Our review


The Kain Aimo 120 is at the heart of the new Kain range from Roccat. For the occasion, the manufacturer has revised the design of its mice and added new switches called Titan. They promise “the perfect click” with a foolproof reactivity. The new Owl-Eye 16k optical sensor also appears on these models.

The Kain Aimo 120 is a wired mouse with 6 buttons with RGB backlight (AIMO compatible). It is launched at a price of € 69.99.



Roccat is trying a new design for its Kain range (not to be confused with Khan, the manufacturer's helmets). The Kain Aimo 120 breaks with very ergonomic (Kone) or ambidextrous (Kova) shapes. Here we have a mouse with a relatively classic look, but with angular shapes on certain parts, far from the very rounded elongated profiles that we often find. This model is also a bit high compared to other models of this type (124 x 65 x 43 mm approximately). This mouse benefits from a very good manufacturing quality. The set is robust, there is absolutely no lack of finish. The mouse is relatively light (89 g) even if we find much lighter at present.

The Kain Aimo 120 is an intuitive mouse to take in hand. It is limited to right-handers. The feelings of comfort are quite good (in palm, claw and fingertip grip) and its weight is well distributed. There are still a few points for improvement, especially for large hands like ours (20 cm in length, 10 cm in width). First of all, the angle formed between the left side part and the back / top of the mouse is a relatively marked one and can prove to be annoying during long sessions. We would have preferred a more rounded and “elongated” profile. In addition, the shape of a more "packed" hair on the back of the mouse does not perfectly fit our hand, especially in the palm grip position. We had the opportunity to test the mouse with a few medium-sized hands and the observation is the same.

This mouse opts for a relatively classic 6-button configuration: two main clicks, two side clicks on the left, a wheel and a button to switch between the different sensitivity profiles. The Kain 120 Aimo is also compatible with the Easy-Shift [+] function which allows you to assign a second function to each button of the mouse. Their positioning is fairly conventional and intuitive. However, we have a small reservation in our case since the right side button is a little difficult to access.

We must retract the thumb significantly (and therefore bend the wrist a little more) to reach it and avoid a hazardous trigger on the left side button. However, there is nothing to say about the experience provided by the Titan switches. They are indeed extremely reactive and lively, it is a real pleasure to use them, both on very demanding games and on other applications. They produce a small, rather sharp and “dry” click, the sound level of which is still acceptable.

Putting aside the RGB backlight, the notched dial on the Kain 120 Aimo looks pretty conventional. That said, it is extremely precise and pleasant to use. The passage of the notches is both well marked and fluid, the click of the wheel is also very responsive. No need to force to engage it. The rebound is very well controlled. This mouse clearly does not suffer from the soft wheel syndrome. However, it only offers vertical scrolling.

Below the Kain 120 Aimo are two large “banana” shaped runners. There are no replacement pads supplied. Gliding is guaranteed and perfectly fluid. No particular surface can resist it, but we still recommend combining it with a fabric mat to get better sensations and more precision. The connection is made via a thin, braided 1.8 m USB cable. This is not particularly a problem, although we would have liked a slightly less rigid constitution to completely forget it.



The Kain 120 Aimo is one of the first mice to use the new Owl-Eye 16k / PMW3381 sensor made by Pixart (max acceleration of 50g, max speed of 400 fps). This is an advanced version of the excellent "all short" Owl-Eye (PMW3360) found on previous models of the manufacturer such as the Kone Aimo or Kone Pure. Unsurprisingly, it is perfectly up to par with top precision and responsiveness. During our long testing period, we never managed to fault it. If not on glass or reflective surfaces, it works on the vast majority of surfaces. However, it is better to favor a good mouse pad for optimal performance in the game.

As the name suggests, the Owl-Eye 16k can go up to a sensitivity of 16,000 dpi. A value by really usable since one loses clearly in precision while going up to such levels. Most players prefer a sensitivity between 400 and 1000 dpi.



The Kain 120 Aimo will delight right-handed players looking for a very swift mouse with a powerful sensor and very responsive buttons. The competition is very proud in this sector, there are nevertheless models with 6 buttons a little more comfortable suitable for all hands and also efficient at a similar price. We can cite for example the Model O and the Basilisk.
