Good for the price. Some limitations
Size: 0.7 ft, Style: USB-C
These work well. Make sure you don't put too much current draw on it. In my case I'm using it just for a keyboard and mouse. When I added a 2.5 inch HDD it stopped working. Re-read the instructions and sure enough power draw is the problem. BUT - it still works well for my application as long as I don't expect too much power delivery.

Very good product
Size: 2 ft, Style: USB-C
This is the second one I order. This time, the blue LED light is so weak, that is difficult to tell it is connected. But it works, and works very well! I would buy another, if I needed it.

Great for adding USB ports to any USB-C device.
Size: 0.7 ft, Style: USB-C
I needed this to allow for more USB connections on my laptop. It is totally compatible with any USB-C device. I like the small blue LED on it that shows it is powered on. It's very small and lightweight and inconspicuous in design. Love the value for the price.
