I bought this based on other reviews. The only known mount option for the G9 Odyssey costs $400. I bought this mount as opened box for $70 making it quite the cost difference between the two choices. For other odyssey owners out there this mount will cover your needs, the reviews are accurate. However you will need to follow a couple quick steps.Before mounting the monitor, assemble the arms together on your desk. Be careful not to lose the little metal tabs between the arm shrouds they fall out easily when you take the arms apart later. Next take the provided tool and spend a minute rotating the middle of the arm adjustment screw towards the + symbol. You will question if the bolt will fall out from the amount of turns needed. Doing this is required or the gas piston won't hold up the monitor! Next the problem child of this mount is the vertical up/down tilt at the end of the arm. The included bolt won't hold the odyssey up and its a pain to deal with when the monitor is mounted. So trash it. Now take the heavy piston arm to your garage or hardware store. I found that a 13mm bolt head fit the hole and threads. Add a washer on both sides followed by a castle nut. You will need two 13mm wrenches or socket wrench to tighten the new bolt down, it won't take much pressure. Next reattach the arm onto the mount, without the monitor. Use a level or eyeball it to tighten it down evenly leaving the tilt at 0 degrees. Though it might be best to tilt it back or upwards 10 degrees due to how the arm mounts into the monitor bracket. Lastly mount the back plate to your monitor and attach the piston arm. If you're mildly strong pick up the monitor with the screen facing you then drop it into the mount on the desk. Really it's a two person job! If the monitor is tilted incorrectly you are going to need a friend to hold it or adjust it as you tighten/loosen the new bolt again, a major pain. I had it sitting on the desk and it was a thirty minute fight trying to get the tilt right. Turns out the mount itself on the arm tilts forward about 10 degrees making the monitor tilt down a little. Ughh just bring a friend the tilt adjustment is an all or nothing ordeal. Too Loose the monitor flips down and too tight it won't budge. It was terrible juggling this thing with tools in hand with this heavy thing... And that's all the extra work you need to do! Tighten the piston adjustment bolt towards the + and buy a new bolt for the vertical tilt.Oh pro tip: test without the monitor attached sitting down and see if you like the placement. Originally I had mine mounted center on the desk and well that didnt work at all. Now its off center to the right. Also use the included package foam to check clearences. I balanced the foam on the end of the arm and it worked great as a reference piece.As for mount itself, the mounting plate included does fit the odssey's metal cup plate, use the included black screws with a screw driver. Just be sure to tighten "everything" down. Don't skimp on this or locktight if you have it. Overall everything is thick aluminum or cast aluminum so its solid metal. The pressure plates are thick steel and well painted. Everything fit together without any extra work. The desk pressure plate is only held on top of rear vertical bolts by gravity. Its very jank but works the part when tightened. The plastic cable covers were a pain but doable.The biggest gripe I have is the janky L bracket. There are four thick screws holding it together and its not flush or a perfect 90 degrees in the back. So if your desk is against a wall like mine, it won't be the most ideal... I didnt add the plastic cover to save on an extra half inch clearence against the wall. I really dislike the screws on the L bracket. I had two of them strip out with mild pressure. In the future I'm going to redrill the holes and add proper bolts to secure it.The extra added effort was worth saving $300 over the other expensive option. I'll update this review if anything changes. For better or worse.
