This is the one mouse you can rely on to work with whichever platform you work on. Connect to any Bluetooth-enabled PC or Mac computer or Windows 8 tablet. Whether you're a righty or a lefty, whether you use a fingertip or palm grip, its slim, ambidextrous design is always a perfect fit. It offers up to 12 months of battery life, so you can work for up to a full year between battery changes. Battery life may vary based on user and computing conditions.
