Incredibly sturdy and well-made
It feels really sturdy and secure, and once adjusted properly, it moves smoothly without feeling loose or drooping on its own. You can easily reposition your monitor and it will stay in place very well. It's expensive, but very much worth the money, as it definitely feels like it could easily hold a very heavy monitor without you worrying about it falling off. I have total confidence in this arm, unlike some others I have used. There was, unfortunately, a missing piece in the unit I bought, but there was a card included in the box with a customer support email that they specifically recommend contacting if you have any missing pieces. I sent them an email and they very quickly arranged to send me the missing part with tracked shipping at no charge. Excellent customer service for an excellent product.

Supports samsung g9 oled (and g8 stacked)
More expensive than other monitor arms out there but it is well build and solid i have both the main arm and the second arm also, the are supporting a samsung g9 oled on the main arm and a samsung g8 oled on the second arm with bit above "stacked" both monitors are solid and have good move ability when needed once the tension screw is adjust correctly. I would recommend. Also indid see another 1 start review because the arm snapped the corner of the deck apart..... this sold it to me as it shows the arm is sold.......just don't clap it to a weak desk!!!!!!

It works, it's solid, and creates a very clean look.
Did exactly what I needed it for. Held my Odyssey G9 along side my 27 inch vertical monitor. Whilst being clamped to the desk. Value is in the eye of the beholder but any other monitor arm on the market thst advertises the ability to hold the Samsung 32:9 widescreens seem excessive in price. But you wouldn't want to mount it and risk damage to the monitor. Easy to put together. Stable and solid. Cable mount / run channels could do with being a little deeper and no so close to the edge of the arm section. As it makes it tight to get them back on when you have thick cables. Also nice touch to get a free cup coaster for your desk (wish it was black ;p). But Thank you.

It’s a pretty good product
I didn’t thought it would arrived in just a few days. Ordered it for a good friend of mine from UK to Germany. I asked a few questions before and the seller is so kind and answered asap. The whole set is so so good looking. Thanks for your product. It’s worth the price :)

Amazing holds up my 2 super ultrawide monitors no problem.
Got this as i ordered 2 super ultrawide monitors, and holds them up no problem, consturction was easy with good instructions, a slot for you to feed your display port of HDMI cables to keep it clean and stays exactly where you want it.

Solid mount, Easy to install, VESA mount a bit large for my Samsung monitors.
Great product. I purchased one for my two Samsung Odysseys ultra-wide monitors, at first I thought the VESA plate is causing the monitors to tilt downward, (The VESA plates are too large at the top as the monitors have a rounded back area and the VESA Plates should fit inside the circular recess, I guess) but I noticed I was still learning how to adjust movements. Overall great quality and functionality, my space looks clean and saves desk space.

Strong and well designed
The ULTRARM Heavy Duty Extension Arm is a robust and well-engineered accessory designed to complement the MA20P-S Single Monitor Arm. It’s perfect for anyone looking to stack dual 49-inch monitors vertically while maintaining adjustability and stability. Pros: Heavy-Duty Build: The extension arm is built to support large monitors securely, with no noticeable wobbling or sagging, even with heavier setups. Height Adjustability: The height adjustment feature works smoothly, allowing you to customize the position for an ergonomic viewing experience. Compatibility: Designed specifically for the MA20P-S arm, it integrates seamlessly and supports VESA 100x100 mounting standards. Clean Design: The black finish looks sleek and professional, fitting well in any office or gaming setup. Space-Saving Solution: Vertical stacking frees up desk space while providing an immersive multi-monitor experience. Cons: Accessory Only: This extension arm cannot be used on its own and requires the MA20P-S Single Monitor Arm, which might limit its appeal to first-time buyers. Assembly: Installation can be a bit challenging, especially for larger monitors, and might require a second pair of hands. Overall Verdict The ULTRARM Heavy Duty Extension Arm is an excellent accessory for those who need a vertical dual-monitor setup. Its sturdy design and adjustability make it a great investment for professionals or gamers seeking a reliable and space-efficient mounting solution. Rating: 4.5/5 Highly recommended if you already own the MA20P-S monitor arm and want to elevate your workspace with a durable and stylish extension arm.

Ottimo, migliorerei la gestione dei cavi
Ho già scritto una recensione del braccio con supporto, non posso che confermare anche qui il lavoro di fino del progetto. Unica pecca magari le plastiche copri cavo se spinte un po’ troppo saltano ma in cavi hdmi e usbc moderni sono molto ingombranti e rigidi

しっかりした作り、大型モニターをしっかり保持してくれます。
延長用なので、基本セットが必要です。基本セットを購入し、気に入ったので追加で購入しました。 上下にウルトラワイドモニターをセットしていますが大満足です。
