Product: Fnatic Gear Fnatic x LAMZU THORN 4K Special Edition, 4000Hz Polling Rate Compatible This is a gaming mouse compatible with 4000Hz. As shown in the third photo, the accessories include: Dongle (4kHz compatible), included mouse feet, charging cable, instruction manual, and the included Fnatic sticker. I purchased it around the end of last year and used it for about 2-3 months after that. I used it very carefully, so I think it's in good condition. The reason I decided to sell it is because I felt that ergonomic mice didn't suit me, having used ergonomic mice for about six months, including the mouse I used before this one (pulsar xlite V2). I kept it, thinking I might want to use it again after a while, but I didn't, so I decided it was a waste and listed it for sale.
