Although the thing looks funny, but keeps the TV as a picture on the wall. The cables can be hide behind well. Depending on whether or not to use shims is the distance from the wall is 1.5 or 2.7 cm.
What does bother me, however, that the description should be used exactly which dimensions are not specified. Since the device so then depends on the cable between the two attachment points, it is possible that too not measure accurately. The description indicates that you should use a distance between the attachment points 18 to 20 cm, thus the device will depend a little higher or lower. My device hangs now but a few centimeters higher than planned even though I had everything accurately measured. I will now, willy-nilly have to be so if I do not want holes again the wall.
