Summary: I purchased my first Ikari Laser mouse in September 2008. It lasted until October 2012 when it started to act a bit funky, probably a laser problem. I loved this mouse so much that I bought two more, one for daily use and the other as a backup. The mouse (for righties only) fits my hand perfectly, like a glove. It is superb for gamers with precision tracking in every game that I've played. It does not use any drivers other than the Windows mouse driver.
Summary: I think this may be the best that steelseries has to offer. The shape of the mouse is unlike anyother and so far I have not found anything that beats it. The improved from the optical texture, now leaves nothing to be desired. Being able to adjust the DPI one increment at a time is an actual, valuable feature and not a gimmick. The thumb buttons are perfect and the mouse has a perfect sensor that has shown no weaknesses.
Summary: As of this review I only have about an hour of game time on the mouse, but that's all one needs to be impressed. To keep it short and sweet, other reviews are correct regarding the mouse's size and weight. If you have large hands, you're probably not going to like this mouse. My tiny little hands can just manage to lift and reset it without hitting the side buttons. The quality of the materials is excellent and the tracking and accuracy are the best I've seen.
Summary: The IKARI laser mouse has been the best mouse I have ever used. I have always had problems with hand cramping prior to using the Ikari and have not experienced the same problems since. The traction and precision is excellent and I have received numerous compliments from friends on how it looks and feels. I have definitely become accustomed to using this mouse and will never use another one again.
Summary: It's a bit pricey, but good value. I'm not a gamer, but spend a lot of time with graphics programs, like Photoshop. The shape suits my (somewhat large) hands and is comfortable for long periods of use. It supports my hand in a relaxed, comfortable position, and I find it easy to control for both fast and precise movement. The ability to switch the mouse sensitivity on the fly is a real advantage when changing from browsing the web to doing fine detail work in photoshop.
Summary: I must say that SteelSeries Ikari Laser Mouse is the best mouse on the Earth. As soon as I put my right hand on it, it literally feels like I'm NOT holding a mouse. My right hand melts on it. And also, the mouse's left and right buttons are very easy to click, so RTS players who play StarCraft:Brood War or StarCraft 2 will feel no discomfort in their right fingers when using this mouse.
Summary: I have been using Microsoft and Logitech mice for past many years - Just recently I changed the position of my Cisco-Linksys closer router to my system and my Wireless Mouse 8000 started giving me problems, like, when WiFi was in use the mouse cursor starts to slowdown and scrolling and pointing became sluggish. I do not play any games on my System (I have a PS3!).
Summary: Pro's: Driver-less Highly configurable Good hand "feel" Large, fits my hand very well. Very sensitive laser Large contact pads on the bottom help it to glide over surfaces. Con's: could use more buttons This will be the last mouse i buy for awhile. It's solid, it feels good in my hand and works very well. I had no idea how much I'd appreciate the driver-less design until i used it. That's a really nice feature.
Summary: This mouse is quite sensitive. At first I clicked the right mouse button a lot by accident (just letting your finger rest is almost enough to click it). Scroll wheel works fine, and middle clicking is actually really easy (it doesn't scroll when you try to click). High/Low sensitivity is great for Boot Camp (Windows uses lower sensitivity than OS X). This mouse is very light, and tracks very well on all kinds of surfaces.
