Keeps the monitor, but also secure on the wall

The arm is well made, holds the monitor securely to the wall, is free to move in 2 joints. The hooking de monitor was easy, the provided material support many monitors and environments. The only slight downside for me is that the introduction of something stronger cable (eg HDMI cable) is very difficult in the cable guide. On the other hand the advantage that the cables are not easily slip out of the guide.
For my part, an unscrupulous buy recommendation (for 27-inch monitors)
