I have the MX-3000 and use it with the MRF-250, which most say has issues. My remote and RF base work flawless. I never have a problem with my devices receiving the proper signals.

My one and only issue I have is the volume hard buttons. Half the time when I press and hold the volume button, it does not repeat constantly. The volume only goes up or down one notch. I sometimes have to press and hold the buttons several times before I get it to move properly. I suppose this may be the way I coded it and not due to the actual relaying of the signals between the remote, the rf base and all the devices.
