Comparison Logitech G903 Lightspeed Wireless Hero vs Logitech G900

The range of the wireless connection provided in the mouse (see "Connection Type").

Almost all modern wireless models work confidently at a distance of at least 2 – 3 metres. So you need to pay attention to this parameter mainly when you plan to use the mouse at a greater distance from the computer — for example, when working with a projector at a presentation. At the same time, when evaluating the range, note that it is indicated for perfect conditions: the absence of interference and obstacles in the signal path, the full charge of the battery in the mouse, etc. In fact, the communication range may be somewhat less, so when choosing, it is worth taking a certain stock. Nevertheless, according to the claimed range, it is quite possible to evaluate the practical capabilities of different models and compare them with each other.

The model of the sensor installed in the mouse. This information is indicated mainly for models equipped with high-end sensors, which are significantly superior in their capabilities to simpler solutions. Such characteristics are important primarily for gaming mice, so most of the devices for which the sensor model is specified belong to this category.

Knowing the name, you can find detailed data on the sensor and evaluate its capabilities. Note that one of the most popular brands nowadays, under which advanced sensors are produced, is PixArt ; on the market are often found, in particular, sensors PixArt 3212, PixArt 3325, PixArt 3327, PixArt 3335, PixArt 3360, PixArt 3389, PixArt 3395. The second common brand is Avago (recently owned by the same PixArt); the most popular model of this brand is Avago 3050, the simplest and most affordable representative of gaming sensors.

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.

The presence of the mouse side buttons — under the user's thumb.

The traditional, most popular option is two buttons, which by default are responsible for the “Back” and “Forward” commands in the browser, system file explorer, etc. There are more of these buttons in gaming mice; some of these models even have an interchangeable side panel that allows you to install a different number of side keys, as desired.

Anyway, the side mouse buttons provide additional convenience and expand the list of features available from the device. At the same time, the buttons are always at hand, in fact, in instant access. This is especially handy in games: some frequently used actions can be tied to the side keys, such as reloading or a special attack. However, even in everyday use, it is much easier to press a button on the mouse than to move the cursor to the Back or Forward icon every time in the same browser.

An indicator showing the current resolution of the mouse sensor.

The DPI value indicator is found only in models that allow you to switch the sensor resolution and are equipped with the appropriate buttons (see above). The indicator allows you to easily monitor the set DPI settings. Note that it does not necessarily show specific numbers — conventions can be used, for example, different backlight colours.

Wireless charging technology supported by a mouse with a built-in battery (see "Power").

By itself, wireless charging, in accordance with the name, allows you to replenish the supply of energy without connecting a cable — just install the mouse on the platform / stand of a special charger (charger). At the same time, we note that even a special rug can play the role of such a charger — in this case, the manipulator can, in fact, be constantly kept on charge. And even if you use a classic charger, the wireless format turns out to be much more convenient and practical than the wired one, since it does not require fiddling with cables and prevents wear and tear of the connectors from the constant connection and disconnection of plugs. However the speed of such charging is usually somewhat lower than that of a wired one — however, in this case it does not really matter (given the small capacity of batteries in modern mice). But the unequivocal disadvantage of models with this function can be called an increased cost. In addition, wireless chargers are usually not included in the kit, they must be purchased separately (although the reverse situation is also found with mats).

As for specific technologies, the Qi wireless standard is the most popular nowadays. This is a common format used by many brands. However, in addition to this, other technologies can be found in mice. A typical example is P...owerplay from Logitech: this charging format was developed specifically for branded gaming mice, the charger itself is usually made in the form of a rug, and a special removable module may be required for the mouse. In addition, Powerplay pads incorporate several technical solutions designed to increase the reliability of wireless communications and to minimize delays, interruptions and other problems with such a connection.

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.

The ability to adjust the weight of the mouse.

This feature is relevant primarily for gaming modelsused by professional gamers and advanced enthusiasts: for maximum accuracy of movements, it is necessary that the mouse has not only an optimal shape, but also weight. The change in weight is carried out by installing and removing special weights supplied in the kit. At the same time, in some models, by rearranging the weights in different slots, you can change not only the weight, but also the balance of the mouse, achieving the most accurate adjustment to personal preferences.
