This is the smallest WiFi 6 BlueTooth 5.3 USB dongle in the world (to my knowledge). It's quite efficient, and is a really simple security, speed, and latency upgrade. Simply find a USB port, and plug this device in. It almost doesn't stick out, and doesn't get too warm while operating. This is intended for use with PC laptops, and may not work with MacBooks. I opened the package to check the contents, but it has not been used for any appreciable period of time.
