The name sums it up: They don't work. When I plug them into my computer, they connect for a few seconds, then disconnect, then reconnect and don't stay connected. I bought these for my old laptop with only a USB port and had the problem described above. I thought it might be a USB-C to laptop adapter so I tried the adapter on my 2019 laptop and also the USB-C port on my 2019 laptop. Same problem. I also tried using USB C on my 2021 MacBook and encountered the same issue, so I believe they are buggy. You may not have a defect, but I had it so you can risk it, but I just wanted to share my experience.
