Great Dual Monitor Mount
Color: White-Mount
I bought this dual monitor arm desk mount for my wife’s computer to mount two 32” monitors. Unpacking and installation were fairly straight forward. The only two issues I had were: 1). Instructions state that this mount can be installed using a grommet hole in a desk to secure it to the desk. However, most grommet holes in desks (at least in the United States) are 2” holes. The grommet mounting option uses two all-thread bolts screwed into the base, but the outside spacing of the bolts is about 2-1/4” which, of course, is too big for 2” grommet holes. I ended up drilling two smaller holes in the desk, one for each all-thread bolt. On the plus side, this option secures the mount to the desk very securely. 2). There is no guidance in the installation instructions for optimal placement of the arm mount on the desk. I ended up temporarily installing the lower set of arms on the mount base and then experimented moving the base around the desk while swinging the arms to make sure they would clear all computer and other equipment on the desk as well as the walls. This method worked well and final placement clears everything while still giving full articulation of both arms. The unit is very heavy-duty and quality is excellent. Other than the two items mentioned above I am very impressed with this product. After installing this unit on my wife’s desk, and playing with it for a few days, I ordered one for my desk. Because of the two issues above I would give this 4-1/2 stars if I could. But these smaller issues are not enough for me to lower my rating to 4 stars, so 5 stars it is.

Great Looking and Sturdy Monitor Arms
Color: White-Mount, Color: White-Mount
I'm so impressed with these arms. They're super strong and sturdy holding up my 27" monitor and 34" ultrawide monitor. Setting up for the most part is pretty simple and easy.
One of the best things I like about these arms is the cable management. I had several arms before for my setup at home and work, and the cable covers are usually pretty flimsy and just slide and lock in. I have a lot DP and HDMI cables due to my dual workstation, so these cable covers often end up popping out since its so full. These cable covers are different since they are screwed down tight with a bolt. All my cables fit pretty snug, but there is no bulging and I don't have to worry about the covers popping off ever again. I'd recommend keeping it at a maximum of 4 thicker cables though. However, fair warning that attaching the covers can be a pain so if you have to detach cables often, the screwed in covers can be a problem. If you have a set up like mine that won't really change often, it works well. If you can, I would suggest having 2 people set up the cable management. One to hold down the cover in place and the other to screw it in. I did it myself just fine though.
The range of motion is great for my needs, but please note that I tried stacking my monitors and it didn't quite work. I would say it's 1 to 2 inches shy of properly stacking them.
Overall, a great looking set of dual monitor arms. The extra ports on the base are a cool feature that do work, but I haven't had much use of it yet. Love that they had a white option to match my set up too. These are a little pricey, but they're really worth it!

Review of AVLT Dual 13"-35" Monitor Arm Desk Mount
I do not usually rate items, except for products that are exceptional or are provided by a vendor that is above all others.
I looked at this item several times, because the price was $100 less than my five year old dual arm could not raise the 38” monitor more that 8” from the desk surface and barely keep my wiring hidden.
Finally, the website for AVLT convinced me to place the order for the AVLT-DM41-1, Dual 13"-35" Monitor Arm Desk Mount. I was not disappointed.
The quality and finish of the aluminum mount is space age quality, the manual acceptable (ilea type); most important the I can raise my 38” monitor to a perfect ergonomic height.
My monitors are a Dell 38” U3818DW, (larger than 13” to 35” range) and a Dell 24” U2412M, U. for each I use the factory power cable, DP to DP display port 6 foot cables and high speed USB 3 cables for each monitor.
The assembly went without a hitch, no problem hiding the heavy cables that I use, my only problem was that my was not a C-clamp, attaching the hex bolts to the base from the underside of my desk was difficult; t would had been easier had they used a stud bolts to clamp the unit down.
The arm springs had no problem supporting my 38” monito, the unit is so sturdy I expect to receive years of service.
I strongly recommend this item because of value, quality and design. You will be hard pressed to find an equal or better product regardless of the price.

Great product
Color: White-Mount
Amazing product. It’s perfect. Tried a few other dual monitor arms and they sucked and didn’t hold up the monitors. This one is amazing and aesthetically pleasing. Well worth the money. All parts included. Large range of motion, you just have to loosen the screws to make it easier to move or tighten to keep everything still. Perfect size and provides all my amount of desk space back.
