Sensor Accuracy test

The Corsair Ironclaw RGB is equipped with a Pixart PMW3391 optical sensor which gave fairly smooth results with the Mouse Tester software. We tested this using different DPI settings: 500, 1500, 2000 and 3000 respectively. There were few irregularities within a few milliseconds at 1000hz polling rate which you can see with the charts below.

Corsair iCue software

The Corair iCue Software is one of the best implementation of customizing peripherals through software in the market right now. Aside form the usual customization of the lighting effects and saving DPI profiles on the on-board memory of the mouse, the iCue software also has a surface calibration tool to help your mouse adapt to any surface.

Final thoughts

We are giving the Silver Award to the Corsair Ironclaw RGB for the following reasons: it is very comfortable for someone who has a fairly large hand, the weight is pretty  average and the RGB lighting is not too overboard. The build of the mouse is solid and it can be an all around gaming mouse suitable for different genres. I would not hesitate to recommend this mouse to anyone who is comfortable with the clawgrip.

  • Comfortable to hold and it is not too heavy weighing at 105 grams.
  • Good implementation of the iCue software.
  • Minimalist RGB lighting.
  • The Pixart PMW3391 optical sensor will perform well with any game genre.
  • Not built for every hand size/grip as this is a fairly large mouse.
