Over here, the Lightspeed G503 is up against some stiff competition. This is visible in the basic structure of both of them. It’s clear from the similar design pattern, with G903 costing a little less than the mighty G502.

Both have a freewheel in addition to the necessary notched wheel, which is an important factor in efficiency. In comparison to the medium-sized wheel found in G903, the look of a notched wheel in G502 is a little smarter. Furthermore, the thumb rest found in the G502 mate is not present in the G903 mate.

There is only a slight difference in weight between the two mice. G502 is the big brother over here, weighing in at 173g, which is quite a bit more than G903’s 166g. They’re both wireless and have rechargeable batteries.


The micro USB feature, on the other hand, appears to be quite intriguing in both cases due to the presence of that one specific port. When we look at the mechanical buttons on both of these mini burgers, we notice that G502 has a larger number of members in the form of specific buttons. The G502 has a total of 12 buttons, which is more than the G903’s 8 buttons.

However, with four side buttons, G903 tries to make an indelible impression on the minds of those who fight valiantly for its rule with the three buttons present in G502. However, G502 regains control of the game when we discover 21 distinct programmable inputs in it, compared to G502’s 15 programmable inputs. The presence of associated switches gives them both the profile and DPI (CPI) switching power.


The presence of distinct categories of their corresponding models enlivens the spirit of their distinctive Optical LED sensors. The latest Focus+ sensor is found in the Logitech G502, while the PixArtPMW3366 sensor in the Logitech G903 is impressive in terms of managing sensitivity based on their respective tonal properties.

The nature of the sensors has a significant impact on the CPI (DPI) rates that surround them. The rule appears to fall into G502’s hands due to the presence of a 20,000 CPI rate, which takes the lead over here, causing the other one to follow suit with a 16,000 CPI rate.

The champion G502 maintains its lead in wired latency, with a 10ms difference from the G903’s 8ms. Because the Logitech G Hub software is installed, they have full access to both Windows and macOS, making them ideal for gamers.


Because of the precision of its drivers, the G502 appears to be the winner here, and the extremely sensitive nature of the Focus+ makes the deal a valuable one at a premium ranged price.

The other member of the clan, on the other hand, is a silent observer who arranges himself according to the convenience of the clientele at a technically low price that is ten to fifteen dollars less than the leading monster.


With its flexible support system and features that appear upright and fantastic, the Logitech G502 Lightspeed Wireless is the hero who will save the gaming day for you. We also have the jumbo feature that was discovered within this work of technology art.

Its power lies in the sensor, which serves your best’s sensitive nature with its highly developed olfactory, or sensitive nature, in other words. If the high price is bothering you, you can seek refuge in the Logitech G903 Lightspeed, which offers similar features but in a less lavish pattern.
