The G903 Lightspeed (Check on Amazon.com) is the top-of-the-range gaming mouse from Logitech, and this says it all. It incorporates a series of improvements with respect to its predecessor [the G900 (Check on Amazon.com)] that include, among others, the wireless PowerPlay charging technology that allows us to use the mouse in wireless mode indefinitely.


Lightspeed is the technology this mouse uses to communicate with the wireless receiver. It uses the usual 2.4GHz frequency band, but according to Logitech, the G903 has a response time of just 1ms, providing the same responsiveness as any wired mouse.

The G903 also mounts what is considered the best optical sensor on the market, the PixArt PMW3366 which, in this case, provides a sensitivity of 200 to 12,000 DPI configurable in steps of 50 DPI. It also supports a maximum acceleration of up to 50G and a speed of 400 IPS (inches per second)!

And, in spite of being a wireless mouse, it is quite light since it hardly weighs 110 grams. It also features an ambidextrous design with interchangeable buttons on both sides that offer a near-perfect level of customization.

The mouse has a symmetrical shape and is perfect both for left and right-handed users. Where the palm rests it sports the Logitech G logo that lights up when the mouse is turned on. On the front, we find two generously sized buttons that flank the famous 4G wheel with Logitech’s infinite scroll button. Behind the scroll wheel, we have two more buttons that, by default, raise and lower the mouse’s sensitivity.

Out of the box the mouse is configured for right-handed users sporting two thumb buttons on the left and a plastic bezel on the right. However, we can easily switch these parts.

Underneath the G903, we find a generous sized Teflon area for smooth sliding. We also have the classic on/off switch, and a button that allows us to shift between profiles. There is even a compartment where we can insert an additional weight if we find that the mouse is too light.

Last but not least, on the front of the device we have the micro USB port for the charging cable or for use in wired mode.

Via the Logitech Gaming Software, we can configure the buttons and assign different profiles, as well as configure and assign various sensitivity levels. You will also be able to configure the response speed, but I really can’t think of why not just set it to maximum, in this case, 1000Hz (1ms response time).

We can also store specific profiles for every single app and game we use and enable them automatically every time we launch said app or game.

The RGB lighting customization, on the other hand, is very basic (there is no effect creator or anything similar) and limited to the palm logo and the three LEDs on the back.

Here we can also find information about the battery, including real-time energy consumption. With the battery charged at 100%, the Logitech G903 offers an estimated autonomy of 25 hours with the LEDs turned on and 36 hours with RGB lighting turned off.

We can even calibrate the optical sensor by analyzing the surface of the mat that we are using for optimal performance.

Logitech G903 Lightspeed – Performance

Logitech G903 Lightspeed – Performance

The performance of this G903 is impeccable, it offers great accuracy and precision and has a refresh rate of 1ms even in wireless mode (993Hz to be exact, no mouse reaches 1000Hz even in wired mode).

The Logitech G903 Lightspeed is slightly higher and longer than most gaming mice. I use a hybrid type of grip between claw and fingertip which is perfect for smaller devices but also comfortable with this G903.

The thing I miss a lot is the customary rubber inserts on the sides since they provide added comfort for my type of grip. Considering the price this is a flaw in my book but not a dealbreaker.

The thumb buttons are generously sized and perfectly positioned, on both sides. The scroll wheel is a bit rough and noisy, but this is quite common in new mice and is more than likely to soften up with use. The infinite scroll is a huge plus and something that only Logitech provides.

The PixArt sensor lives up to its name and the mouse behaves excellently in all areas, with a special mention for the configuration software that runs flawlessly and is very complete (although it will take you a while to configure everything to your liking).

Logitech G903 Lightspeed – Verdict

The Logitech G903 Lightspeed (Check on Amazon.com) delivers impeccable performance and is the most customizable gaming mouse ever made. Its wireless performance is among the best in the sector and has an autonomy greater than 24 hours (and if you splurge for the PowerPlay mat, it will be infinite).
