DualSense Wireless Controller (Official) - Model: DualSense Wireless Controller - Color: White/Black - Brand: Sony - Battery Type: Lithium-ion Thank you for viewing. I purchased this a year ago and used it for about six months, but I haven't used it since the right stick started malfunctioning. It seems like it could be repaired by opening the cover and cleaning it, but it's impossible for me because of my nails, so I'm selling it as a junk item. Thank you for your consideration.
