This is the best $20 upgrade I've ever made. Just plug in the USB dongle and it auto installs. I keep it in a zipper bag when using it, about the only clean item near my table.

(Power switch is still easy to access when its in the bag)
Found it on Amazon. Been using it for a few months now. (Also works great on my Smart TV) Scroll to bottom for video.
Here is a short video demo.
