As of late, the proliferation of USB devices on the market has increased steadily. With the ability to support large chains of devices, the expandability of the USB bus has manufacturers releasing cameras, modems, keyboards, and mice. One of the benefits the USB bus provides versus the standard PS/2 port is its polling rate (how often the port "refreshes" the position of the mouse). Set by default to 40Hz by Windows 98, the PS/2 port was only useful to gamers who increased the speed to 80 or 100Hz (which unfortunately taxes the CPU). On the other hand, the USB bus samples at a default frequency of 125Hz. Again, these numbers may not mean a whole lot to the average computer user so we'll sum it up like this: Speed in any form (except the kind that kills and rots your teeth) is good, so by increasing the "refresh" of the mouse, you are "smoothing out" the mouse's motion.

One aspect of the Boomslang that kärna cannot be accused of skimping on is the driver set. Able to control every aspect of the Boomslang's behavior (almost like a snake charmer in that sense), the drivers that are included are not only stable and robust, but also aesthetically pleasing and very useful. For the customers that don't have USB connectivity available to them, kärna has included a built-in application called PS/2 Flex to adjust the polling rate of the PS/2 port.

As we can see, every option desirable to control one's mouse is present and accounted for. With unique features such as on-the-fly sensitivity adjustment (meaning you can adjust the setting while you're playing), the Boomslang 2000 goes above and beyond what any other mouse manufacturer has attempted.

Although we didn't come across any problems in the shipping drivers, kärna has been prompt to release drivers for PS/2 users experiencing stability problems.

Even with all of the gaming features in the world, if a mouse doesn't meet a user's strict comfort requirement, it simply won't be an attractive option (and is the reason why luxury cars come with leather seats and not concrete benches). It is this issue with which we have received conflicting opinions.
