Very reasonably priced, the unit came on time, I used it at my home base, a Class C Airport. Worked like a champ. All connections appear solid. My headset plugged in just fine.

Works as advertised. Note, if you are using a portable intercom, plug the intercom mic jack into the panel, and ptt into the intercom jack.
