Comparison Attack Shark R5 Ultra vs A-Jazz AJ159 APEX

It is worth noting that any version of Bluetooth is able to pair devices with each other. And even if both devices have a different version, the connection will occur on the lowest of them — the protocols are interchangeable.

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.

Resolution of the sensor responsible for tracking mouse movements on the work surface. Specified in DPI — dots per inch.

The physical meaning of DPI as a whole is as follows. The sensor of a modern mouse works on the same principle as the camera matrix, and consists of pixels. And DPI is the number of pixels that fall on 1 inch of the underlying surface (length or width), "visible" by the sensor.

It is believed that more DPI means a more advanced sensor and mouse in general; nowadays, models for 3500 – 5000 DPI, 12000 DPI, 16000 DPI even more are not uncommon. In a way, it is — high resolution contributes to accuracy. However, the only thing that is directly determined by this indicator is the speed at which the cursor moves across the screen: the higher the resolution of the sensor, the greater the number of pixels that the cursor will move when the mouse itself moves a certain distance. At the same time, it is worth recalling that too high a speed is even more undesirable than too low. So the real need for high DPI ( 1000 and above) arises mainly when working on large screens (4K resolution and more); for more modest displays (HD and Full HD), smaller values are often enough.

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 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 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.

Unlike models with an unperforated body, the body of such manipulators is perforated in the form of a honeycomb with characteristic holes. This solution makes the device lighter, which makes it more maneuverable. Also, the use of perforation of the body is aimed at improving perspiration drainage during long-term intensive use of the manipulator.

— USB receiver. A device that is found only in models with wireless connectivity. Such a receiver is connected to the USB port of a computer or laptop, and communication is carried out through it. This is the way all mice with a radio connection work, for them the presence of a USB receiver in the kit is almost mandatory. At the same time, this accessory is also found in the Bluetooth model — in them it plays the role of an adapter for equipment that is not equipped with its own Bluetooth modules.

— Replaceable legs. Legs are small protrusions on the bottom surface of the case, on which the mouse rests, standing on the work surface. They reduce resistance, allowing the device to slide freely in any direction, and also compensate for minor irregularities to a certain extent. However, due to constant friction, the legs are subject to heavy wear, over time they wear out or may come off. Thus, modern mice may come with interchangeable legs; such a complete set means that regular overlays can be easily removed by the user.

— Interchangeable side panels. A feature found primarily in game models (see "By Direction"). At the same time, the purpose of removable panels can be different. So, in some models, they are used to fine-tune the width or overall shape to the user's hand. In other devices, rearranging the panel allows you to change the functionality — for example, install four side button...s instead of two, providing additional features in games (and return the panel with two classic side buttons back while surfing the Internet and other everyday tasks). Such nuances should be clarified in each case separately.

— Replaceable top panels. Additional components that can be installed in place of the standard top of the mouse to change its appearance or ergonomics. Their support is implemented in some models of gaming mice (see “Direction”). Replaceable top panels provide the ability to customize the mouse to suit individual ergonomic preferences, and they also serve as a stylistic element in the design of the manipulator.

— Rug. Mice that use the mouse pad as a power source are required (see "Power"), but this accessory can also be supplied with more traditional models. In the latter case, it is worth clarifying what material the pad is made of, what dimensions and design features it has — these points may not meet the user's requirements, in many cases it is more convenient to buy an underarm pad separately.

— Case. The cover will be appropriate if you need to regularly move the mouse from place to place (for example, for frequent competitions or with a work laptop). In a protective case, your “rodent” will not be afraid of external damage to which a mouse can be subjected even while in the personal compartment of a backpack.

— Additional switches (mics) — for example, spare switches of the same type as regular ones, or interchangeable ones that differ in characteristics.

— Interchangeable side buttons. Separate side buttons that can replace regular ones. These may be keys of a different shape or spare parts of a similar design.

— Stickers. Decorative stickers that allow you to personalize your device, giving it an original look.

— Additional cable. A replacement wire that differs from the main one in length and/or other characteristics (for example, the presence / absence of a braid).

— Headphones. Gaming computer headphones supplied with mice of the corresponding specialization (see "By Direction").
