Review: works for switch 2 dock - bought to use and connect my switch 2 dock to my switch 2 so i don't have to have the switch 2 in the dock. i keep my dock behind my tv and my switch in front, this allows me to extend the dock so i can do this. it was for sure hard to plug into the dock, but that is the dock design. once plugged in this cord stays and works perfectly.
Review: connects to a PC laptop and a Mac Mini M4. - Why did you pick this product vs others?: these cables work perfectly. i used one on my Mac Mini M4 and a second one on my Dell Lattitude Laptop. then i switch between them with the usb-c cable from my Pluggable Dock that has all the connections to my (2) monitors, printer, keyboard, and mouse. everything runs fine. i was worried about the video, but that works perfectly. i'm just running both monitors at HD (1920x1080).

### ⭐⭐⭐⭐⭐ connects to a PC laptop and a Mac Mini M4.

### ⭐⭐⭐⭐⭐ Workaround for Red VRaptor proprietary USBC Cable
*by S***Y on November 16, 2025*

I used this plus a USB extender as a workaround for Red's dumb proprietary $100 USB cable for the VRaptor's monitor. Don't let Red fool you -the only thing that's different about their property cable is the width of the plug chassis and the fact that it lacks an E Marker chip. (I guess this cable must lack an E Marker.) Just use the tiny short USBC Cable that Red supplies with the VRaptor, plug it into this cable, and plug this cable into a USB extender that's thin enough to insert into the plug on the camera body and you're up and running.
