The LOGITECH M240 Silent Bluetooth mouse is a high-quality and reliable device with extremely quiet operation. An ideal choice for both work and play. A sculpted, contoured shape, reliable Bluetooth® connectivity and 18-month battery life let you focus on what you do best. It fits easily in the bag next to your laptop, so you can take it with you wherever you need it.

It is designed to be equally comfortable for left- and right-handed users. Thanks to the contoured design following the natural line of the hands, it enables fatigue-free, long-term use. The special, concave buttons guide the fingers to the ideal position, while the palm rest provides comfort all day long.

Thanks to the controlled line-by-line scrolling function, you can navigate more easily, without annoying and missed clicks. The optical sensor provides smooth and accurate cursor control on almost any surface. SilentTouch technology reduces clicking sounds by 90%, but maintains the familiar clicking sensation.

Durable and reliable, it works for up to 18 months without changing the battery, thanks to the power button and the energy-saving mode that automatically enters the sleep state.

Connects in seconds with a reliable Bluetooth® connection - no adapter or port required. Works with Windows, macOS, ChromeOS, Linux and Android.
