The Lenovo N700 is the most diverse Bluetooth mouse in our review, if you don't count compatibility with operating systems. It can communicate with your computer wirelessly via Bluetooth or a 2.4GHz Advanced Wireless nano-dongle, which requires a USB port. It's also a laser pointer, making it the best Bluetooth mouse for presentations and lectures.
The N700 was among the most accurate Bluetooth mice we tested on laminate and wood surfaces, but it scored an average 85 percent on denim and carpet. It scored a low 70 percent on marble and completely failed on glass. Overall, you'll find it works well enough on most surfaces that aren't glossy.
It has two modes – Bluetooth and 2.4GHz Advanced Wireless. Since there's no difference in the performance of the modes, there's no reason to use the 2.4GHz Advanced Wireless mode, which requires you to plug a tiny nano-dongle device into a USB port. The only purpose for that mode would be if you had a computer that didn't have Bluetooth capabilities, which are almost ubiquitous in computers these days. When the mouse is in the flat position, it also works as a laser pointer, which is superfluous unless you give presentations or lectures in which you need to point at information on a projected screen. The laser pointer doesn't communicate any commands to your computer. It's simply a pointing device.
The bottom of the mouse revolves, turning it from a flat device the size of a smartphone to the shape of a mouse. The rigidness of the shape doesn't lend itself to a comfortable palm grip, but it works well with the claw and fingertip grips. When it's flat, the shape makes it one of the most portable mice in our review.
The biggest downside, which is significant, is the lack of backward compatibility with Windows. The mouse only works on a Windows 8 operating system. All the gestures are optimized for the tile app interface, allowing you to easily swipe, scroll and zoom with simple finger movements, but even the cursor won't move when connected to Windows 7 or lower. Since Windows 7 is more widely used than Windows 8, this severely limits its effectiveness.
