hkt-7000 6 pieces I have confirmed that all 6 units power on and the directional pad, A, B, MODE, and other buttons function. Also, all data has been erased. Since there is no main unit or controller, I cannot confirm anything further. There are scratches and dirt. Two units are missing the tip cover. There is discoloration on the back. Please consider purchasing only if you understand the above. They will be shipped together in a Nekopos box without individual packaging. Batteries are not included.
