Logitech’s M187 Wireless Ultra Portable Mouse is a small mouse with built-in 2.4 GHz wireless connectivity and a tiny receiver. It may be conveniently stored in your backpack or even your pocket, allowing you to take it with you on the go. Furthermore, its receiver is small enough that you can leave it connected to your system without fear of it being lost or broken. A single AAA battery powers the M187 mouse, which can last up to six months depending on usage.
