Comparison Logitech G903 Lightspeed Wireless Hero vs Logitech G Pro Wireless

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 polling rate shows how often the mouse sensor communicates with the computer about cursor movement. The parameter is measured in hertz (Hz), and one second is taken as a unit of time when evaluating it. The smoothness and speed of cursor movement directly depends on the sensor polling frequency. Directly related to this is the mouse response time - this is the time period during which the signal about the movement of the manipulator will reach the display of a change in the cursor position on the screen. Response time is measured in milliseconds (ms). The more hertz the mouse has, the shorter the response time it demonstrates.

The number of buttons provided in the design of the mouse. However, the term "buttons" can also refer to specific hardware solutions — for example, a solid touch area used in many Apple mice counts as two buttons, because. it is divided into two working areas. But the clickable wheels, as well as the power button, are not taken into account in this calculation.

The minimum number of buttons for modern mice and other similar manipulators is two : this is the number that is necessary for comfortable work in most modern operating systems. If there are more than two keys, this means that there are additional buttons responsible for specific actions. So, even relatively inexpensive devices can be equipped with 3 – 4 buttons ; in addition to the 2 main buttons, they can have, for example, 2 side thumb keys, or 1 double/triple click button (see below). Solutions for 5 – 6 buttons are extremely popular nowadays; among them are many gaming mice, where the mentioned thumb buttons are supplemented with a double / triple click, a sniper button and/or a DPI switch (see also below about these functions). And in the most multifunctional models, 7 – 8 buttons and even more can be installed. In some cases, this number exceeds a dozen and a half; such mice are usually gaming devices designed for RPGs and other simil...ar genres where it is important to have a wide range of actions at your fingertips.

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").

A wheel with an accelerated scrolling mode that allows you to scroll through a large “sheet” of pages in text documents, spreadsheets or on Internet resources in just one movement. The inertial wheel is a hallmark of a number of Logitech mouse models.

- Teflon (PTFE). Polytetrafluoroethylene (PTFE) glides - also known as Teflon - are characterized by an extremely low coefficient of friction. As a result, mice with Teflon feet boast excellent glide and high cursor speed on any type of surface. The minimum level of friction allows you to easily control the movements of the mouse. Manipulators with Teflon gliders perform well in dynamic games and reduce wrist strain during prolonged work at the computer.

— Metal. When properly sanded, the metal feet provide excellent glide for the mouse, and they also have a long service life before abrasion. Note that manipulators with metal gliders are best used on plastic or other hard-wearing playing surfaces. Using a mouse without a mouse pad runs the risk of scratching the surface.

Grip — a way of holding in the hand — for which this model is best suited.

Grip types are divided according to the position of the hand on the mouse. This parameter is relevant primarily in games: for maximum efficiency, the player needs a mouse that matches the usual type of grip. This is especially important for professional eSports, where any little thing can be the key to victory or defeat. Therefore, the types of grip are indicated mainly for gaming mice (see "By Direction"). At the same time, one can come across statements that certain types of grip are best suited for certain genres of games, but this is not entirely true: the main selection criterion is the user's personal preferences and characteristics. For example, some players quite successfully use a "slow" palm grip in dynamic shooters, compensating for the reduced speed with a good reaction; and others, even in quests, prefer a "quick" claw or finger hold.

Here is a more detailed description of the most popular grip options:

— Palmar. A holding method in which the mice touch both the entire fingers and most of the palm. In other words, with such a grip, the palm with fingers rests on the mouse, making maximum contact with it. It is under this option that most of the "rodents" are initially made, it is also popular in gaming models. Most models, specialized specifically for the palm grip, have a large length, as well as a characteristic asymmetrical design with protrusions...and depressions on the body — for maximum ergonomics; although there are exceptions. Anyway, the main advantages of this method of holding the mouse are the minimum strain on the wrist, as well as good smoothness and accuracy of movements. On the other hand, the speed of moving the mouse may be somewhat slower than with other types of grip.

— Claw. A claw grip is a grip in which the user's hand forms an arc and touches the mouse only with the lower part of the palm and fingertips. At the same time, the classic claw grip assumes an almost perpendicular arrangement of the fingertips relative to the buttons, but this requirement is not strictly necessary — the fingers can also lie at a slight angle. Anyway, due to the reduction of the contact area and the greater degree of freedom for the hand, such a hold provides more speed than the palm hold, and at the same time it is easier to master than the finger hold. Therefore, many gamers consider the claw grip to be the best option for shooters, action games and real-time strategies where reaction speed is important. Specialized mice for this method of holding are usually somewhat shorter than traditional "palm mice", and they often have a characteristic "hump" in the back of the case.

— Finger. A grip where the user only touches the mouse with their fingertips, with no hand contact with the mouse (but the wrist remains stationary). This type of grip allows you to achieve a high reaction rate, but it is quite difficult to master and does not differ in accuracy, especially if you are not used to it. However, many users use this method of retention intuitively, without thinking; the finger grip is specially mastered mainly by professional players and enthusiastic enthusiasts. Mice of this format usually have a small weight with a centre of gravity shifted closer to the front, and the body is made relatively short, most often symmetrical, and the “hump” (protrusion) is located closer to the centre of the body, or even absent (based on the fact that the palm still does not touch the mouse).

Note that there are models that combine several grip options — up to all three at once. The design of such mice may provide adjustment for one or another method of retention, however, the presence of such an adjustment does not interfere with clarifying separately.

Additional features of the cable that the mouse is equipped with.

These features may include a winding system, a detachable wire, and a braided wire(however, most modern mice still have a cable without a braid). Here is a more detailed description of all these features.

— Retractable. Wire equipped with a special coil for winding. This feature greatly simplifies transportation: during off-hours, the wire is as compact as possible and does not get tangled, and when used, it can be unwound to the desired length (usually the coil allows this possibility). All this is especially important for laptop mice (see "In direction") — in fact, most models with a wire reel fall into this category.

— Removable. Wire that can be detached from the mouse. Almost all mice with two connection options have this feature — wired and wireless: when working in a wireless format, the cable can be removed so that it does not interfere. However, there are also purely wired devices with such a cable — mostly laptop devices, where the wire is removed for ease of transportation. Also note that most often a universal connector like microUSB is used to connect the cable, so if necessary, the wire can be replaced with another one — for example, a longer one.

— In a braid. The presence of an additional braid on the mouse cable. This feature makes the wire more d...urable, reliable and resistant to bending. On the other hand, braid tends to accumulate dirt and fray when worn; because of this, the wire sheath loses its presentation faster than in mice without a braid. Yes, and such a wire is more expensive than a regular smooth one.

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.
