All fired up, the Attitude One Rapira Elite definitely looks like it means business. You can change the color of its lighting elements in the driver suite. You can also turn them off completely by using the on/off button on the bottom of the mouse. At around 150g, the mouse pretty much weighs as much as the Mionix and Func. That and its almost perfect ergonomics make it a very pleasant mouse to use for general work.
When it comes to gaming, it is no slouch either. The ADNS-9800 sensor tracks well at up to pretty high speeds, though it does not feel as precise as the Avago ADNS-3090 due to the sensor's inherent positive acceleration issue.
The fact that the sensor is placed a bit closer to your palm than on the Mionix Naos makes a huge difference. Articulate with your wrist and the mouse will not track the same distance as mice with a perfectly centered sensor.
The buttons work well. Buttons on the side work perfectly, but the scroll wheel with its random tactile feedback is a miss, which is a shame since everything else except for the way the sensor has been placed is so very close to being perfect. I personally enjoy the Rapira's ergonomics slightly more than those of the Mionix Naos, which has been my benchmark for quite some time now.
The teflon feet under the mouse perform incredibly well, giving you a good glide on both hard and soft mats. We tested the Rapira on CM Storm's newest crop of gaming mats, and it performed very well on those. The Feenix Dimora mat also yielded good results.
Driver
The driver suite allows you to customize pretty much any performance aspect, and you can even add custom macros. It is pretty easy to navigate and adjustments are quickly applied.
