As a mobile DJ, I always found that most lapotop holders were either poorly conceived, impratical/clumsy, or not sturdy enough, ot not stable enough, or taking too much space, too much time to fold/unfold, or too heavy, or difficult to move, etc...
At last I found the right mix of sturdiness, ease of use, adaptability, portability, small footprint and stability I was looking for.
This thing folds and unfolds like a dream, it's very sturdy, takes very little space in my luggage, has a very small footprint, and is incredibly easy to setup.
The stability is very good, but not its strongest point. It depends on how you set the angle(s). It can be very stable in some positions/settings, or it can be not-so-stable in other positions/settings. It's up to you. But it's rather easy to find a good compromise.
Someone somewhere gave a lot of thought to the conception of this little gem. Thanks to him/her. If only such ingenuosity was used in all DJ equipement. My life would be so much easier...
