Thank you for viewing. [Brand New] [Specifications: 6 buttons with side buttons] Simply plug the receiver into a USB port and it's ready to use. It doesn't have any special features, but it has the minimum necessary functions, so I think this is sufficient for everyday use. Unlike rechargeable mice, this uses two commercially available AAA batteries, so you can use it for a long time. Description • Wireless Connection: Enjoy freedom of movement with a 2.4Ghz wireless connection, eliminating the need for cords and cables. • Ergonomic Design: The mouse is designed to fit comfortably in your hand, reducing strain and fatigue during extended use. • Universal Compatibility: This mouse is compatible with a variety of devices, including laptops, desktops, and game consoles. Thank you. Power supply... Battery powered Connection type... Wireless (Bluetooth)
