4D wheel
The presence
in the mouse of 4D-wheels — wheels with the function of navigating in four directions. In other words, such equipment allows you to scroll the image on the screen not only up and down, but also left and right. The specific implementation of this function may be different: in some models for horizontal navigation, the wheel can tilt to the sides, in others, switching between horizontal and vertical scrolling is carried out using a separate button. However, anyway, this feature expands the functionality of the mouse, while the 4D wheel is cheaper and takes up less space than two separate wheels (see "Number of scroll wheels").
quiet click
This feature means that the mouse keys, when pressed, sound much quieter than most "rodents". This is not necessarily completely silent operation — the sound may be present; but there are also absolutely silent models. Anyway,
"quiet click" can be a real lifesaver in situations where normal button clicks are undesirable — for example, if the mouse has to be used intensively at a late time, or if the user or others are very annoyed by clicks. However, note that the presence of a quiet click is indicated based on the manufacturer’s statements, and different brands may invest different meanings in the concept of “quiet”. So if the minimum noise level is critical for you, you should clarify the features of the selected model from additional sources, for example, video reviews or reviews.
Battery time
The operating time of the mouse powered by replaceable elements (see "Power") on one set of batteries.
The operating time in this case is quite approximate: it is indicated for a certain average mode of use. The actual battery life may turn out to be either less or more than the claimed one, depending on the specifics of the application; in addition, the quality of a particular brand of batteries greatly affects the operating time. Nevertheless, this is a fairly reliable indicator, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed operating time is usually quite consistent with the difference in real battery life when using batteries of similar quality.
It is worth saying that modern battery-powered mice have pretty solid battery life, measured in months; in the most "long-playing" models, the operating time is about 36 months (that is, 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.
