Having used the U-Com2 units very successfully for years, when my wife needed comms, the Interphone U-Com3 was a trusted first choice. The quality of the components, ease of fitting, user experience of the App, and reliability of connectivity are just the same as the -2 variant, but now with the battery included in the control unit. I’ve successfully twined with higher price SENA units, and my -2 units. My previous Interphone gear has proven 100% reliable in year-round, daily commuter use, with no speaker, mic, or wiring connection issues, so I have faith that the -3 will provide years of reliability.
