Thank you for viewing. I have been using this mainly for live performances until recently, but I am selling it due to a change in equipment. This is a set including a receiver, a transmitter, a transmitter cable, and an adapter. As you can see, the battery cover of the transmitter is damaged. I have been using it by taping it with clear packing tape as shown in the image, so I am selling it as junk. The transmitter requires two AA batteries. There is considerable wear and tear, so I would like to sell it as a junk item with no claims and no returns. I hope you understand. Thank you.
