As with any computer peripheral or accessory, personal preferences and taste come into play. Ambidextrous (i.e usable by both hands) mice are naturally preferred by left-handed users in a right-handed society that we live in, but also the symmetrical shape gives perfect weight distribution and balance that a serious FPS gamer demands.
There is a attractive looking white Steelseries logo on the body which is illuminated during operation. Other than the obvious drawback of being a fingerprint magnet (not so obvious in this case because its black), the glossy version has the advantage over the traditional rubberized surface of not being stripped off by friction and sweat, keeping the original look intact even after months of intensive use.
On both sides of the mouse, we get two strategically placed side buttons for your thumb, reminiscent of the famous Microsoft Intellimouse Explorer 3.0 design that is still the de facto choice of many old-school gamers today.
On top, there is a middle button which is configured by default to be a CPI high-low toggle, and a partially illuminated scoll-wheel. The latter has just the right pressure and distance between each step to prevent accidental scrolling mishaps. Most importantly, the primary left and right click buttons takes an equal amount of force to actuate and responds quickly in rapid fire tapping scenarios for those soul gratifying headshots.
Below, we see a trio of teflon feet taking up 16% of the transparent base. The Avago ADNS-9500 laser sensor is mounted right smack in the middle, which is a good thing as it avoids unwanted Z-axis liftoff issues.
The USB cable attached to the Sensei Raw is stylishly braided (prevents tangles and improves durability) but not gold-plated at the connector end.
