Bluetooth version
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.
Battery capacity
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.
Battery life
Battery life of the mouse (see “Power”) on a single charge.
The battery life in this case is rather approximate: it is given for an average usage scenario, and the actual autonomy may turn out to be less or more than stated, depending on the usage patterns. Nevertheless, it is a fairly reliable indicator, allowing different battery models to be evaluated and compared with each other: the difference in the stated battery life usually correlates well with the actual autonomy difference.
In box
— 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").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.
