I purchased this about three years ago, but I only used it for APEX, so it's in relatively good condition. I had a dust filter on it until last year, but I removed it for the past year. I've done some light wiping and cleaning with cotton swabs as far as I can see, but it's not perfect, so I hope you understand. I haven't disassembled it. I'm also considering selling it to GEO. Notes: 1. I replaced the controller charging cable with an Anker product. 2. I replaced the HDMI cable with an ELECOM one, as recommended by a friend who knows more about these things. 3. There is only one black controller. Everything works without any problems. I will carefully wrap the product box in bubble wrap for shipping. Thank you.
