With the Logitech M720 Triathlon Wireless Mouse, you can control up to 3 devices with one mouse. One press on a button allows you to switch between different devices, which is useful if you work on multiple devices at the same time. You can connect the mouse to Bluetooth devices, like your laptop or Windows tablet. If you don't have Bluetooth on your computer, you can connect your mouse via the unifying USB receiver. You'll almost forget that the mouse is wireless, because it can last up to 24 months on a single battery. With the thumb buttons, you can quickly navigate through your files and programs. It's also possible to assign functions to the buttons yourself via Logitech Options software.
