Solid, quality, easy-to-assemble monitor mount (plus a couple assembly tips)
I struggled to make the decision to buy this. I read several online review articles on monitor arms, then looked at many products on Amazon, reading the buyer feedback. Even the purported top brands had several very nasty 1* reviews. These were not just mildly disgruntled customers; they wrote whole essays on all that was wrong! I despaired of finding anything I'd like. I finally decided to go for a mid-tier priced item. I called Huanuo tech support with a question just to see how responsive they were, and they were great. So I decided to purchase this item. Though time will tell if it holds up, my initial impressions after unpacking and installation are very favorable. The item was packed very securely in a protective cardboard tray in a box that was inside another box, so arrived undamaged. Build quality is excellent, and all the parts are heavy-duty, not flimsy at all. I trust my monitor will be securely held in place even after multiple swivels. I bought it for a sit-stand desk I built; this will allow me to swivel the monitor into position where I sit, then swivel it over to where I have a walking treadmill. It works perfectly for that! It is a little stiff for tilting the monitor, but I prefer that to having it droop or otherwise change position, which it does not do. Assembly instructions were mostly pictorial, but easy enough to understand. All tools necessary for a c-clamp installation were supplied. (If you plan to use the bolt/grommet installation method, then you need a drill and drillbit to make the hole in the desk.) I have just one tip to share regarding the instructions, where it was not clear. On Step 3-2 where you attach the monitor connector to the monitor, it says that "the connector pin should be directed toward the top of the monitor, and has a diagram with a finger pointing to the pin itself. However, this will result in an upside down monitor. It should say the "pin assembly" should point toward the top of the monitor. The pin itself should point towards the bottom. If you study Step 4, you'll understand how it must be mounted in Step 3-2. My Samsung monitor has 75mm VESA holes, but they are in a recessed circular area that the mounting plate is too big to fit into. I added a couple washers between the monitor and the monitor mount, and then everything worked just fine. Overall, a really nice piece of equipment, reasonably priced, and I expect it to last a long time. Customer service was good the one time I called with a pre-sales question.

Well-built and study monitor arm
This monitor arm is fairly easy to set up and very sturdy. Monitors are easy to move after being attached, but there is a bit of tension that keeps the monitors from shaking. There is a cable pass-through in the base of the arm, which is convenient. The wire management system is pretty well designed, although I needed to purchase longer cables to route them through the system. I use two arms for a dual monitor set-up. It's important to note that the two bases need to be placed far apart to align monitors properly. Clearance is also necessary behind the desk. Overall, this is a great product.

A very solid and sturdy monitor arm. I bought 2!
This monitor mount is super sturdy and made of thick high quality metal. Itโs super easy to adjust, and really instills confidence that it can hold my heavy monitors. Iโm currently using a 32 inch OLED monitor as my main and this arm has no issues holding it in place with zero wiggle or strain. The added usb port in the base is a great touch, allowing me to connect my mic from across the table to my PC. Installation was quick and simple, all the pieces came in the box along with the appropriate tools. Worth the price, and performed above my expectations. I bought 2 of them!

Works great and heavy duty.
Installed easy and quickly. I only wish I had known exactly what one looked like installed. I had to drill a very small hole in the desk , so much nicer looking than the clamp. I would have drill a little differntly if i knew it didnโt close to a zero point in front of the base and it Ends up several inches away or off center but that was more installation error then anything else. I did not know what i was missing . So much better then the stand. Definitely recommend .

Got me through it
Pretty good monitor arm. It was easy to set up and cable management that made sense. Adjustable tensioners which was nice. Once the monitor is on it, the stability is rock solid and let's you move it around how you need. Durable metal material and heavy. It let me mount my monitor to a bed stand for after my back surgery which got me through a lot of laying in bed.

Works perfect with 34" LG curved ultrawide
I have an LG 34" curved ultrawide monitor, and it works perfectly and supports the weight easily. It is very adjustable and stable. You can easily tilt, swivel or move up and down, and the adjustments are easy with the provided tools. I was tired of the stand of my LG monitor getting in the way of my mouse and keyboard. This freed up a ton of desk space. Also lets me move the monitor very close or very far depending on my needs throughout the day. I move the monitor around multiple times a day, and it has stayed very solid. Great value for the money!

It's doing a GREAT job!
I've been using this since late October, and it's now end of December. It's holding my Odyssey 49" monitor. I have a corner desk, so it's attached to one side (please excuse the mess back there - I'm in the middle of reorganizing). Firstly, the monitor is MUCH lighter, when you take it's original stand off, so I felt quite confident that this would work well. I was not disappointed. Having it attached at an angle does limit SOME of the movement, since the monitor has to be turned to view straight on from my desk. but it STILL has great lateral movement, excellent turning adjustability, and lifts up about 10" (at the bottom), for access behind it. I especially appreciate the ability to angle the monitor up and down, based on the position of the unit. I do a good deal of detail work, so I needed to bring the monitor closer to my face. It's original stand was so huge, that was impossible. With this thing, I can adjust it to about 18" from my face, on a DEEP desk, and can move it back, to enjoy watching media. My neck and eyes are SUPER happy with the flexibility of this device. Challenges: PLEASE TEST THE INCLUDED USB EXTENSION CABLE BEFORE INSTALLING IT INTO THE UNIT! I didn't do that. It comes with a handy cable to insert into it's cable management system. Unfortunately, it was orange, but the perfect length to hit exactly right at the base of the unit. In my excitement, I installed it, and it DOESN'T WORK! Now, I'm not about to take this thing apart to make it work, so I have to have my cabling tied to the exterior of the arm, itself. So, don't make my mistake! The arm needs some serious tightening. They provide a handy hex key to do it, but you need to pay attention to all the locations to tighten. I was able to turn them sufficiently by myself (although I needed help to get the mount accomplished - especially holding the monitor to put the pieces together). Note that I don't have a strong grip, or much upper body power, so ANYONE likely can do it - but do be attentive, or your monitor won't stay still enough. I've been moving and lifting this for 2 and a half months, and I haven't yet needed to re-tighten it. It's flexible, but firm. Aside from that pesky cable issue, I HEARTILY recommend this arm!

Solid Built, But...
This "heavy duty" monitor arm is ideal for monitors that are proportional in weight versus a bottom heavy type monitor that's on the larger side 43+ size. I used a 48" monitor and although the arm could handle the weight and tightening the tilt was possible, the downside is that there is no way to lock or tighten the rotation. I noticed that the monitor would rotate clockwise to where I had to temporarily place a small box under the bottom-right corner of my monitor. It's because of this that I had to return the arm the next day after setting it up.

Great strong quality
Great sturdy strong. Doesn't swivel around a large XY plane as much but still good.
