Thank you for viewing. This is a PlayStation 5 DualSense controller. The "Square, Circle" buttons were slow to respond, so I disassembled and cleaned it, but the R2 and L2 buttons stopped responding. (R2 responds with a delay, L2 does not respond at all.) The cause is unknown, but it seems to be an electrical failure rather than a mechanical one. (I used contact cleaner, so the parts may not have been compatible.) The exterior has no noticeable scratches as shown in the photos, so if you replace the L2 and R2 parts, it will likely work fine. (However, I cannot guarantee operation.) If you are interested in it as a repair part, please consider it. ＜Additional Information＞ Controller included with CFI-1200A (purchased December 2022) ＜Notes＞ ・Please refrain from price negotiations. ・I have disassembled and maintained it once.
