Logitech – G903 LIGHTSPEED Wireless Optical Gaming Mouse with RGB Lighting – Black

There are basically two schools of thought when it comes to gaming mice. One favors stripped down minimalism focusing on low weight and simple designs that are likely to pass muster at an e-sports tournament. The other, which is the one I prefer, is that one should stick a button on every possible surface of the mouse that makes sense, then add two more for good measure.
The G903 might be the first mouse I’ve used that actually caters to both of those positions at the same time. And if that isn’t enough to get your attention, the rest of the features absolutely will.
First up, I’d like to talk about build quality. This is an astonishingly sturdy mouse given the fact that they’ve gone to extraordinary lengths to make it weigh about as much as a pair of tissues and half the buttons are only being held on by tiny magnets. The case is a sturdy plastic with a light non-rubberized finish, and potential weak spots (such as the the point where the main buttons join the rest of the body) have been reinforced with exposed gussets to provide strength without adding weight. The buttons themselves are mechanical and feature metal springs to provide an appropriate level of tension, giving it a very pleasant feel that’s substantially more “solid” than what you get from even other high end mice. The scroll wheel is primarily metal with a standard rubber tread strip in the middle. They’ve even reinforced the micro-USB charging/data cable to pretty much rule out the possibility of you ruining the port on the mouse by typical rough handling. I foresee no problems tossing this in your bag and bringing it with you on the road. They even included a rigid carrying case for the small accessories you’re more likely to lose, like the removable button covers.
Speaking of, the customization options you get with this mouse is another major selling point. The mouse has an ambidextrous design, with a total of 4 removable thumb buttons (2 on each side.) Everything’s held on by magnets, making it very easy to swap out the buttons based on what you need. Since I’m of the opinion that you can always use more buttons I immediately replaced the button cover on the right hand side with two more buttons to give myself some pinkie switches. It was a little awkward at first, given that the mouse tapers a little sharply at the front and my hands are on the larger side, but once I’d trained myself to stop hitting them by accident and set them up as copy/paste buttons via Logitech’s G-Hub application I was quite pleased by them. This program also lets you fine-tune the lighting effects and the Hero sensor, which by default will top out at a very twitchy 6,400 DPI rather than its full 16,000. This is, in my opinion, a good thing. At full sensitivity even the tiniest mouse movement will send the cursor across a standard 1080p display. Also worth pointing out is that unlike a lot of wireless gaming mice, all these customization options can be set over a wireless connection rather than requiring you to plug it into your USB port for the more advanced programming. There’s also an included 10g weight you can install in the back of the mouse if you prefer something just a little heavier, in the same socket that allows you to install the powerplay wireless charging puck that lets you charge the mouse off of a powerplay enabled mouse pad while you use it. Pretty much the only thing you can’t add on here is a thumb or finger rest.
Finally, i want to talk about what it’s like using the mouse for tasks that aren’t gaming (since for most people that will sadly represent the bulk of what it gets used for.) And I have to say it’s pretty good for that too. The wireless connection is rock solid, and is indeed so close to wired performance that you’re unlikely to notice the difference. They’ve included one of Logitech’s excellent hybrid scroll wheels that can switch between ratcheting and smooth action (and if you’ve never tried one of these before, trust me, they’re amazing) and it’s very easy to change the DPI to something more conducive to productivity without needing to go into the app. The only real concession they’ve made is that unlike most Logitech mice that use the hybrid scroll wheel design, the switch between the ratchet and smooth modes has to be done manually rather than automatically in what I’m pretty sure was done to keep weight down. And I did find myself missing a thumb rest, and I’ve gotten very used to canted mice that are a bit easier on your wrist, so it’s probably not what I’d recommend for someone who’s looking exclusively for a productivity device unless you’re working in a field such as design work where you really need the high quality sensor and adjustable DPI. But it’s certainly a better experience than most devices out there, and is definitely one of the only mice of this quality that can be easily and seamlessly adapted for left hand use.

Logitech G903 Lightspeed is not only an outperforming gaming mouse, but this is perhaps the best mouse let alone gaming mouse my hands have ever graced. The design, weight, and feel just leaves your hands feeling comfortable no matter what task you are doing. Highest levels of DPI I also ever expected with 16000 that just will own in gaming on first-person shooters. With so many good gaming mice out there G903 stands out as the better one even if its one of most expensive mouse you buy.
Design: First off I want to talk about the design of the mouse because it’s really actually amazing. It doesn’t matter if you are right-handed or left-handed the G903 is ambidextrous leaving an extremely comfortable feeling no matter in which hand you use. There are 11 buttons (Yes! 11 buttons.) on this mouse, Every button is programmable but more on that later. The scroll wheel can be suited for gaming and surfing the web. When using there is no awkward slip off from my palm as the mouse is a full-sized mouse. One thing that gets me with this mouse is that each click or button press its more a more satisfying click, it just feels so good to use. Whatever engineering went into the G903 it paid off big time.
The coating on the mouse does feel premium all the way around. Design is definitely speaking “gamer” like so if you don’t like the look of gaming products this might not be your cup of tea, Though to me the black mouse with the smooth transitions of the LEDs looks so beautiful just sitting on the desk. Just speaking, in general, the Logitech G903 every part just feels is really well made. The 10G Removeable weight for me adds the perfect amount of heft to the mouse allowing me and my hand to play for hours on this thing. Logitech presentation feels great when it comes to this mouse.
Battery life is the top of its class! 140 hours with LEDs off and 120 hours with the LEDs on. Corsair’s own Dark Core RGB is nice on its own but with the battery life fails to hold up. As for G903, the battery life lasts 120 hours way more than Corsair Dark Core ever could, This mouse keeps going and going and doesn’t take long to charge up at all. DPI Levels reach to 16K which speed blaze from side to side on ultra-wide monitors, The real shine of this mouse here is playing E-sports titles on a 240hz monitor. Every movement is precise when it comes to gaming online, every moment is crucial. So using this on PUBG and Rainbow Six: Siege G903 can keep up as fast as my eyes allow me to. Haven’t tried Fortnight but I’m sure this mouse works perfectly for snappy responses.
A top defining feature of the Logitech G903 is that you can is a “POWERPLAY” mouse pad that can charge up the mouse as you use it wirelessly. It is sold separately and I haven’t had a chance to test it but I will be one of the people who buy it for my gaming rig in the future. I truly do enjoy the mouse and I’m a sucker for LEDs I have to admit so this is one of the best feeling mice I’ve used so I want to keep it up.
When it comes to software the G-Hub is great, giving an almost unlimited amount of customization when it comes to tailoring the mouse to your needs. There are 11 buttons that can be programmed to do anything you want and you can add your own programs into the software for the mouse. Here you can also adjust the DPI, Change the LEDs, Brightness of the LEDs, and a whole lot more. There is even a 32 bit ARM chip in the mouse and you can save profiles from PC to PC which is super useful. Even for me as a PC gamer feel like this is overkill and overwhelming but everything works flawlessly.
At the end of the day, this to me is one of the best mice I’ve used to date. One I can see myself using for a very long time. With this many features, there isn’t anything missing from Logitech G903. The only thing I can see be an issue is price but every single thing it can do is totally worth it. G Team made an excellent product for gamers, One that actually worked perfectly as advertised…One that I actually enjoy using every day when I game on PC. I can’t wait to try this with the “Powerplay” pad. Logitech made a well above exceptional mouse. 5 out of 5 stars.

Design
The Logitech G903 wireless mouse is the same design that has been around since 2017. The style is somewhat angular and aggressive looking but, not so much so that it would garner strange looks outside gaming circles like some. The has a styled G, for gaming, that lights up and some lights that indicate the dpi setting as well as serve as additional lighting. The design is ambidextrous with identical shoulder buttons on each side that can either be covered with plastic covers that magnetically snap on or configured as additional buttons for a total of four shoulder buttons. In the center are two buttons to increase or decrease the dpi mode to increase or decrease the sensitivity. A button immediately behind the scroll wheel allows you to change the scroll wheel mode from smooth scrolling to stepped scrolling depending on what you are doing. Underneath is a compartment held in place with magnets where you can place a 10-gram weight if you prefer a heavier mouse. A total of six Teflon pads steady the mouse and help it glide across the surface. Included is a braided cord, USB adapter, and USB nano receiver. The mouse can operate hardwired or you can even use the cord along with the USB adapter to move the USB nano receiver to a place with better reception if, say for instance, your USB plugs are located on the back of your tower. It’s a nice touch to have this function so that wireless operation has the best chances of being interference free.
With wireless mice, one concern is running out of battery mid game. Of course, you can solve this by going hardwired but if you have some extra money you can splurge for Logitech PowerPlay mat. It allows the you to keep the mouse battery from draining during gameplay as it continuously provides power wirelessly. In independent tests it does not increase the battery level during gameplay but keeps it steady, so your battery won’t die. After gameplay stops, the pad can further charge up the mouse while not in use.
Setup
Like pretty much any Logitech device, setup is pretty much painless out of the box. Plug in the nano receiver or cord and Windows does the rest. It gets you up and running quickly. If you want the advance lighting features a small amount of manual work is required to install the Logitech G HUB software. HUB allows you to configure custom lighting profiles, include other compatible Logitech devices besides the mouse. You can set lighting, dpi, button assignments, and macro settings as persistent throughout the system or game specific where HUB will automatically switch settings based on the configuration of the game. It seems like a small touch but it’s nice to be able to go from one game to another and have your mouse automatically switch everything about its personality without you needing to do anything after the initial setup. If you create a profile, then you can save and share your custom profiles with others. Although game configurations are still limited at this point, you can also look at and download game profiles from other gamers to see if you like their button mapping and lighting profiles.
Usage
The buttons and scroll wheel have the familiar Logitech feel if you have felt it before. Even though the design is ambidextrous, it feels more like a contoured mouse. Although common today, the customizable dpi settings really come in handy for daily use so that you aren’t flying across the page while browsing the web, but you can also get the quick response needing during gaming. You can adjust the rate on the fly, but button placement might make quick changes awkward. Your lighting effects will also make what mode you’re in a bit confusing. When in Windows, dpi changes provide a toast message saying what rate you are at but, in gameplay you must rely on the status lights on the mouse. A small issue is that the same lights that show what dpi level you are at are also part of the main lighting. This means dpi changes will for a very moment indicate dpi mode but if a lighting effect is occurring you might miss what mode you set it to. If this is really a problem really depends on your style of gaming. If you are the type that just switches and feels out the speed this won’t affect you in the slightest, but for those who are looking for a specific setting this might slow you down a bit. DPI modes go all the way down to a snail’s pace of 200 dpi up to a superhuman 12,000 dpi.
During usage both wired and wireless the lag, if any, was imperceptible. Button clicks happened what felt like instantaneously and with a satisfying click. The sensor tracked motion reliably and accurately against several surfaces with no hint of jitter. For gameplay the step motion of the scroll wheel would likely be the favored method as it provides a soft click as you scroll allowing precision weapon chances. If there were any criticism to lodge against use it would be that smooth scrolling often tends to scroll the opposite directly slightly each time your life your finger off the wheel. Also, the shoulder buttons are slightly high and back compared to the left and right mouse buttons. If you tend to like to hold the mouse more forward, you might find the reach to the rear shoulder button a bit of a stretch. If you prefer to hold form the midpoint back, then the shoulder buttons have been placed very well. Battery life has been very good at an average 1% drop per day with moderate usage including a mix of gaming and casual usage at 3 hours per day. Gaming battery life would likely be lower due to the higher dpi and constant usage, but you should still expect even a long gaming session won’t find you running out of battery.
Conclusion
The Logitech G903 looks and feels solid and has the Logitech feel that anyone has used before will immediately recognize. They work great at the beginning, but their micro switches tend to wear and act inconsistently as they age. Previous iterations of the G903 exhibited an issue with double and triple clicks with age so, hopefully Logitech has improved the hardware that caused the issue. Unless you are a heavy user, this might not happen until well into the life of the mouse at which point you are in the market for the latest and greatest anyway. Of course, if you are a Logitech fan you have likely experienced the micro switch problem at least once but the mix of features, consistency, and accuracy during the life brings you back. In the case of the G903, the overall operation and gameplay makes it hard to beat and deserves consideration if you are in the market for a gaming mouse.
