Comparison A4Tech G9-500F vs A4Tech G10-810F

The range of the wireless connection provided in the mouse (see "Connection Type").

Almost all modern wireless models work confidently at a distance of at least 2 – 3 metres. So you need to pay attention to this parameter mainly when you plan to use the mouse at a greater distance from the computer — for example, when working with a projector at a presentation. At the same time, when evaluating the range, note that it is indicated for perfect conditions: the absence of interference and obstacles in the signal path, the full charge of the battery in the mouse, etc. In fact, the communication range may be somewhat less, so when choosing, it is worth taking a certain stock. Nevertheless, according to the claimed range, it is quite possible to evaluate the practical capabilities of different models and compare them with each other.

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 number of buttons provided in the design of the mouse. However, the term "buttons" can also refer to specific hardware solutions — for example, a solid touch area used in many Apple mice counts as two buttons, because. it is divided into two working areas. But the clickable wheels, as well as the power button, are not taken into account in this calculation.

The minimum number of buttons for modern mice and other similar manipulators is two : this is the number that is necessary for comfortable work in most modern operating systems. If there are more than two keys, this means that there are additional buttons responsible for specific actions. So, even relatively inexpensive devices can be equipped with 3 – 4 buttons ; in addition to the 2 main buttons, they can have, for example, 2 side thumb keys, or 1 double/triple click button (see below). Solutions for 5 – 6 buttons are extremely popular nowadays; among them are many gaming mice, where the mentioned thumb buttons are supplemented with a double / triple click, a sniper button and/or a DPI switch (see also below about these functions). And in the most multifunctional models, 7 – 8 buttons and even more can be installed. In some cases, this number exceeds a dozen and a half; such mice are usually gaming devices designed for RPGs and other simil...ar genres where it is important to have a wide range of actions at your fingertips.

The presence of the mouse side buttons — under the user's thumb.

The traditional, most popular option is two buttons, which by default are responsible for the “Back” and “Forward” commands in the browser, system file explorer, etc. There are more of these buttons in gaming mice; some of these models even have an interchangeable side panel that allows you to install a different number of side keys, as desired.

Anyway, the side mouse buttons provide additional convenience and expand the list of features available from the device. At the same time, the buttons are always at hand, in fact, in instant access. This is especially handy in games: some frequently used actions can be tied to the side keys, such as reloading or a special attack. However, even in everyday use, it is much easier to press a button on the mouse than to move the cursor to the Back or Forward icon every time in the same browser.

A separate button that allows you to change the working resolution of the sensor on the fly without going into the software settings.

Recall that the sensitivity of the mouse and the speed of moving the cursor around the screen depend on the set DPI. For different tasks, the optimal DPI values \u200b\u200bcan also be different: for example, when working with graphic materials or maps on a large screen, high sensitivity is often convenient, and in a shooting game you may need to reduce it — for accurate aiming. Setting the sensitivity using the DPI switch button is as simple and convenient as possible: it is available regardless of the currently running programme, including in situations where it is difficult or impossible to enter the software settings of the mouse (the same games can be used as an example). Also note that the DPI level indicator can be built into this button (see below).

The presence in the mouse of its own built-in memory.

The main and, in fact, the only way to use such memory is to store various advanced settings (for example, the functions of programmable keys, or even entire user profiles for various games or other tasks). This feature is relevant mainly for gamers, so almost all models with this feature are gaming.

The total weight of the mouse. For models with a wired connection, usually, it is indicated without cable, and for devices with weight adjustment (see above) — without weights.

This parameter is important primarily for professional gaming applications, although it is often relevant for ordinary users. Theoretically, less weight promotes speed and reduces fatigue. At the same time, in fact, much depends on the personal habits and preferences of the user: a mouse that is too light may “not be felt in the hands” and not give familiar feedback. Therefore, although most mice have a lower weight limit of 60 – 80 g, however, even among professional gaming models there are much more massive devices — 120 – 140 g or more. The lightest variety of "rodents" is laptop (see "In the direction"), among them devices come across and less than 60 g.

Also note that the weight to some extent depends on the size and “tricked out” of the device, but there is no unambiguous dependence here: models similar in size and functionality can differ markedly in weight.
