I don't love this stand. It is very difficult and time consuming to adjust. There are a total of 9 black knobs that unscrew to adjust the height or position of the panel. I have a hard time getting them unscrewed and also getting them to screw back into their hole. I also had to make modifications to the stand because the panel wouldn't stay level in a horizontal position. I do tend to mainly use it in a horizontal position for comfort and not wanting to fuss with adjusting it. But this is the cheapest panel stand I've found from anywhere so I have to give them points for having a more affordable stand. I did give my feedback on things I felt could be improved and that was passed along to their engineers. I did also look at their other more expensive stands and think those stands are much better designed. If you plan on adjusting the stand often I think getting one of their other stands would be a better choice. If you plan on using it in a fixed position this stand should work for you
