Looking beyond the battery charger, the actual insides of the mice work much better than that of other wireless optical mice. The MX700 boasts two major improvements relating to how the mouse works: Fast RF cordless technology, and the new MX optical engine. The Fast RF technology greatly improves the response time of the mouse. Previous cordless mice transmitted data to the PC at approximately the speed of a PS/2 port (about 40 Hz). With the Fast RF cordless technology, this mouse can transfer data at approximately the speed of a USB port (about 125 Hz). This difference is incredible: there is basically no lag between when you move the mouse and when the computer updates the mouse arrow on the screen. Lag has made other wireless mice difficult to use for games, which is why many gamers would not use them. This new technology means there is very little difference between a corded USB optical mouse and this wireless one. In addition, like some other wireless mice, the mouse operates at a frequency of 27 Hz, which does not conflict with the 900 MHz band. It has two channels, so in case another device is interfering with the mouse, you can change the channel with the connect button on the charger and the mouse itself. The new MX engine improves the optical sensor of the mouse. It has a scan rate of 4.7 megapixels per second. This is about 60% more than previous mice, and means that more data is transmitted in the same amount of time, which makes movement smoother on the computer. The resolution of the optical sensor is 800 DPI, twice that of most other optical mice. This means that you can move the mouse approximately 40 inches per second, and the mouse will not “jump” on the computer screen. No matter how fast I moved the mouse on a flat surface, it would not jump. This is much better than even corded optical mice, which jumped frequently at high speeds. The MX engine takes advantage of the Fast RF technology, since with the technology it can transmit the data at a much faster rate. Next Page: The technology
