21430 : robust, stable, well designed

I use it for conference calls - 1) to use a handsfree mic instead of a headset and 2) to free up desk. This is probably not the intended purpose but it works well for me.

The stand is very stable. If the counterweight is properly positioned, the mic arm stays in balance with very little tightening of the screw handle.

When the vertical bar is in its lowest position (~ 1m 40 cm from the floor - about height level of a person sitting on a chair), the horizontal arm can be moved around 365 degrees with the castors fixed. It can be fixed with the vertical bar screw if necessary.

The stand takes up some space but can be used at home. If used at home, it is a good idea to place it near a wall and not in the middle of a room.

Overall this is a top quality product. I find nothing wrong either with the design or the materials.
