I got this because I have a bad back and sitting is a killer on back pain. I only had used it for about a week or so now, so we'll see about the longevity, but so far I like. It sits fairly sturdy on my desk, though my monitors do wobble a bit when I type (maybe I need to type more lightly?). Adjusting the tension to be just-right takes a while & will need to be readjusted with any changes to monitors, etc. It's super easy to adjust the working height (again, you'll need to adjust the tension to get it just right). If this stand lasts 10 years or more, then I'll say it was worth the price, but if the tension system fails in short order, then I would have to reassess the purchase--guess time will tell. One very annoying thing was the enormous MOLDED STYROFOAM pieces used to ship this product. I've never seen such huge pieces of styrofoam before! It seemed excessive and I felt a combo of less foam and some rigid, shaped cardboard would've been sufficient. My city doesn't recycle styrofoam and it was a pain to break it down to get rid of it in the trash (otherwise I would have to pay to throw away the styrofoam monster!)
The Ergotron 45-245-026 mounting arm is made from quality materials for the most part. It is sturdy and has a substantial base which leaves you confident that it'll hold the 2 monitors. You'll need at least 6 - 10 inches from the back of your desk to the wall to be able to use the full motion of the mounting arms.
This product is great! I have set up 1 full arm, as well as 1 short arm. 24 and a heavy 21 sit nicely atop the mounts. It looks very classy, and professional. We have arms at work and I was like I hate my stand I want this. Top quality metal, the arms weigh more than the monitors! I feel these arms could handle some tv screens and still be great, just remember you need clearance on the back end.
I have had the older Ergotron single monitor arms, but this one does not have a locking system to hold a monitor in place. It uses a spring-loaded mechanism to counter the weight of the monitors. Since I was using 2 Dell 2007FP's with 1600 x 1200 resolution - these are apparently too heavy for such a mechanism without a hard locking system, so beware. I managed to support the arms by using hose clamps over rubber tubing to solve the problem - unsightly, but it works!
