I hadn't thought that a video remote controller had an expiring term. My former controller had lost its power gradually so I couldn't change channels and operate options. BTW, I once ordered another secondhand remote controller with another agent, but it was under very bad conditions. At this time, the agent wrote the controller was secondhand but not used. I bet and won. This remote controller was perfectly new, and I could operate it comfortably. Thank you very much. I appreciate your deal.
