Excerpt: The Kensington SlimBlade Bluetooth Presenter Mouse is a blend of navigational mouse and presentation tool. The Bluetooth mouse can be used for every function that other devices have. You’ll have four-way scrolling and a great optical resolution. However, the Kensington product also has an option to switch to presentation mode to use the left and right buttons to click through the presentation pages.
Pros: This mouse has a built-in function to navigate through PowerPoint presentations.
Cons: The mouse is not very comfortable, especially for anyone with large hands.
