I get this rf to usb keyboard in the hope that it would eliminate some of the cord tangle at the operating bench in my ham shack . it work just great . I wish the receiver end that stick in the usb port be a little bigger tho . I have little doubt that I will eventually lose it in the chaos on my desk . the keyboard work the first time I try it . there be no direction with the unit I receive , but it be not rocket science to get it up and run . test it on computer with xp pro , Vista and Windows 7 o\/ss and in a high rf environment . no problem note . definitely a good thing for ham or other folk who work at they com ; puter station .
