Logitech MX MASTER2S Logitech Logitech Wireless Mobile Mouse Black m6 I used this mouse for about a year, but I'm selling it because I upgraded to a newer model. The mouse wheel and thumb wheel have undergone hydrolysis, so they have been replaced with metal wheels, making them durable for long-term use. The mouse feet have been replaced with new ones. The left and right click switches have been changed to silent buttons (genuine kailh). It can be connected via Bluetooth or a dedicated USB receiver. Only the mouse itself is for sale. If you want the USB receiver, it's available for an additional 600 yen, so please let me know. Series: Master Connection method: Bluetooth + Unifying USB receiver 【High-precision laser sensor】 The MX Master 2S is equipped with a high-precision laser sensor, allowing for smooth operation on various surfaces. 【Multi-function buttons】 It has 3 programmable buttons that can be customized to improve work efficiency. 【Wireless connection】 You can easily connect via Bluetooth or a USB receiver, keeping your desk tidy. - Brand: Logitech - Model Name: MX Master 2S - Color: Gray - Number of buttons: 3 - Connection method: Wireless - Sensor type: Laser - Supported OS: Windows, macOS
