Solid Mount for a Large Monitor
Size: 17"-49", Style: Single Arm
Picked this up to mount a single 37" monitor to my adjustable desk and it’s been working great. The arm feels sturdy and holds the weight of the monitor without sagging or drifting over time.
Installation was pretty straightforward and it gave me a lot more desk space compared to using the factory stand. It also moves smoothly when adjusting the monitor position or changing desk height.
If you’re running a larger display on a standing desk setup, this is a solid option that feels much more substantial than some of the cheaper monitor arms out there.

Solid Budget Monitor Arm With a Few Trade‑Offs
Size: 13"-34", Style: Single Arm
The WALI Single Monitor Mount performs about the same as my VIVO single monitor arm, which was a pleasant surprise given the lower price point. Setup was straightforward, and the gas spring adjustment works well once dialed in. It holds my monitor securely and offers the full range of motion I expected—tilt, swivel, rotation, and height adjustments all function smoothly.
That said, the materials and overall build quality do feel a bit cheaper compared to higher‑end arms. It’s not flimsy, but you can tell where costs were saved. If you’re willing to spend roughly 60–70% more, you can definitely get a noticeably sturdier and more refined arm. Still, for a budget option, this one delivers exactly what it promises.
Pros
- Works just as well as the VIVO arm in terms of functionality
- Easy to install with both clamp and grommet options
- Gas spring provides good adjustability once set
- Excellent value for an entry‑level monitor arm
Cons
- Materials feel cheaper than premium alternatives
- Build quality isn’t as high as more expensive arms
Overall
As an introductory monitor arm, this is an excellent choice. It does everything the VIVO arm can, just with slightly lower‑end materials. If you’re on a budget or setting up a simple workstation, it’s a great fit. If you want something more robust for long‑term heavy use, spending a bit more will get you a significantly more refined Monitor arm.

Sturdy and easy to assemble
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
Really impressed with this monitor mount. The build quality feels solid and sturdy, especially for the price. It holds the monitor securely with no sagging or wobble, and the adjustability makes it super easy to get the perfect position. It’s been absolutely perfect for my sim racing setup being able to move the screen exactly where I want it made a huge difference in comfort and immersion. Definitely feels like a premium product without the premium price tag.

Reliable, affordable, and user-friendly
Size: 13"-34", Style: Single Arm, Size: 13"-34", Style: Single Arm
The installation process was straightforward and didn’t take much time at all—even if you’re not particularly handy, it’s easy to figure out.
What really stands out is how flexible the arm is. It adjusts smoothly in multiple directions, making it simple to position my monitor exactly where I want it. Whether I’m working, watching something, or multitasking, the range of motion makes a noticeable difference in comfort and productivity.
It’s also very sturdy once set up. My monitor feels secure, and I haven’t experienced any sagging or instability. As a second screen mount, it integrates perfectly with my desk setup and helps keep everything organized and clutter-free.

Solid Build, Easy Setup
Size: 17"-49", Style: Single Arm
I picked up two of these mounts — one for my 34" curved LG ultrawide and one for my 30" MSI ultrawide — and both have performed exactly as advertised.
Build Quality & Value
For the price, this thing is built surprisingly well. It feels solid, looks clean on the desk, and doesn't have that cheap, flimsy feel you'd expect at this price point. Genuinely impressed.
Assembly & Installation
Setup was straightforward. Everything you need comes in the box. The only tool you'll need to grab yourself is a ½" wrench — have that ready before you start and you'll be done in minutes.
Mounting Options
Two ways to mount it: clamp-on or through-hole (use an existing grommet hole or drill a new one). Both options feel secure once locked down.
Sturdiness & Adjustability
Once mounted, the arm holds firm. No drooping, no wobble. Repositioning the monitor is smooth and easy — tilt, swivel, height adjustments all work well even with the larger ultrawide panels.
One Thing to Watch
The tiny limiting screws ship loosely packed inside the arms. They're small and easy to lose if you're not paying attention when you open the box. Dump the contents carefully over a flat surface before digging in.
Bottom Line
If you're on the fence about a monitor mount, stop overthinking it and grab this one. It handles large ultrawides without breaking a sweat, installs fast, and won't break the bank. Highly recommended.
