This arm lives up to every one of their feature claims and then some. Here are some of the standouts :- It's precision engineered and solid- It's sexy looking- It's American made (any company that is hiring people HERE to make innovative and quality products gets a *big salute and a bonus)- It's adjustable to almost any angle you could possibly make use of, and- When you maneuver it to the spot you want - it STAYS- But when you want to quickly move or simply adjust it to another spot, it smoothly swivels there .. and STAYS- And all of this even with heavy monitors - like my Dell 23" touchscreen.For work I put the arm attached to the back of the desk behind my laptop, and the DELL hangs nice and solid above the laptop screen for a perfect dual screen setup. At my height (6'3") that puts the big monitor right at eye height. Perfect for design and development.I push the laptop to the side and swing the arm all the way down to desk height in front of me for DJ'ing with the touchscreen. And I easily swing the arm with the DELL all the way around facing my bed if I feel like watching a movie at night.At no time have I doubted that this thing was stable or that my heavy monitor was in any way at risk. Nor is it the slightest bit finicky about moving or staying where I put it. It smoothly and precisely does its job and does not need adjustment at the joints in the slightest.Now about my experience with customer service:The assembly is basically simple, so the 1 or 2 page sparse instructions were good enough for me to get it 90% there. However the last thing that was holding me up mounting it and finishing the job, was the 'pan' motion left and right (like shaking your head motion left right).All of the other directions of motion have either hex bolts for adjustment, or a screw, or they don't need any adjustment. But the pan left/right was stuck. And I couldn't find any adjustment for that axis of motion at all.When I called the company on the phone somebody picked up after minimal hold. Lo and behold if it wasn't someone living and working right here in the US! After I briefly explained the problem she said she had never seen that before, and she took my number to have someone call me back as soon as they got in the office.Well the next morning I got a call from someone who immediately and helpfully fixed the issue. He said that axis of motion did not need an adjustment. I grabbed a can of spray silicone and a couple of shots on the axis bolt and it was working great.I had a feeling this guy was in management at the company or possibly the owner. He was really friendly and concerned that the unit was working out as advertised - he was also intimately acquainted with the engineering of the arm.Anyway, I purchased some great products in 2013, but this desk mount arm is my personal Product of the Year. In fact, I like it so much that I just ordered one of their laptop stands. With the quality of the arm I already own in mind I'm sure its just as precision and solidly built.

I ordered this on Wednesday afternoon and selected the super saver shipping option (5-9 days), so I was pretty surprised when I got home the next day and it was sitting on the door step!The stand is nearly perfect. It took about 20 minutes to install. The only tool required was a small screwdriver to remove the mount from my monitor (It's a Dell 2407WFP, by the way).My desk has a glass top surface (on top of wood), so I was worried about the stand scratching the glass, cracking the glass, or not getting a good fit against the glass. Luckily, the base has rubber pads so that it grips the glass very well without scratching it.The build quality is excellent. The parts are weighty and feel solid. The monitor moves around very well and has quite a large range of motion on this arm. One odd aspect of the installation is that the 2 articulated arms are not bolted together in anyway -- each one sits on top of a plastic flange and is held in place just by the weight of the monitor. This sounds like a shaky set up but it works out nicely in practice, although there is a little bit of play around each flange (given that they are not manufactured perfectly).The one drawback is the cable management system. The lower arm (which is optional) has a removable cover and is hollow so that you can route wires through it. However, neither the base nor the upper arm has any built in cable management. Seems weird (to me) to have the capability only in one part (and the optional part, at that) and not have it in the two required parts. Even weirder, they include 2 cable ties in the box so that you can cable tie your wires to the upper arm to hold them in place. This was the option I chose, and it works fine, so my rating is still 5 stars, even though it is an odd design.I was able to get a couple square feet of usable desk space by using this arm instead of the standard monitor base, plus I can now swing the monitor around to watch movies from my bed (it's a weird angle -- the room is L-shaped), and to top it all off, I got overnight delivery for free :) Highly recommended.UPDATE:After using this for several years, I still love it. In fact, I just ordered a second one to go to a dual-display set up.When I moved a couple years ago, I lost the plastic flange that fits inside this arm. I emailed Ergotron to tell them about this, and they mailed me a new flange for free. They didn't even charge me for shipping. That level of customer service is so rare!!! I'd give 6 stars if I could.
