Comparison A-Jazz AJ159 Pro vs Attack Shark X3

The direction the mouse is facing. Specified only for models with additional specialization or design features — namely, for laptop, gaming and vertical mice. Here are their main features:

— Laptop. Mice well suited for use with laptops. Most of these models have compact dimensions — the length of the case in them is less than 110 mm, and often less than 100 mm. This makes it easy to transport along with the laptop. And larger devices are considered laptops if such specialization is somehow indicated by the manufacturer. In addition, this category includes most models with a Bluetooth connection (see "Connection type") — such a module is found in almost any modern laptop. And wired laptop mice can be equipped with a wire winding system that allows you to adjust the length of the cable for different situations and twist it compactly for transportation.

— Game. Mice designed primarily for use in computer games and intended for gamers — including professional e-sportsmen (although the price category and capabilities of different models, of course, may vary). Such devices are often made in a characteristic "aggressive" design, with unusual patterns, logos, coloured backlighting (in some models — with effects), etc. On the functional side, gaming mice are distinguished primarily by increased sensor accuracy, as well as the presence of various specialized feat...ures — such as additional buttons with the ability to “attach” certain game actions or even a sequence of actions to them, a triple-click (“queue”) button, a sniper button, DPI switching (see below), weight adjustment, etc. Note that narrow the specialization of such models can be different: there are both universal gaming mice and devices optimized for a specific genre (shooters, RPGs, etc.) or even a specific game.

— Ergonomic (vertical). Mice of a specific design: the surface on which the hand is placed during work is not located horizontally in such models, but with an inclination to the right (in left-handed models — to the left). As a result, the body height is noticeably greater than that of traditional models — hence the name "vertical". And the user's hand actually covers such a case from two sides: on one side (on an inclined surface) there is a palm, on the other (in a special recess) — a thumb. This position of the hand is considered more natural and comfortable than the classic horizontal position, it reduces the load on the joints and ligaments, thus reducing fatigue and the likelihood of carpal tunnel syndrome and other disorders. Vertical models are well suited for those who have to work at the computer for a long time — except that it may take some time to get used to the unusual shape after a traditional mouse.

The ips (inches per second) parameter is the linear speed of mouse movement, expressed in inches per second, at which the manipulator's sensor is able to read the surface. In top models, the maximum mouse movement speed often reaches 400-600 ips, but devices with ips in the region of 200 are more common.

The polling rate shows how often the mouse sensor exchanges data with the computer about cursor movement. This parameter is measured in hertz (Hz), with one second being taken as the unit of time for its assessment. The smoothness and speed of cursor movement directly depend on the polling rate of the sensor. Directly connected to it is the mouse response time — this is the time interval required for the signal about the manipulator's movement to reach the display of the cursor position change on the screen. Response time is measured in milliseconds (ms). The higher the mouse's "hertz rate," the lesser the response time it demonstrates. The most common value can be considered 1000 Hz with a response time of 1 millisecond. For competitive games, attention should be paid to faster mice, including 2000 Hz, 4000 Hz, and 8000 Hz. Values below might negatively manifest just in gaming scenarios.

The switches in a mouse indicate which specific switches are installed under the main buttons, such as Omron, Huano, Kailh, TTC, or proprietary solutions from the manufacturer. These determine the click characteristics, actuation force, click volume, lifespan, and the likelihood of double-clicking over time.

Unlike the general switch type, which refers to the working principle—mechanical or optical—the brand and model provide a more precise understanding of the performance level. For example, two mice with mechanical switches might feel different when clicked: some may be softer and quieter, while others could be stiffer, louder, and feel more "gaming-like."

The durability of mouse switches is measured by the number of clicks the keys can withstand before they begin to show signs of wear or malfunction. Switches can have a lifespan of several million to tens of millions of clicks. In laboratory conditions, this parameter is checked using special testing machines, which diligently press the keys the required number of times, on the basis of which a verdict is made regarding the approximate service life of the switches.

The presence of programmable buttons in the design of the mouse. In this case, the buttons mean not only the keys, but also the scroll wheels, which are usually able to work on pressure.

Almost all models with this feature are gaming (see "By Direction"). Usually, programming is carried out using special proprietary software, while the functionality of such a setting may be different. For example, in some models, only one action can be tied to one button, in others — a whole series of actions (such as a combination of attacks in an RPG). Often, it is possible to configure one button for different actions in different games.

However, this feature provides an additional convenience: the mouse keys are right at hand, and it is usually easier (and faster) to use them than to reach for the button (s) on the keyboard.

Additional features of the cable that the mouse is equipped with.

These features may include a winding system, a detachable wire, and a braided wire(however, most modern mice still have a cable without a braid). Here is a more detailed description of all these features.

— Retractable. Wire equipped with a special coil for winding. This feature greatly simplifies transportation: during off-hours, the wire is as compact as possible and does not get tangled, and when used, it can be unwound to the desired length (usually the coil allows this possibility). All this is especially important for laptop mice (see "In direction") — in fact, most models with a wire reel fall into this category.

— Removable. Wire that can be detached from the mouse. Almost all mice with two connection options have this feature — wired and wireless: when working in a wireless format, the cable can be removed so that it does not interfere. However, there are also purely wired devices with such a cable — mostly laptop devices, where the wire is removed for ease of transportation. Also note that most often a universal connector like microUSB is used to connect the cable, so if necessary, the wire can be replaced with another one — for example, a longer one.

— In a braid. The presence of an additional braid on the mouse cable. This feature makes the wire more d...urable, reliable and resistant to bending. On the other hand, braid tends to accumulate dirt and fray when worn; because of this, the wire sheath loses its presentation faster than in mice without a braid. Yes, and such a wire is more expensive than a regular smooth one.

The length of the cable that is equipped with a mouse with the possibility of a wired connection (see "Type of connection").

When choosing this parameter, you should first of all take into account the distance from the manipulator to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get tangled at hand and create inconvenience. As for specific values, the most modest wire length in modern mice is 1 m or less ; such devices are intended mainly for laptops. Most desktop manipulators come with cables that are 1.1-1.5m or 1.6-2m long, with some models running longer than 2m.

The battery capacity in a mouse affects how long it can operate without recharging and determines how often the device will need to be charged. Although manufacturers usually specify the operating time, the capacity helps assess the battery's resource under intensive use or when additional features, such as backlighting, are activated.
