3 MultiVoice MVR900 Full Multi-Plex Wireless Communication with headsets

Description

You are buying 3 units with rubber covers and 3 headsets ( 2 single headsets and 1 double headset with missing ear pad). All in very good condition. The main units are cosmetically 8 out of 10, the headsets are cosmetically 6 out of 10. I don't know how old they are. We've tested them according to the manufacturer video and I could hear myself on the headset, talking to the mic. I don't know how to link all 3 together so somebody please chime in to educate me. I have only one mini USB cord that came with the set, no charger. The net says you charge them thru the miniUSB port but I don't know if they need a brand specific charger. We ship to the continental USA only. NO PO BOX PLEASE. The triple set is new 3750 dollars on line from the manufacturer. Please make sure this is what you need cause we don't offer returns. I answer questions and gladly provide you with some extra pictures if needed or you can guide me thru a specific test of the units.
