[3in1 Pack] USB 3.1 Type-C Extension Coupler/Adapter Set:1pc USB C Male to Male, and 1pc C Female to Female,1pc C Male to Female Compatible with Galaxy S8, MacBook, Nintendo Switch, XZ, G5, Pixel,

I bought a USB Type C KVM Switch, however, its "main output" is a male USB-C plug. But my USB-C/HDMI hub's main "input" to the monitor (with keyboards and mouse plugged in), is a male USB-C plug as well. This female/female USB-C adapter allowed it to work perfectly. Now I can switch between two Macs and use the same set of monitor, keyboard and mouse.

The male to male coupler makes it so much easier to transfer information quickly between two android phones

Product is great except it will only work in one direction unlike all usb-c cords.

. . . well it didn't work and I started to freak. Then one night I accidentally flipped the cable over and plugged it in and it worked! So Yeah it's not flippable on some cables. (only the Apple cable works either way) So good buy for what it is.

I took a chance on this product knowing it might not work. I used it to connect a male flash drive reader to a male C connected to my computer and it worked ! I was able to read both SD and CF card.
