The fasteners are made on your desktop. Do not worry, you can either break through the wood of the desk to fix the arm, or if you want to preserve your office, you can just use fournises clips.
I used the pliers. And I must say that the screen is incredibly stable. So much so, that if I let a big book down on my desk, the screen on the Ergotron foot stirs unless my other screen on its original fixed foot.
This frees up the space used by the foot on your desktop. I now + 30 cm free on the bottom of my desk.
The arm movements are very pleasant. Without tighten the screws of arms, resistance to movement is perfect.
Just enough to not only the weight of my 24 "screen will do it little by little down (once in place, the arm keeps the screen perfectly placed, even if it not hit for weeks) and just enough the small resistance is felt when moving the screen, without one must force to move it. It's just perfect.
The arm also comes with a system for the screen wires are hidden in the interior of the arm and not dragged to the desktop when you pull the screen. It works very well, there are systems developed for + hide cables Ergotron but this did a great job, and simplicity that its installation is much simpler +.
The arm allows to move the screen up and down. You can touch with the office down the screen, and you can hop on +/- 40 cm in height. I do not think there have limit on the right and left screen rotation, I touch the wall behind the screen before reaching this limit. It can also be rotated to that instead of the screen is horizontal, it is placed vertically can be tilted forward and backward the screen (forward rotation and less free than other rear corners, damage) . And you can either pull the screen on a 80 cm has a meter I think. All this easily, with the pleasant feeling of resistance that supply screen, sign of quality.
In the end, a great product. He will not révolutioner your use of the pc if you are just a regular user. However it will significantly enhance your experience from day to day.
When I watch a movie, I just leaned back on my chair and I raise the screen while leaning him forward, to have the screen above me while I slept, my couch is close enough to quell the screen as sitting on it, to put the vertical screen is handy for reading some pdf, or to watch certain image (allowing the image to take a bcp + much of the screen) instead released under the screen is not negligible either. I now hidden under the screen a USB extension cable, the charging cable from my cell phone etc. it is better to have them hidden behind the screen than hanging on the side of the desk.
In the end my only regret is that my second screen is not VESA connector to install an arm on him.
