Look at another mouse offered by A4tech called the X-750F Laser Gaming Mouse. This particular mouse can adjust it's DPI from 600-2500 DPI 'on the fly' while gaming and features a unique Triple fire button.
The X-750F Laser Gaming Mouse comes in black and chrome. This sleek looking mouse with it's highly reflective surface is geared more towards a right handed individual. This becomes evident in the layout of the buttons.
The mouse also comes with a USB to Serial port adapter and Driver/Application CD.
The first thing you notice about the X-750F that makes it standout from other mice is it's extra orange button. This extra button called the Triple Fire button allows as the name implies, the need for only one button press to achieve three left clicks.
On the left side of the mouse are two programable buttons and a textured thumb grip. Both buttons can be programmed with the included Application CD to perform various windows and browser tasks, such as maximize, minimize, back, forward, etc.
Just above the scroll wheel is a single button that allows instant adjustments of six DPI sensitivity levels: 600, 800, 1200, 1600, 2000 and 2500dpi without the need to install a driver.
With six sensitivity levels it would be hard to figure out what level you have set the mouse without some kind of indicator. Thankfully A4tech came up with a solution in the form of a light-up scroll wheel that changes colors to indicate the level of DPI sensitivity.
From the above picture we can see that 600dpi is white, 800dpi is green, 1200dpi is yellow and the 1600dpi is red. As for the last two setting 2000dpi and 2500dpi, they flash between red and yellow, and green and yellow respectively.
