Comparison Logitech MX Anywhere 2 vs Logitech MX Anywhere

The type of connection used by the mouse.

All types of mouse connection can be divided into wired and wireless. There are also combined models that allow both methods; however, for a number of reasons, they have not received much distribution.

Wired mice can vary in connector type; however, the universal standard nowadays is USB, other options are much less common (see "Cable" for them). Anyway, such mice are much cheaper than wireless counterparts, moreover, they do not require batteries / accumulators and have an almost unlimited lifespan. On the other hand, the wire restricts mobility and can be inconvenient when connecting, especially if the computer is located far away or in a hard-to-reach place.

Wireless devices, in turn, can connect via radio, Bluetooth, or Wi-Fi ; in some models, two options are combined — at the user's choice, (usually radio and Bluetooth). Regardless of the interface used, all such models are more convenient than wired ones due, in fact, to the absence of a cable; and their range is at least a few metres, so a wireless mouse can also work as a kind of remote control. At the same time, a wireless connection is more expensive than a wired connection, and besides, it requires autonomous power supply — as a result, the per...iod of continuous operation of the mouse is limited.

As for the different types of wireless connection, here are their features:

— Radio. To connect over the air, usually, a wireless adapter is used, which is connected to the USB port of the computer. This method is convenient in that it can be used with any computer, including systems that do not have built-in Bluetooth or Wi-Fi modules. The disadvantages of this option include the fact that the adapter requires a free connector; as a result, with a small number of USB ports, difficulties can arise. However, this moment, if necessary, can be easily corrected by connecting a USB hub; so it is this connection method that is most popular among modern wireless mice.

— Bluetooth. The main advantage of this connection method is that many modern devices — laptops, most monoblock computers, smart TVs, etc. — have built-in Bluetooth modules. Thus, you can connect the mouse to such equipment directly, without occupying hardware connectors. And for PCs not equipped with internal Bluetooth modules, appropriate adapters are available (which may even be included with the mouse). In addition, some advanced models with such a connection are able to remember several Bluetooth devices at the same time and switch between them literally “with the touch of a button”. The Bluetooth communication range is at least 10 m with line of sight.

— Wi-Fi. A rather specific option, which is extremely rare — in certain models of laptop mice (see "In the direction"). In many respects it is similar to Bluetooth — in particular, it is designed mainly to work with built-in modules and allows you to use a mouse without occupying hardware connectors. At the same time, the range of communication via Wi-Fi is much greater. On the other hand, this advantage is not of fundamental importance, and on the technical side, the creation of Wi-Fi mice is associated with certain difficulties. That is why this type of connection has not received distribution.

Mouse support for Multi-Device technology.

This technology is found exclusively in models with wireless connectivity (see “Connection type”). It allows you to pair the mouse with several devices simultaneously and quickly switch between them without fiddling with the settings every time; in many models, such switching is carried out literally at the touch of a button. Thanks to this, you can, for example, easily use the mouse with both your home computer and a TV running Android TV, connecting to one or another device as needed.

Note that it would not hurt to clarify the specific features of the Multi-device separately. First of all, this concerns the number of simultaneously supported devices.

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.

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 type of power used by the wireless mouse (see "Connection Type").

Modern mice can be powered by replaceable cells, by a built-in battery, or by a mousepad. The first option is good because dead batteries can be replaced with fresh ones in a matter of seconds, no need to waste time charging. At the same time, replaceable cells are sold both in the form of disposable batteries and in the form of rechargeable batteries, which gives the user a choice: to buy inexpensive batteries regularly or to spend money on a battery (s) with a charger once. Here are the main sizes of such elements found in modern mice:

— AA. Widely known "finger" batteries. A fairly common option, although less popular than the smaller AAA — in fact, because of the larger size, poorly suited for compact mice. On the other hand, AA cells have higher capacitance. The number of such batteries can be different, most often there are models for 1xAA or 2xAA.

— AAA. "Mini finger" or "little finger" batteries. More compact than AA, due to which they are widely used in modern mice. The capacity of such elements, however, is lower, however, mice do not consume so much energy, and even with 1xAAA power supply, battery life can be calculated not only for months, but for years. Also, there are often models on ...="/list/267/pr-15332/">2xAAA, and extremely rarely on 3xAAA.

As for other ways of eating, their features are as follows:

— Accumulator. Own built-in battery is convenient primarily because it is initially included in the package, you do not need to buy it separately. And the further operation of such a mouse does not require additional expenses — it is enough to charge it from time to time. In addition, batteries can be made more compact than replacement cells. There are two main disadvantages of such a power supply, compared with the same batteries. Firstly, this is less battery life — in the most "long-playing" rechargeable mice, the battery life does not exceed 120 days (for batteries, this is a very limited indicator). The second point is the inability to quickly remove and replace the battery. This means that with a dead battery, there is only one option — charging, and it takes time; however, many mice allow use directly in the process of charging. But if the battery fails, at best, the device will have to be carried to the service, at worst, it will be changed entirely.

— From the rug. Quite a specific option: powered by a special pad that transmits energy to the mouse wirelessly. The pad needs to be connected to a computer port (usually USB), so such mice are very conditionally wireless. One of the advantages of such models is that they do not need to monitor the battery status. On the other hand, you can use the mouse only with the supplied mouse pad; if it is missing, the device becomes useless; and freedom of movement is limited by the length of the wire. Thus, mice with such a power supply do not actually have key advantages over wired models, and they are much more expensive. So nowadays, food from the rug is extremely rare.

The battery life of the mouse (see "Power") on a single battery charge.

The operating time in this case is quite approximate: it is indicated for a certain average mode of use, and the actual battery life may turn out to be either less or more than the claimed one, depending on the specifics of the application. Nevertheless, this is a fairly reliable indicator, it is quite possible to evaluate different battery 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.

Separately, we note that the operating time for rechargeable mice is generally less than for battery-powered models, so this parameter is indicated in days, not months.

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.
