I received this today and personally a few things I don't really like: 1. The button's don't click into place even at the specified angles. It takes multiple adjustments back and forth before it clicks into place. 2. You have to adjust each of the six dial buttons one by one. It would make sense if your could adjusts the corresponding one on the other side simultaneously but the arrow on the button get covered up with by your thumb and you have to look at the dial front on to see the angles 3. The picture on the instruction sheet could be better. It's hard to tell what angle the laptop support panel will be. So you have to try each of them one by one, through trial an error. 4. There's a bit of a noticeable wobble when typing and the legs slide across your desk, as there's no grip. (See Bottom position configuration, first image)
It seems like it might be good for reading in bed or on the sofa but not at the desk. I'll continue trialling this today but I'll most likely return it.
