Triple Portable Monitor, Ips FHD 1200P Laptop Monitor Extender, Full-Function Type C/Hdmi Ports, Foldable Dual Screen Extender for 13.3"-17.3" Compatible with Windows, Mac

Just set up on Macbook Pro M4 (2024) under Mac OS 15.3 (Sequioia) with supplied USB-C to C cable, following supplied setup instruction cards and "USBDisplay" app. Working fine (so far) as extended displays, using default resolution. (Note: Pointer size needs to be adjusted to large so that it doesn't disappear when moving between displays.)

Totally unusable. Because the kickstand was too springy to close, I could not tilt the screen. Additionally, since it does not attach to the computer, it could only be used at approximately a 45° angle, making it impossible to see. Picture quality and one cable functionality work as advertised, but I was not willing to jerry-rig the screens every time I wanted to use them. Poor design.
