bit-tech published a review of the SteelSeries Ikari mouse and SP mousemat
The Ikari is one of the best mice I've ever had a chance to look at – and because drinking tea at your desk is a constant hazard for me, I've looked at more than my fair share of mice. It ranks up there with the Logitech G5 and the Razer DeathAdder.SteelSeries Ikari mouse and SP mousemat Review
It has two problems though – specifically and only two. First, the enforced ergonomics on it mean that it won't be suitable for all hands and grip types, so you'll definitely want to go hands-on with a demo model before you buy it. Secondly, the two thumb buttons are a tad too small for my taste. Occasionally your thumb will have to search for the right place to push.
Despite that though, the Ikari is still easy to wield and will suit most gamers down to a tee without forcing you to pay through the nose for features you'll never use. If you're / /really bothered by how heavy your mouse is then you may want to look elsewhere, but if you're man enough to admit that you don't really mind then the Ikari is the mouse for you.
