WALI Triple Monitor Mount, 3 Monitor Stand Desk Mount with Premium Gas Spring Arm for Screens up to 27 inch, VESA 75x75 or 100x100 mm (GSDM003W-U), White

Quality product. Well made, supports three monitors with ease.

Setup was very easy, and counter to my experience of desk mounts a few years ago, doesn't require octopus-like abilities to hold monitors in place while attaching VESA brackets. This desk mount has brackets which slot into place and are self-supporting while you fasten the screws.I chose to install using the through-desk option, rather than the conventional C-clamp, which involved drilling a hole through the desk. It feels sturdy, though it doesn't benefit from the cable management clip that works with the clamp.I'm not sure what I was expecting from the USB ports, but they're just port extensions rather than being a hub - which means you need two spare ports to plug them into. I'm also pretty sure that they're not USB 3.0 as claimed by the product video, despite being the telltale blue, but I use them for low-speed devices anyway.The arms are pretty solid, and don't bounce or wobble when raising/lowering my sit/stand desk. The middle monitor is 27" landscape and the two outer monitors are 24" portrait. After initially setting them up a couple of months ago, I have not had to readjust the mounts for orientation or tilt, despite raising and lowering the desk probably 3-4 times a day.Cable management is simple and effective, although I did have to convince the cable channels to accept power and HDMI cables together - power and DisplayPort cables together were fine. The arms could have done with some loops for additional cables or cable ties for tidying up cables from other devices (e.g. webcam, monitor light).Overall I'm happy, and would probably buy it again if I didn't see anything significantly better at around the same price point.
