What to know before buying

The manufacturer says the side buttons switch between applications in Mac mode. It also states that Ubuntu and Mac do not support the middle-button scroll-wheel function.
Feedback is mixed on size, responsiveness, reliability and button operation. Some customers say the mouse is too large for small hands, so check its fit preference before choosing it for extended use.

Listing details to confirm

Listing details are inconsistent about the battery: the explicit component list names one AA battery, while product details say batteries are not included and the feature note says the battery is not included. The colour is listed as both Black/White and Black in the title. The listing also describes Bluetooth and 2.4G connections but does not clearly establish whether the mouse pairs with multiple devices simultaneously. Confirm the selected listing and connection arrangement before purchase.
