Logitech MX MASTER2S Logitech Logitech Wireless Mobile Mouse Black m5 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. 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. The free-scrolling mode isn't very smooth, so I've priced it a little lower. Series: Master Connectivity: 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 three 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 - Connectivity: Wireless - Sensor Type: Laser - Supported OS: Windows, macOS
