Persons are nonetheless sceptical of connectivity points, battery life, and simply total efficiency. For a very long time, it’s been extensively thought of that wi-fi mice simply can’t stack as much as nice wired gaming mice, particularly for aggressive gaming.

The G603 may very well be the wi-fi selection for everybody

However the Logitech G603 could be a game-changer for wi-fi gaming mice. Logitech occurs to be one of many only a few corporations which have embraced wi-fi peripherals as the longer term.

However can the G603 overcome the problems which have plagued wi-fi gaming mice for the reason that starting? On paper, it positively has the potential to take action. Let’s see what makes it stand out from the gang.

The Unboxing Expertise

Entrance of the Field

Earlier than we get into the complete in-depth assessment, let’s have a fast take a look at the unboxing expertise. The Logitech G603 Lightspeed arrives in a modest and compact field. The field really matches the black and gray color scheme of the mouse itself. The general look is sort of minimal and smooth. The entrance of the field has an image of the mouse itself, together with the G603 printed in a big blue font.

The bottom of the field

The again of the field reveals off the important thing options of the mice. This consists of the brand new Hero Optical sensor, the Lightspeed wi-fi expertise, and the exceptionally lengthy 500 hours of battery life. It additionally has the power to modify between a number of units seamlessly. Sufficient concerning the field, let’s transfer on to what’s contained inside.

The mouse and all of the equipment are encased within the conventional plastic packaging, which is simple to open with out frustration. The field consists of the mouse itself, the wi-fi USB dongle, a USB extender cable, and two Duracell Alkaline AA batteries.

Field Contents

After pulling out the mouse itself and dealing with it for the primary time, my first impressions have been rock strong. Issues solely get higher from right here on out, so hold studying.

Design And Construct High quality

Minimal gray and black color scheme

The Logitech G603 Lightspeed has a straight-forward ergonomic design. The outer shell is principally the identical as Logitech’s personal G403 gaming mouse. It additionally appears to be like just like the G703 when it comes to form. This mouse has very clear traces throughout, that are a design component of the mouse. I’m fairly keen on the black and gray color scheme they’ve opted to go for. It actually offers the mouse a clear look to it.

Quite a lot of the brand new higher-end gaming mice are rocking some loopy designs, so the G603 is sort of a breath of contemporary air. It’s not flashy or in your face, nevertheless it nonetheless appears to be like pleasing total. The mouse has a matte end to it, however the high gray portion and the perimeters have a tender rubberized contact to them.

The Logitech G emblem is correct within the centre of the mouse. No backlighting is current right here, so in the event you completely want RGB in your setup, which may hassle you. I don’t care about that each one an excessive amount of, as I favor a subdued design any day of the week.

Logitech went again to the drafting board and determined to make use of an ergonomic design for the G603 wi-fi. Most of their new wi-fi mice make the most of this design, so in the event you’ve used a Logitech mouse earlier than it ought to really feel proper at residence. The mouse has a noticeable curve in the course of it, so palm grippers ought to really feel comfy right here. The gray accent additionally fades away to the black fairly properly on the perimeters, which retains that minimal aesthetic alive.

On the backside of the mouse, you’ll discover the Hero Optical sensor (extra on that later). To the left of that is the facility button, the place you may also toggle the excessive or low-performance (battery saving) modes. To the precise of the sensor is an enter choice button, the place you’ll be able to change between a Bluetooth connection or the wi-fi dongle.

The skates on the backside glide very easily

The construct high quality is definitely fairly strong total. It makes use of plastic supplies however doesn’t really feel low cost in any approach. The whole lot is put collectively fairly properly. If the aspect buttons and DPI buttons have been a bit extra strong, I’d say the construct high quality would have been good.

Button High quality and Scroll Wheel

The left aspect of the mouse consists of the 2 thumb buttons. They’ve a shiny end to them and are massive sufficient to achieve simply. They require a little bit of agency strain to activate and have a great clicky response. When pressed the give a crisp clicking sound from the within. They may have been a bit extra responsive, however I can’t complain an excessive amount of.

The left aspect of the mouse

Shifting on to the highest of the mouse, that is the place the primary buttons are positioned of their common positions. The left and proper buttons are literally indifferent from the primary physique itself, which supplies them extra journey. These are utilizing Omron switches, that are extremely satisfying as common. The clicks are sharp, responsive, and sound superb. There’s additionally a DPI button underneath the scroll wheel, with a small LED indicator simply beneath it. The DPI button can rattle at instances, which is a bit annoying.

Omron switches

The scroll wheel is definitely the foremost critique I’ve with this mouse. It’s not dangerous by any means, however for the worth, I’d anticipate it to be higher than what’s current right here. It’s absolutely coated with rubber and has ledges to grip the finger. There’s no free-scroll characteristic right here seen on different Logitech mice. It doesn’t really feel all that premium, and the sound isn’t satisfying both. Nonetheless, we are able to’t complain an excessive amount of as a result of value.

Ergonomics and Consolation

It’s tough to objectively say a mouse is comfy as a result of this issue is solely subjective in relation to gaming. What may swimsuit my hand dimension and grip won’t swimsuit yours correctly. With that mentioned, it’s necessary to remember that the form actually does matter when it comes all the way down to it. Fortunately, the G603 goes to really feel proper at residence for most individuals.

The form on this mouse has the standard ergonomic really feel to it and it’s fairly approachable for most individuals. The thumb aspect buttons are positioned properly. They don’t get in the way in which but are comparatively straightforward to achieve resulting from their angle and placement. The matte end feels extremely premium within the hand, and I by no means felt like I’d lose my grip utilizing this mouse.

The ergonomic form is a delight

With that mentioned, whereas it’s good for palm grip and claw grip customers, I wouldn’t advocate it to individuals who have a finger-tip grip. It is because the curvature within the center may get in your approach. That’s not Logitech’s fault, as this mouse isn’t actually designed with that grip in thoughts.

The G603 makes use of two Duracell AA Alkaline batteries for energy. These appear to overwhelm the mouse at first. With each of the batteries inserted, it weighs in at 135g. That’s actually fairly heavy however fortunately this mouse capabilities with one battery as properly. The highest a part of the mouse is connected magnetically to the physique, so you’ll be able to simply pull it aside by tucking in a fingernail. Thankfully, the magnets are fairly robust and I’m not apprehensive about them carrying out.

High cowl

Inside right here you’ll even discover a place to tuck the USB dongle, so that you don’t lose it whereas travelling. In case you take away one of many batteries, the mouse is definitely 112g, and it doesn’t really feel as unbalanced as you may suppose. You can too exchange the batteries with others.

Connectivity And Vary

Let’s discuss concerning the wi-fi vary first. Coming from somebody who has used many wi-fi mice prior to now, I can confidently say that the G603 wi-fi has a wonderful vary. Quite a lot of wi-fi mice can face latency and stability points resulting from poor vary. Typically you’ll should plug the dongle nearer to the mice to battle this annoyance. Fortunately, that’s not a problem right here. Nonetheless, in case your PC is a bit additional away out of your desk, you need to use the offered USB extender for higher vary.

Connectivity can also be clean right here. There isn’t any noticeable lag, and the mouse doesn’t undergo from connectivity points. The Lightspeed Wi-fi expertise delivers 1ms of enter lag, which is spectacular for a wi-fi mouse.

Switching between completely different units can also be fairly easy. Say you could have a PC linked to the mouse by way of the dongle, and a laptop computer linked by way of Bluetooth. Simply press the button on the backside to modify between modes, easy as that.

Sensor Efficiency

The sensor on this nice wi-fi mouse is Logitech’s new “Subsequent-Gen” HERO sensor. This optical sensor is rightfully referred to as “Subsequent-Gen” as a result of it makes unbelievable progress when it comes to wi-fi monitoring and energy effectivity. In relation to wi-fi efficiency, Logitech is leaps and bounds forward of the competitors right here.

Positive the Pixart sensors such because the ever-popular PMW3360 and PMW3366 are extremely correct, however they’re not energy environment friendly. This new Hero sensor is simply as correct and responsive as these, and it’s exceptionally nice in relation to saving battery life. It truly is the primary of its variety. It repeatedly adjusts frame-rate processing based mostly on the mouse velocity. This permits for higher optimization and minimizes energy consumption.

It’s additionally mind-numbingly quick. It may observe at velocity over 400 IPS (inches per second) throughout the DPI vary, which is 200-12,000 DPI. It’s impressively responsive, and it has zero acceleration and filtering. Even when I shortly transfer the mouse from one finish of my mousepad to the opposite, it doesn’t spin out in any respect.

All of that is because of the Lightspeed Wi-fi expertise seen on this mouse. It’s Logitech’s reply to points with latency, stability, and connectivity. At no level does this mouse really feel like its a wi-fi one. In reality, as a result of responsive sensor, it might probably really feel even quicker than some wired gaming mice on the market.

Want I say extra? That is the very best sensor and monitoring you’ll discover on a wi-fi mouse, no questions requested. It’s wonderful for each gaming and productiveness.

Efficiency – Gaming & Productiveness

All through my testing, the G603 exceeded expectations via and thru. Even after placing the mouse via its paces, my preliminary first impressions weren’t tainted in any approach. Efficiency is clearly fairly important for a gaming mouse, and this wi-fi weapon is a delight for each productiveness and gaming.


Logitech depends on the Hero Optical sensor right here, and there aren’t any gimmicks current right here. The quick and responsive sensor paired with Lightspeed Wi-fi expertise delivers distinctive monitoring for a wi-fi gaming mouse.

You’ll be able to change between two modes: Excessive-performance and Low-performance. You’ll be able to change these modes with the change on the again of the mouse. At high-performance mode, the mouse operates at a latency of 1ms, and a polling fee of 1000Hz whereas the latency goes as much as 8ms and polling fee goes all the way down to 125Hz in low-performance mode. Clearly, the low-performance mode will preserve battery life, however you’d need much less latency in aggressive matches.

In my use case, it was exhausting to differentiate between a wired mouse and the G603 wi-fi. Like I discussed earlier than, there are not any connection points, so the mouse feels actually clean and correct. Taking headshots in CSGO with a wi-fi mouse has by no means been simpler. There isn’t a jittering right here both. General it’s actually among the finest performances I’ve seen from a wi-fi mouse.


The G603 isn’t simply imply for gaming. In reality, due to the consolation and total ease of us, I discovered that this mouse was wonderful for productiveness. The dearth of a cable actually helps rather a lot in everyday use. I really feel extra comfy utilizing a mouse with out worrying concerning the cable. The acceleration right here is sort of minimal and doesn’t intervene in any approach. So dragging and dropping recordsdata, scrubbing via a video, and different miscellaneous stuff all feels very fluid.

Plus, with the software program, you’ll be able to set completely different profiles for each productiveness and gaming. This manner you received’t get annoyed in the event you’re the kind of one that retains altering the DPI velocity when switching between applications.

Battery Life

That is the important thing space the place the mouse actually shines. The key purpose why aggressive avid gamers don’t use wi-fi mice is battery life. It appears like you have already got sufficient merchandise that should be charged up every day, so including a mouse to that record is simply annoying. However what in the event you had a mouse that you just didn’t must cost and it may final for months? Sure, I mentioned months.

Logitech advertises 500 hours of battery life on this wi-fi gaming mouse. These are completely super numbers, which is already a great signal. With eight hours of use on daily basis, that roughly interprets to 2 months of utilization. That’s within the high-performance mode as properly. In case you change to the low-performance mode and simply use that every day, then Logitech says you’ll be able to stand up to 18 months of use.

The USB dongle will be tucked contained in the mouse.

Whereas it’s exhausting to present you an precise quantity, you’ll be able to overlook about changing the batteries for a few months. We’ve had a G603 for private utilization for some time now. We primarily used it for productiveness and gaming, switching between each of the aforementioned modes when wanted.

These are actually spectacular numbers that we haven’t seen earlier than on a wi-fi gaming mouse earlier than. It’s good to see that progress is being made on this division.

Software program

This wouldn’t be a assessment of an ideal gaming mouse if we didn’t point out the software program. Logitech G Hub is unquestionably a strong device the place you’ll be able to tweak even essentially the most minor particulars. It’s been up to date with a smooth and fashionable look whereas retaining the entire customization options. Let’s have a fast look.

The house tab will present the units you’re presently utilizing, together with the profile tab on the high. You’ll be able to change between completely different profiles from right here and even make your personal. You can too use G Hub to search out profiles created by customers for various video games.

The G603 doesn’t have any RGB or backlighting, so there’s clearly no customization there. There’s nonetheless a sensitivity menu. On this menu, you configure the polling or report fee and tune the DPI as common. There are DPI speeds on the left which you’ll be able to shortly change to. Nevertheless, if you wish to fine-tune every part, you need to use the slider to search out the precise velocity for you.

Aside from that, you need to use G hub to report macros, and set keybindings for any of the buttons. There’s a tonne extra you are able to do right here. You’ll be able to pair alphabets to a particular button for simple entry, pair just a few applications corresponding to OBS to begin streaming with the clicking of a button and even bind easy Home windows capabilities to a key.


Hopefully, after studying via this in-depth assessment you’ve made up your thoughts. The Logitech G603 is a superb wi-fi gaming mouse. The Hero Optical sensor is quick and correct. There aren’t any points with stability, connectivity, and even vary. However the greatest plus in my e-book is the battery life. The G603 is unquestionably considered one of a sort. The extraordinarily lengthy battery life will prevent a number of complications.

For the retail value of $70, that is a completely stellar wi-fi gaming mouse. Lately, you’ll find it for a bit cheaper in the event you go searching, so it’s an absolute steal. Positive there could be just a few higher choices on the market when it comes to the “good” scroll wheel. Contemplating the sensor efficiency, the long-lasting battery life, and simply total worth, we are able to simply advocate this mouse to anybody.
