Comparison A4Tech XL-747H vs A4Tech XL-740K

The length of the cable that is equipped with a mouse with the possibility of a wired connection (see "Type of connection").

When choosing this parameter, you should first of all take into account the distance from the manipulator to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get tangled at hand and create inconvenience. As for specific values, the most modest wire length in modern mice is 1 m or less ; such devices are intended mainly for laptops. Most desktop manipulators come with cables that are 1.1-1.5m or 1.6-2m long, with some models running longer than 2m.

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.

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.

The presence in the mouse of its own built-in memory.

The main and, in fact, the only way to use such memory is to store various advanced settings (for example, the functions of programmable keys, or even entire user profiles for various games or other tasks). This feature is relevant mainly for gamers, so almost all models with this feature are gaming.
