Sensor

The Kone AIMO features a high-end optical sensor called the "Owl-Eye"; at least that is its codename as it is actually a PMW3361, which is based on the PMW3360 made by PixArt. This sensor is pretty much perfect; it's raw, responsive, and works flawlessly without any malfunctions. Its nominal maximum tracking speed and acceleration values are 250 IPS and 50 G. The MCU is a 32-bit ARM Cortex-M0 based LPC11U35F made by NXP.

The resolution can be changed from 50–12,000 CPI in increments of 50 CPI. The polling rate can be set to 125, 250, 500, and 1000 Hz. If you like angle snapping, you can turn it on, but I always advise against using it.

The default lift-off distance is low enough; it didn't track from one DVD in height (roughly 1.2 mm) at the default setting on a black cloth mousepad. If you have issues with this being too low, you can set a higher value in the Advanced Settings tab of the software.

Paint Test

There isn't any jitter on the reasonable CPI steps, or angle snapping and measurable (or audible) sensor lens rattle.

CPI Divergence

The CPI accuracy is relatively good as deviations are rather low. Please note that this test isn't 100% accurate, but it resembles reality.

Perfect Control Speed

The PMW3360 variants have an insanely high PCS; they stop tracking above 7 m/s, which is quite astonishing. I could reach around 4.5 m/s maximum on a 450 mm wide mousepad, but that took a very very powerful swipe, so there is no chance of you hitting these numbers while playing a game, even on ridiculously low sensitivities.

Speed Related Accuracy Variance

This test shows the sensor's accuracy at different speeds. You can see me doing a fast swipe to the right before I slowly slide the mouse back to its original position.

Now, there are some displacements here I wouldn't call negligible, but in my opinion, the sensor and firmware are just fine. The mouse is big and heavy, while my hands definitely are not. My hands were quite jerky by the end of each swipe, so even though I am not entirely sure, this had things going off a bit.


Here's the same test done with the MouseTester software; everything seems quite perfect here.

Polling Rate

The set polling rates are nice and stable; there are no errors here whatsoever.

Input Lag

The Kone Pure Owl-Eye is equipped with the same sensor, and it has shown the very same input lag as the Kone AIMO. All PMW3360 variants have the same "issue", which is roughly +2 ms input lag above 2000 CPI. If you play competitively, it's best to stay on or below that value. If you're gaming casually and need the high CPI for a specific reason, just feel free to set anything.
