet or laptop lying recumbent or possession either in a bed or on a sun lounger.
But I also often serve to read, especially for a little bulky books, she is ultra adapted for this use with its small ledge that holds the books.
I would make a small reserve on the settings. There are 3 settings on each foot, a priori well because the angles are indicated with small detents to the different measures.
By cons, it is absurd to have numbered the corners twice on each 180 ° circular slider !!! and not 360 as would have been logical.
Indeed, when you set the media to your liking, you store the angles of joints of each leg 3 before closing the whole flat for storage.
And while there, when you want to use it again, how to know if it was 90 degrees in one direction or the other on the first junction or 120 ° in one direction or the other on the 2nd junction and well now, suddenly, you pay as you thought in the previous use and you end up with an unusable contemporary sculpture.
In short, it is not logical ...

I have not used the computer fan so I can not comment.

The manufacturer may also propose small cool colors for the metallic gray or black, blah!
