Clicking on the key will increase the size of the mouse and decrease as well. Therefore you can easily change the grip type of the mouse from palm to claw and claw to palm.

You can fix the palm rest in any position you like by the help of lock. At the bottom of mouse there are holes and notches that don’t allow it to hang in lifted position. The palm rest move along hard skids of the base.

Mouse Buttons

4 essential parts of the mouse are at the upper part. 2 main keys are separated, and left key is less as compared to the right. An important feature of this mouse is OMRON switches used in the mouse buttons that can tolerate up to 20 million clicks. Additionally, switches are adapted to highest possible performance of APM, that in turn gives excellent outcomes and maximum durability.

At the left of main keys is edge with additional button to change the color related to the selected profile mode.

At the middle of the main keys is the scrolling wheel that has visible rubberized edges. Behind wheel is a key for changing sensitivity on the fly. You can change 100 to 5000 DPI and that’s covers almost all games genres.

The side panels have a soft-touch coating and are fastened to the screws for convenience. If necessary, they can be dismantled for maintenance or cleaning. On the left panel at the top there are two mechanical keys (forward, backward), slightly ahead there is a round button of precise aiming.
The left lateral part smoothly passes into the base under the thumb.

Mouse Base

The base of the mouse is made of a matte plastic of red color, which greatly facilitated the design of the mouse to 90 grams. Due to the transparency of the lower part, the whole base appears to be illuminated, although lighting is only done at two points.

Six Teflon legs perfectly slip on any surface and perfectly cope with the task. The mouse has an asymmetric shape and is intended only for right-handed users.

Mouse Sensitivity

In the center of the base of the mouse, the optical sensor PIXART® PMW 3310 is noticeable. Many are accustomed to finding Avago Technologies sensors in the manipulators. However, the gaming sensors PixArt Imaging Inc. have their considerable segment of users and are in demand among a great number of well-known cyber players.

According to technical data, the optical sensor PMW3310 can be contrasted with the Avago ADNS-A3080 / A3090 sensor. In our case, a similar lens (ADNS-2120-001) is used in the PMW3310 sensor. The main advantages of the sensor can be called the PixArt oscillator, reduced power consumption, and, of course, the ability to accurately monitor the minimum movement. The sensor operates in the range of 100 to 5,000 dpi with a maximum acceleration of 30G.

The backlight is clearly visible in four zones: the name of the mouse on the back, the changeable sensitivity on the back side of the left border and the backlight at the base in the front and under the back.

Mouse Connectivity

The connecting cable has a length of 1.8 meters and has a fairly flexible, but strong black cloth braid. The end is crowned with a gold-plated USB connector.


The software hasn’t undergone any significant changes. It is fully translated into Russian. It can also be downloaded from the manufacturer’s website. In total there are three profiles (red, blue, purple), the switching of which is on the edge near the left main button.

In the main window in the “Programming” tab, you can change the actions of the nine buttons for each profile. This is done quite simply by dragging the finished icons from the panel on the right to the selected key. Here you can quickly edit the recorded macros with a convenient editor
In the “sensitivity” section, you can fine-tune your “rodent” in many ways. For example, adjust the sensitivity of the mouse in four ranges or pump the sensor with a software booster. You can turn off the DPI switch and set up sniper mode.

For more precise settings, you can use the change in polling frequency, the height of the sensor detachment and fixing the angle of inclination. For large aesthetes, you can turn off the backlight.
