Not as good as the old LX model

I have two Ergotron LX-arms in use for years, mind you the old model (45-179-194). These are a must for a good computer workstation. Now I have bought two arms of the new model (which offered here in Amazon) and found out that the stability of the poor has deteriorated considerably. Wobbled earlier 22Zöller actually not that new arms are not as stable by far and the whole system swings after moving even after quite strong.

So if anyone has an old arm and believes that the new just as good, let him be warned, the new is not as stable by far. I would therefore recommend a wall bracket so that the vibrations of the table are not transmitted to the monitor. Since the wall is stable, the less stable support then does not bother so much.

All those who will be using the new well fully satisfied not know the old model. Nevertheless, I give only three stars because it just wobbles too much and recommend the wall mount or mounting on a solid desk. With a robust table not the part is not recommended.

Ps .: FYI. For a 30Zoller I can no longer use the new model. The old works fine after a slight modification of the spring which is responsible for the tilting of the monitor. (But is not a drawback because the part is not built for 30s.)
