Simple and functional 15

I am using this medium for several weeks and I'm happy. This allows for the above laptop screen and keep your back as straight and neck. The keyboard that I added and connected USB is more comfortable than the laptop (keypad, larger buttons).
The carrier itself is relatively lightweight, solid air, and can be adjusted to different angles (which are sufficient).
The only downside would be the "edge" bottom who is there to prevent the computer from sliding, which can be a bit small. On my computer it's OK, but on larger ordis with a shape that provides less support on the front, it may be less convenient as less stable. But overall it's a simple, cheap and that is enough.
