Logitech G305: Pro Gaming freed from the wire thanks to the Hero sensor

Ergonomics

At a time when the designs and materials of mice are more and more worked, the G305 denotes a little with its shell entirely in grainy black plastic. If this material does not offer the comfort of a soft plastic (soft-touch type, for example) and rubbery inserts that are found more and more often on the edges, it has the merit of being very resistant and not to get dirty too quickly . Form and materials are in any case the same as for the Logitech Pro Gaming and G203 Prodigy. The only difference is that the G305 does without backlighting of the logo and light border, so as to avoid wasting energy, since it is a wireless mouse.

The small size of this G305 (116.6 x 62.2 x 38.2 mm) and its edges inclined inward always ensure a good grip and we do not feel too much the need for non-slip inserts. The plastic used nevertheless remains a little slippery, especially with sweaty hands, which can make rapid movements and lifting sometimes a little delicate, especially since this model is a little heavier than the wired versions. Indeed, the transition to a wireless link involves the use of an accumulator. Logitech has opted here for a simple AA / LR6 battery, which very simply takes place under the top cover. Such a battery weighing 23.2 g, this is not without consequence on the total mass of the mouse. However, Logitech managed to limit the weight gain of its G305 to only 13.5 g. A nice job to lighten the mouse itself therefore, allowing it not to exceed 100 g - unless storing the USB nano-receiver, which is only done in principle during transport. Our balance thus displays 98.5 g, battery included, which is very reasonable. Gliding does not suffer from this. The 5 PTFE pads suitably do their job and allow fairly fluid and silent movement.

The ambidextrous shape of the G305 is also appreciable, although we can only regret the absence of buttons on the right edge (only present on the left edge), which rather means this mouse for right-handers.

Anyway, users with small hands will be delighted with such a template. The compactness of the mouse nonetheless invites more to be taken with the fingertips or claw, allowing a certain nervousness. The comfort of handling is not bad so far, but in the same way as for a nomadic mouse, this is not the strong point of the G305. We are indeed in the presence of a mouse designed for the game and this is observed up to the buttons, independent of the shell and associated with reactive switches. The main buttons still take advantage of the tension mechanism, now widely used on Logitech G-series mice.

As on the G203, the main switches are signed Omron and guaranteed for 10 million activation. "Only", are we tempted to write, since those of Pro Gaming double this number, and more and more mice incorporate switches guaranteed on 50 million activations. Strategy game players and other Moba players may be aiming for a little more endurance, for safety.

On the side of the two slice buttons, the click is also of good quality, the buttons showing themselves to be quite bright under the thumb. The same goes for that of the thumbwheel, despite the use of a "tact switch" type switch, in principle less enduring. The last button is located above the wheel and is used by default to modify the sensitivity of the sensor on the fly. Like the other 5, its function can be changed in the mouse software (see box).

The wheel is convincing. We appreciate its well-marked notches, which do not affect the smoothness of the scrolling. On the other hand, it is necessary to make a cross on the side switches, but these would have weighed down the mouse and are less useful for the game.

According to Logitech, the autonomy of the G305 is 250 hours with a single AA battery, equivalent to about 9 months of moderate use. And in fact, despite a few weeks of testing, we have still not reached the critical 15% energy threshold, under which a low battery indicator is triggered. We would certainly have preferred a rechargeable battery in USB directly via the mouse, but this would undoubtedly be felt on the sale price. The autonomy with a simple battery being quite high, this does not bother us too much.

Precision

Logitech has developed a specific sensor for its wireless mice: the Hero (for "High Efficiency Rated Optical"), recently used in the Logitech G603 Lightspeed mouse. Announced as 10 times more efficient than other equivalent sensors, it is nonetheless swift and supports accelerations of up to 40 g as well as speeds of up to 10.16 m / s. Characteristics equivalent to those of the PMW3366 sensor signed PixArt which equips many mice, including Pro Gaming, G502, G900 ...

Unsurprisingly, the performances are there. We do not deplore any drop or sign of any acceleration that could affect accuracy. The mouse follows the most abrupt movements and thus proves to be perfectly adapted to the game in low sensitivity, its small size predestining it besides for such a use. However, players who appreciate high sensitivities do not have to worry, the sensitivity can be adjusted in steps of 50 dpi up to 12,000 dpi. A very high value which, let us remember, is not really exploitable at present. Indeed, at this maximum sensitivity, a movement of less than a centimeter is enough to cover the entire width of an Ultra HD screen; in other words, goodbye precision.

Optical sensor requires, surface recognition is a little more capricious than with a laser sensor and we must forget the glass desks or other shiny or too reflective surfaces if we want to do without mouse pads. Nevertheless, we observe a good behavior of the sensor on rather heterogeneous coverings and our wooden and slightly satin offices did not pose any problem to him. We recommend, however, a good mouse pad to ensure the best possible glide, optimal precision and preservation of the skates.

Regarding the wireless connection, same topo as for the G603 and other Logitech mice since the G900. The Swiss manufacturer masters his subject perfectly and the latency is almost as low with as with wireless. No particular energy saving here, it is always a question of an exchange frequency of 1000 Hz (1 ms) with the computer. Again, despite our attempts, no way to detect cuts or other weakness in wireless, it's as good as with a Logitech Pro Gaming. It would not be the same in Bluetooth, and that is why the mouse only works with its small radio receiver which is plugged into a USB port on the computer.

Conclusion

This wireless version of Logitech Pro Gaming incorporates all the qualities of its model, offering equivalent performance. A good choice to play wirelessly and without compromise with a mouse that remains fairly light and enjoys good autonomy.
