Kärna did an excellent job with the Boomslang's software drivers.
Version 2.0 of the drivers lets you change the sensitivity setting,
click speed, scroll rate, and button assignments. All this is
done through the nice little control panel that can be easily
accessed by double clicking on the icon in the windows taskbar.
options range in .5 increments from an ultra slow 1.0 to an
almost uncontrollably high rate of 10.0. Personally I think
it is easiest to start off at about 6.5 and slowly move up to
until you have reached a speed that fits you liking. In version
2.0 of the software, Kärna added the ability to change both
the X and Y-axis sensitivity to different rates, another nice
little feature. Best of all, you can change sensitivity on the
fly simply by holding down the 4th button and scrolling on the
are also options to change the scroll rate of the mouse wheel,
and button assignments. Setting the scroll rate is nothing special,
nor is assigning unique options to the buttons. Something that
is a little unique is that you are able to utilize all 5 buttons
for separate instructions this is definitely a plus. You can
assign either normal actions or advanced macro combinations
to each individual button.
