Durability

This mouse is quite durable I cannot identify any durability problems on this mouse besides the amount of stuff on it. The fact that it is so feature rich means that there are several more details that can break down over time. Everything seems well bonded together and well constructed. The looks of the mouse will be retained through its entire life because it is made from solid color plastic, however, the little SteelSeries logo might rub off in time.

Comfort

Comfort wise this is definitely one of the better mice. The sleek ergonomics design of the Ikari makes it a thrill to use even over an extended period of time. Because the ergonomics fit so well means that you use less force to maneuver the mouse around and make it easier on the hand. SteelSeries has hit a good compromise between shape and size with the Ikari and I am sure that most people will be able to get an extremely comfortable gaming experience with the Ikari. The only downside to this neat ergonomic design is that the mouse is only for right handed people.

As far as button placement goes this mouse is one of the better with thumb buttons easily accessible. It is clear that SteelSeries has designed this mouse with people in mind who lay their hand on top of the mouse.

It is one of the most comfortable mice out there right now alongside the Logitech MX-series and Microsoft IntelliMouse Explorer 3.0. The Ikari resembles the design of the Microsoft mouse somewhat, but is generally sleeker and a bit easier to grip.
