Very stable, swiveling to the side is very limited.

Mounting
Use the monitor bracket with a 12.5kg heavy DELL 30 inch monitor with VESA 100 mount. Since the VESA was 1.5mm in sunk screw holes 100 of DELL in the plastic cover, it required for each screw 2 additional shims to compensate for the height difference. The screws that were in the mount case could be used easily on the length of her.

Operating
The monitor mount is extremely stable, changes in position of the monitor are butterweich possible.

Why only two stars?
I have the perfect bracket mounted vertically in scale, then the monitor to hold exactly fixed so that although + -2 ° latitude are he hangs right in the middle. Now when I take off the bracket completely and put a spirit level on the monitor this is also perfectly in balance.
Schwenke I monitor but to the side, drops out a page. Say if I swing him around 80 ° to the right falls on one side of the monitor (30 "monitor size) to about 3cm from. The same is true when I swing it to the left.
Since untehralb of Montors the desk (who incidentally is in Libra), which falls but rather on.

My conclusion: height and depth can be adjusted without problems. Swivel (left or right) leads to imbalance of the monitor, the only theoretically correctable, are when the mounting screws that provide a + -2 ° latitude solved and screwed again after adjustment. I'd expect from a low cost carrier about 20 euros, but with a 70 euro bracket, which is actually unacceptable.
