I installed the KRT2 adapter today. The adapter is very small, the housing seems very sturdy, and the mounting clips on the connector hold well. The entire installation only takes a few minutes and it works flawlessly. In SkyDemon, all you have to do is select the radio under "Third-Party Devices," save it, and you're ready to use the function.
