Overview

The HP 240 Bluetooth Mouse in Empire Red is a compact wireless mouse built for everyday computing. It connects via Bluetooth 5.1, which means there is no USB receiver to lose or occupy a port — a genuine advantage for laptop users who are already short on USB connections. The 1600 DPI optical sensor provides smooth, accurate tracking on most surfaces, delivering responsive cursor movement for tasks like document editing, spreadsheet work, and web browsing. While the DPI is fixed and not adjustable, 1600 DPI is a well-chosen default that balances precision and speed for general productivity.

The mouse has a symmetrical, slim profile that fits comfortably in either hand, making it one of the more inclusive designs in HP's peripheral lineup. It features three buttons — left, right, and a clickable scroll wheel — covering the essentials without adding complexity. Battery life is rated at up to 15 months on a single AA battery, which is included in the box, so you can expect months of use before needing a replacement. The Empire Red finish gives it a visual identity that pairs well with HP's similarly colored laptops, or simply adds a splash of color to any desk setup.
