I'm selling a GPRO X SUPERLIGHT that I purchased three years ago. I bought it with the intention of gaming, but I didn't have the talent, so I rarely used it for games. The included accessories are: LIGHTSPEED wireless receiver, USB A-C charging/data cable, receiver extension adapter. The mouse wheel is experiencing chattering. It doesn't happen frequently, but it reverses the operation about once every 10 clicks. Regarding battery degradation, Since there are no numerical values, it's based on my experience, but I don't think it's degraded much. It lasts for a month on a single charge.
