I've only used the switch for about a week but it's great for situations where you need an extra port but only have one. I troubleshoot client networks and most of the time they don't have a free port or power source nearby so you don't need an external power source if you have a USB port. Please note that the USB adapter is a special proprietary connector. So if you lose him, you're out of luck. There is also no external power supply as with wall mounting.
