Conveniently with some reservations

the advantages:
+ Price
+ Maintenance
+ 2 joints

Disadvantages:
- Monitor hangs slightly askew (depending on which side you push back him)
- Monitor wobbles slightly
- Trim is not very nice, not fit and knartscht
- Mounting plate on Monitot concealed a connection

Generally one can say that you get a passable Wandhalgterung for the price.
However, the holder is not for permanent use (adjustment) is recommended unless you can trim off the.
The covert plug does not bother me, and this problem is different from monitor to monitor (I have the Samsung Sync Master P2770HD)
