The best quality you could find. Yes price is not in an affordable range but if you want something to be reliable and simply does what it claims to do go with Lululook.
I also had an iPad pro 12 inch stand (which I returned when I returned when I returned my iPad)
The iPad pro stand is also very reliable and it also has one more tilting angle which is useful for drawing.
One small fact
In my experience, Generally I found the magnetics of s tab ultra stand more powerful than the iPad pro stand. The iPad one could be detach by heavy shaking (works well on day to day use without anything unusual), but tab s ultra stand is so powerful that even heavy shaking can not detach them.
Any way I would get another iPad lululook stand for if I again switch too iPad.
