All screens must be (head up eye level) to be healthy.

So your idea of healthy is to hunch over and look down 45degrees to the tiny laptop screen. Really...

By far the worst mobile computer work table I've ever used. The height is too low if you need to stand and type. The mouse pad tray is too loose to use, as it will swivel out from under your mouse when you move it. After having to use one for a few months the screws began to fall out from the bottom, causing the mouse pad, cup holder, and bar across the back to all fall off. Not that they were much use anyway. Over all it is small and chintzy, but by far the worst thing was its limitation in height, causing me to have to stoop to see my screen causing neck and back pain. And I am only 5' 8" tall.
