You know, I really like these ambidextrous mice! It makes games all sorts of messed up as I try to maneuver and attempt to shoot at things as I aim left handed. For a right hander, I find most mice to just feel funny in my left hand, but with the mirrored design concept of the SteelSeries mice, both right and left handed users can have the same advantages. With the Kinzu V2 Pro Edition, those advantages are the Omron switches giving you accurate responses over the long term use of the mouse. Then you have a similar Pixart sensor that comes in the Kana, but it has been tweaked with some features being listed as less, but is still plenty for an enjoyable time at the desk with this mouse.
For my personal usage in games and while writing and surfing the web, I prefer a mouse to at least offer a back page button; yes, I am that lazy to not want to move up to the arrow. That being said, the Kinzu fell short from being a mouse I will personally use day to day. However, the hours in game and doing basic things was no less enjoyable, I just had the retrain my brain to remember there is that arrow at the top of the browser window. While in game I loved the simplicity of the design as I found myself fumbling around trying to remember which button is my knife and which button is for my grenades. Just having basic fire controls, scoping ability and the on the fly CPI adjustment will make it enjoyable for most users that are into what matters in mice.
The two things that make me the happiest about recommending that you get your hands on your own Kinzu V2 Pro Edition so you may better enjoy your gaming experience, are the pricing and the ready to deliver now availability I am seeing. There will be no waiting other than the time it takes from the purchase to when it arrives to your door. As far as the pricing goes, for around $45, I don't see how you are going to find one that is this comfortable, easy to use and program, ambidextrous for all those lefties out there and still get top-end components included with that rock bottom pricing!
SteelSeries offers those on a budget a very versatile and useful tool to improve their gaming on a level very close to its larger brethren.
