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).
