It is quite unstable, especially if placed on a table or a hard surface, it moves quite a bit and creates a feeling of insecurity, especially if it is a heavy laptop. It has several positions and heights in which it can be placed and can stand in various ways, but overall it does not inspire confidence as it "plays" quite a bit, especially in a high position (e.g. on the floor)

It is very convenient and quite lightweight. Good construction with many options in several positions. To achieve better support, it should be placed in a more stable spot, or else it needs a wide couch so that it sits more correctly and does not move.

It is very functional on sofas and in the office. However, it is not suitable as a floor base because it is short.
