Computer mice have come a long way since their induction. Back then, there was only white-beige colored, 2 button, ball mouse. Today, we have high sensitivity optical sensors, laser sensors, scroll wheel with tilt feature, 8-10 programmable buttons, gold plated connector, adjustable weights, and even a phone integrated into a mouse. Mouse is no more an ordinary piece of technology. It is one of the most rapidly evolving piece of computer hardware, without which computing is no more the same. Razer has been at the forefront of evolution. Today, we have yet another evolved mouse from Razer which is specially targeted towards the RTS/RPG crowd. With the growing popularity of MMORPG games, having a mouse specially designed for it makes sense. But, how can a mouse be designed for RPG games, where you don't need the accuracy and precision meant for FPS games? Read on.

RTS/RPG games involve lots of quick decision making and consequently button pressing. An expert RTS gamer can micro manage every unit individually with ease. The number of buttons he presses in a minute is called as APM or Actions Per Minute. Razer Krait claims to support 1200 APM. Let's do some math. 1200 APM is equal to 1200 Actions divided by 60 seconds; that is around 20 Actions per second. Now, the deal over here is that no matter how fast you click the buttons, one just cannot click buttons 20 times. Even if you press left, right and scroll at full speed, achieving 20 actions is impossible; at least for us. But the idea over here is to convey the message that this mouse is the ultimate mouse for a RTS/RPG gamer. Frankly speaking, none of this APM feature really impressed me. My old Logitech MX518 is able to execute all the commands I give without any problems and not once have I felt like I am missing anything. The Razer Krait's 1200 APM is nothing more than a marketing gimmick. However, the mouse has some hidden potential.

It incorporates the same sensor used in the Logitech MX 518, Genius Ergo 520 and Razer Diamondback; the ADNS 3080 manufactured by Agilent. It is a 5.8 Megapixels sensor capable of tracking 1600 dpi with a capture rate of 6500 frames per second, at a max acceleration rate of 15g. The only difference being that this mouse incorporates an infrared beam instead of the usual red thus giving an impression that it's a laser sensor. However this optical sensor is perfect for users who favor extreme high sensitivity. It supports adjusting sensitivity on the fly (400, 800 and 1600 dpi) but with the help of the bundled software, unlike the MX518 or G5 that let you change the sensitivity using buttons without the need of any drivers or software.

It interacts with the PC through the USB bus using a 16-bit data path per axis. For better connectivity, it has a gold plated USB connector. In terms of physical dimensions, it is identical to Razer Diamondback, with the exception of the side buttons. The lightweight and symmetrically designed body makes it a mouse that can be controlled more by wrist rather than moving the whole arm around (as in the case of G5 and Ergo 525.) The symmetrical design allows both right-handers and left-handers to play, unlike in G5 and Ergo 525, which have been designed only for the right-handers.
