I bought mine used from eBay. Tools needed was a Phillips head screw driver and size 2mm and 3mm Allen keys. Installation instructions that comes with it is comprehensive enough. This M2 model is good for any flat panel monitor up to 20lbs beyond which Humanscale recommends the heavier duty M8 model.

| Figure 1 Fitted supplied VESA plate to rear of LG 34UM95 monitor. Find 4 extras screws or 2 in the case of my LG as I can reuse the 2 from the factory mount. |
VESA plate comes pre-drilled for 100mm and 75mm spacing. Figure 1 shows VESA plate screwed onto back of LG 34UM95 monitor. You'll need find 4 extra screws that are of the right size and length to secure the VESA plate. The VESA plate will slide clip onto the top arm end and locked via a spring retaining tab.

| Figure 2 Comprehensive Manual provided. Arm components are finished beautifully and solid in construction. |
Figure 2 shows the two arms with large pins at end. Of note is that the pin that fits into the desk table top clamp has two grub screws in the recess to prevent full rotation when secured. I had them removed! Didn't need to restrict rotation for my case. Top monitor arm has two flexible cable clips for routing monitor cables neatly.
In my eBay purchased arm, I was missing one plastic clip at the table top clamp but it didn't matter much to me.

| Figure 3 View of completed install. My unit was missing a cable clip that attaches to the desktop mount bracket but it didn't bother me. |
As mentioned I removed 2 grub screws in the pin that fits onto the Desk clamp top as I wanted full rotation capability.
The adjustability comes from 6 points: 2 horizontal rotation from both lower ends of the two arms, 2 vertical(up-down) rotation from the upper arm which are spring loaded with frictional pads to produce smooth movements and 1 more rotational joint and 1 swivelling joint at the other end of the top part of upper arm where the VESA plate connects to the upper arm. These just gives very good flexibilities in all desired positioning of the monitor.

| Figure 4 10-inch lift from bottom of monitor is cool! |
Gives me a good 10-inch maximum lift with 3 dimensional rotation (as long as monitor doesn't hit arms at the back or anything around!), fore-aft, up-down freedom as compared with maybe 4-inch or so of the supplied monitor leg with limited angle adjustment.
Needless to say, lowering it flat onto the desktop is no problems at all.
Even rotating my ultrawide LG 34UM95 to a portrait orientation is easily accomplished.
Retention stability at any position can be adjusted by screws to tighten friction via contact plastics on various parts of the arms. Adjust until movement is smooth and without binding. See instruction menu.

Highly recommended.
