  1. Laura M

    Works great. End users love not being strapped to a console and being able to move around. This device maintains connection for a good distance.

  2. STEPHANIE R (verified owner)

    Great product. Very helpful, easy to use.

  3. Susie

    When I hooked up this device to the workstation, something opened up the radio channel and there was nothing but dead air. Once I unplugged the unit, the open channel stopped. Waiting for a slow time to plug the unit in and do some trouble shooting.

  4. Team Procurement VooDoo

    This product was as advertised. It met our requirements and was good quality. Pricing was also reasonable based on competitors. will use this vendor again.

  5. Reynolds
