Number of buttons
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.Inertial wheel
A wheel with an accelerated scrolling mode that allows you to scroll through a large “sheet” of pages in text documents, spreadsheets or on Internet resources in just one movement.
The inertial wheel is a hallmark of a number of Logitech mouse models.
Programmable buttons
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.
Battery life
Battery life of the mouse operating on replaceable power elements (see "Power") with one set of batteries.
The mentioned operating time is quite approximate: it is specified for an average usage mode. Actual battery life may be either less or more than stated, depending on the usage characteristics; moreover, the quality of the battery brand also greatly affects the operating time. Nevertheless, it is a fairly reliable indicator, which can be used to evaluate and compare different models: the difference in the stated operating time generally corresponds to the difference in actual battery life when using batteries of similar quality.
It is worth mentioning that modern battery-operated mice have fairly substantial battery life, measured in months; in the longest-lasting models, the stated operating time is about 36 months (or 3 years).
Weight
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.
