Logitech G903 Wireless Gaming Mouse Review

Hot on the heel of its release of Logitech G900 wireless gaming mouse in 2016, this year company launched G903, which is nearly identical revised version just to support its new POWERPLAY mouse mat that will charge your mouse while you play and you don’t even need to plug or dock it in, or swap your mouse batteries. And it is yet best wireless gaming mouse out there.

Equipped with the most precise optical sensor, Logitech G903 offers the professional gaming experience within budget. It has both corded and wireless feature, adjustable weights and the custom grip option which basically let you adjust the mouse design as per your preferred grip style.

Design, Grip And Ergonomics

With charcoal black colored it has slick futuristic appearance with fins and cutaways which recall modern Lamborghini or perhaps FORD GT. Luckily, not a single flash gets in the way of comfortable grip.

Its mid-profile design is fine for both palm grip and claw grip users. However users with larger hands are more comfortable with claw grip. Nothing was found uncomfortable holding this mouse.

Mouse Buttons

Left handed users or those who just prefer using both sides, will definitely appreciate Logitech’s customizable side buttons. You will find spaces for 2 buttons on both right and left hand side of mouse. Default configuration include 2 buttons on left and a flat cover on right in right-handed configuration. However you can pop off the snap and cover in buttons to replace left-side buttons with cover, and mouse will become for left hand users. Otherwise, if you just love buttons, snap in all 4 side buttons. Mouse software completely supports left, right and both-side configurations. Indeed, if you see you do not like thumb buttons, take them off completely. There is also an option for that in the software.

At the top of mouse there are 2 small buttons to adjust DPI settings. Scrolling wheel is equipped for left, right and down click and has pleasing knurled rubbery feel. There is a button on the top that switches scrolling wheel from firm style with obvious detents to freely scrolling mode which acts just like flywheel. That isn’t useful in many games, however it is surprisingly pleasant for desktop activities such as scrolling long web pages or scrubbing by video editors.

At the bottom there is a switch that turn wireless receiver on/off, a button that toggle through on-board stored profiles that you can have up to five, and a coin shape disc which is a blank cover to snap on POWERCORE module if you use this mouse on POWERPLAY mouse pad, or you can also add on small 10g weight if you do not.

Cable and Micro USB Port

There is a micro USB port in the front for charging. There is a cable which has a funny looking connector and it is very simple to plug in because it lock in safely that it will never fallout during gaming sessions. At the time when mouse is not plugged in, you can plug wireless receiver in cable with little USB dongle extension.


At just 110 g, Logitech G903 is quite light, however I did not feel like 10 gram made all that difference. Yet, if you are particularly sensitive about it, it is nice to add a little more heft.

RGB Glow Light

No doubt, no high-end wireless gaming mouse is complete without glowing RGB light. Logitech has covered there also. Its G logo on back of 3 small battery levels light in center light up, and it can be set to any type of color you select, or made to cycle or pulse through colors. Most games can control LEDs with Overwolf, which is an additional 3rd party software which integrates with mouse software to work with G-series gaming products. And no doubt, if you need multiple light-up all Logitech G series, you can set it to sync.


All Logitech’s gaming accessories including keyboards, mice, webcams and headsets are controlled by single software app. When you have several Logitech peripherals, it is fine to have all in one place. It is relatively fast and compact, therefore it would not suck away your memory or CPU resources.

Logitech provide plenty of control over G903 functionalities. You can select on board memory, store up to 5 profiles to assign buttons and macros, lighting, sensitivity as well as you can use PC based solution which stores profiles that can change mouse settings automatically as soon as you launch any game. You can switch between 2 modes any time.

While setting buttons configuration, one can re-map each and every function beside up and down scroll wheel and left/right buttons. One can swap those for left hand operations, however you cannot change their functions. There are 4 buttons layout, no buttons, 2 button on left, 2 buttons on right and buttons on left and right. It is great to see an ambidextrous mouse which gives you option of using buttons on opposite sides from thumb or not.

Side buttons, DPI adjustment buttons and mouse wheel clicks can each be set to 1 of 22 different functions of the mouse or any key combo or keystroke or any detailed macro programmable.

One can also set up 5 DPI sensitivity levels from 200 – 12000. This is amazing ability to adjust different DPIs and store in a mouse. Most user prefer only 2 levels, fast movement and other for precise aiming.

Software allow you to tune mouse movements to different surfaces and there is a marked difference between accuracy and sensitivity while using presets for hard and soft surface, therefore you will want to pick right setting for preferred mouse mat.

Logitech’s software syncs with your phone also. For this you need to use Arx control. Grap this app for Android or iPhone, sync with your computer and then adjust mouse functions and monitor PC stats like RAM usage, CPU utilizations and the like from your phone.


Gaming mouse performance starts with sensor. Pixart PMW 3366 used in Logitech G903 is favorite among enthusiast gaming community. It always tracked perfectly, picked up slightest movement without any interpolation or smoothing. To snap turn in Unknown Player Battlegrounds it does with quick flick, mouse tracked right as you move, matching the acceleration accurately and stopping accurately when stop. Clicking on smaller precise interface in games such as RimWorld and Civilization felt easy and natural.


Switches used in Mouse Buttons

There are mechanical pivot hinges used for left/right buttons. The push down on Omron switches feel great and have right button travel and fast returning rate, with satisfying click and no need of much tension. Switches used are just like those used in Logitech G900, however they are now rated for 50 millions clicks lifespan rather than 20 million.

Battery Life

Highly depending on the configuration you use, battery life ranges from around 22-32 hours. Turning LEDs off give you more and you can also shed off some milliamps by reducing polling rate from 1,000 Hz. Which only provide you another hour. Software’s battery tab include nifty display that accurately estimates amount of power used by current settings and amount of time a full charge can last. Therefore you can use the mouse for 10 to 12 hours for 2 days without charging it. Notification is send in Windows and flashing level lights on mouse alarm you for low battery, however after this you have ample of time to finish your gaming sessions before charging it.

The only downside of Logitech G903 is that to charge it, you need to plug it. You don’t have any handy dock for plopping it on. There isn’t any removable batteries swapping option. However it doesn’t take more than 2 hours to charge completely and you only need it to charge after every 2 days.

Wireless Technology and Latency

It uses same wireless technology as used in Logitech G900. Logitech now has branded LIGHTSPEED. Logitech’s optimization extend beyond simply polling rate at 1000HZ and minimize each and every source of latency from mouse electronics to wireless radios. Logitech includes mountains of testing data and charts to prove motion latency, click latency as well as movement accuracy and are found to be as good as other best wired mouse.


The Logitech G903 and Logitech G703 are first Logitech models that support this new POWERPLAY system. Powerplay is just a mouse mat which integrates the wireless receiver and wireless charging. Just plug your mouse cable in the mouse pad, snap small coin like POWERCORE module at the bottom of mouse. When you forget to charge your mouse, now you can have a wireless mouse which never need to be plugged in, put on stand or to swap out batteries for.

Its surface is finely sized, around 13.5 x 11 inches, which is big enough for serious movements. It includes 2 surfaces to put on top, soft and hard to select. Logitech doesn’t officially support the other mouse surfaces, however other mouse surface can work fine without upsetting wireless charging, until it is pretty thin and with no metallic substance inside it. You just need to ensure that it roughly matches dimensions of base.

Charging with POWERPLAY is slightly weird. While use of mouse, no change in charge was found even when used for 2 hours charge hovered at 60 percent exactly, never falling or climbing. During gaming, pad charges fast enough in order to supply as much power used by mouse. However leave mouse in middle of pad and went away for couple of hours, and it charge it up, albeit yet pretty slowly. Thus charging mouse directly into cable is only way to charge it up at reasonable rate.

However does it really matter? Whole point is to use wireless mouse like wired mouse, walk away without thinking of batteries, and POWERPLAY system achieves that. Therefore no matter it takes 2 days for charging up using pad, charging never fall, so you are effectively on unlimited wireless mode.
