Logitech G303 Deadalus Apex Mouse Review

May 22nd, 2015 James Leave a comment Go to comments



We’ve seen a lot of Logitech mice over the years and to be fair most of them are really pretty darn good. We’ve even seen the mouse I’m about to review before, when pcG Gary took a look at the Logitech G302 Daedalus Prime. The mouse I have here’s not a G302 but a Logitech G303 Daedalus Apex, so what’s the difference? Well to be honest nothing other than the fact that the Apex uses a higher resolution optical sensor (PMW3366), supporting up to 12,000 DPI. Other than that the mice are identical! The G303 Deadalus Apex is still a right handed mouse with six programmable buttons and 16.8 million colour illumination.

The kind folks over at Logitech have also sent us one of their G240 Cloth Gaming Mouse Pad’s to take a look at, so we will be using this in testing as well as one of our regular mouse mat.


Logitech Gaming Logo ‘At the core of G303 is our best optical sensor, the PMW3366. Built with Delta Zero™ technology, it delivers exceptional tracking while minimizing speed-related accuracy variance, commonly known as “mouse acceleration”, allowing for quicker reactions and more consistent targeting. For maximum responsiveness, the PMW3366 sensor has zero smoothing or filtering across the entire DPI range—even at high sensitivity.’

The Logitech G303 Daedalus Apex came to pcG in a small blue box, as is the Logitech way. On the front there’s a large image of the G303 along with the Logitech name and the product name. There’s no lift up lid, so unfortunately there’s no looking inside…

On the back of the box, there’s really very little to see, in the lower left there is a small image of the G303 sporting a skeletal look allowing us to see inside. Other than that we have a set of specifications and features listed in various languages (see Specification/Features below). To be honest the mouse mat’s box is more interesting… 😉

Opening the top of the box allows us a sneak peek at the Logitech G303 Daedalus Apex and its packaging. The mouse and its contents may be well packaged and protected, but it’s certainly nothing to write home about. There’s no premium product feel here, despite the somewhat premium price!

There’s not much in the box either, other than the mouse we find just a couple of documents; one Safety, Compliance and Warranty guide and a basic user guide, that’s it folks! I must say at this point I’m feeling a little disappointed… 🙁

At the time of writing the Logitech G303 Daedalus Apex is retailing on Amazon for approximately £50 and comes with a 2 year warranty.

First Impressions


Logitech G303 Deadalus Apex and G240 Logitech G303 Deadalus Apex - 2 Logitech G303 Deadalus Apex - 1


After the somewhat boring un-boxing, I have to say that the theme continued as first impressions of the Logitech G303 Daedalus Apex are a little, well, meh! If you were to a look at it on face value; it looks like an odd shaped mouse!? That’s because that’s the only real impression it gives and the shape is indeed odd! There’s no extra buttons, no weights, no DPI indicator, there’s really not too much to get excited about. What we have here then (and I hope!) is one of those Pure Gaming mice, designed for a single purpose; to work and work well! We shall see…

Logitech G303 Deadalus Apex - left Logitech G303 Deadalus Apex - right


Looking at the Logitech G303 Daedalus Apex from the left side we see the two thumb buttons, that (for me) are not as well placed as they could be as they’re a little too far forward. At the back of the G303 we can see the honeycomb area that facilitates the 16.8 million colour illumination. The right hand side of the mouse is the same as the left but without the buttons.


Logitech G303 Deadalus Apex - front Logitech G303 Deadalus Apex - back


Looking at the front of the G303 Daedalus Apex we the attached 1.8m braided cable, one of the nicest braided cables I have ever seen. It looks great, it’s shiny and slippery and it’s also nice a flexible, despite its relative thickness.

Looking at the back of the mouse we can begin to appreciate its rather odd shape, as it’s the back where the oddity is most obvious. There’s very little support here and the back of the mouse pushes naturally into the back of the hand, it’s strange but it seems to suit my bastardized Claw/Palm grip surprisingly well!?

Taking a look from above we can see the centrally mounted scroll wheel flanked by the usual Left/Right buttons. Thankfully Logitech have chosen not to mess with this one (remember that Hyper Fast Scroll Wheel!), the scroll wheel is just a simple rubberised affair with well defined graduations. Behind the scroll wheel is the DPI switch (by default, but can be programmed) allowing you to switch between any of the five user-defined DPI settings. The main body of the mouse is covered with a nice soft touch surface treatment, that’s actually surprisingly grippy (soz bad word!), and the overall build quality is very good, as one has come to expect from Logitech.

Looking at the underside of the G303 we can see Logitech’s 12,000 DPI optical sensor (PMW3366) bang slap in the centre of the mouse. An Advanced gaming sensor with exclusive Delta Zero technology (what ever that is!?), the sensor is touted (by Logitech) as the most accurate on the market. The mouse features six glides (which is a lot); two at the front/back, two at the sides left/right and a further two (small ones) surround the sensor.

Overall there’s nothing here to complain about, but equally there doesn’t seem too much to get excited about either. Purposeful, I guess that’s the word for it…


Hardware Installation

Logitech G303 Deadalus Apex - connection The Logitech G303 Daedalus Apex simply connects by way of its USB plug found at the end of the 1.8m braided cable. From that point it’s just simple Plug ‘n Play!


Testing Methodology/Setup


The Logitech G303 Daedalus Apex mouse was tested using our Test Rig, a fresh installation of Windows 7 64Bit (service pack 1) was installed along with all appropriate Drivers. No software is supplied with the G303 but is required for full functionality. The Logitech Gaming Software software can be downloaded (here) and version 8.58.183 was installed and used throughout testing.


The following games were used during testing:


Hardware Performance


As I have already mentioned in numerous mouse reviews the £50 segment for PC Gaming mice is probably the most crowded, it seems to be the defacto price that Gamers are willing to pay; beyond this the mouse is getting expensive. So what does the Logitech G303 Daedalus Apex bring to the market for its £50 and how does the most accurate sensor on the market perform?

Well the good news is that the Logitech (PMW3366) Optical sensor performed flawlessly in testing. Although I have to admit there was no Gaming done at 12,000 DPI as I used my usual setup of around 1400 ~ 1800 DPI while testing. I had no issues in-game and tracking was always spot on from simple slow paced Games such as The Vanishing of Ethan Carter to fast paced Games like Battlefield 4. The G303 is one of those mice that after a while just feels like an extension of the brain, you almost forget the mouse is in your hand and you just concentrate on the job in hand. Movements and shots just need to be thought about, the G303 does the rest! As you can tell I’m impressed by the G303’s tracking and I am, really impressed. Logitech put a lot of work into this new sensor and it shows, good work guys.

So what about the comfort? Well at first I have to admit I was neither a fan of the look or the feel of the G303, but over time I discovered that the mouse ergonomics actually seemed to favour my bastardized Claw/Palm grip. This is a mouse for all of the Claw grippers out there and even the Fingertip Twitch Gamers too!

The rest of the mouse though is a little bit of a let down as there’s no additional buttons and even worse no DPI indicator, quite why Logitech keep forgetting to add this to their Gaming mice is beyond me!? I did find a workaround for this; by setting up three different Profiles with different DPIs that also had an associated illumination (Blue 1400, Green 1600 & Red 1800)! Also those thumb buttons are too far forward for my liking. Luckily the 16.8 million colour illumination comes to the rescue giving the G303 that little bit of missing bling!

Then there’s the G240 Cloth Gaming Mouse Pad, this seems to be the perfect partner for the G303 as once calibrated (there’s a special setting in the software for the G240) tracking seemed to be further enhanced. Although using this mat I found that I wanted to keep the DPI to 1600 or below, I even used 1400 for a while and it was spot on! Luckily my other surface (Aorus Thunder P3 Gaming Mouse Pad – Black) also worked really well with the G303 Daedalus Apex, helped by the fact that any mouse mat can be calibrated through Logitech Gaming Software.



    Of course we have seen Logitech’s Gaming Software before, but maybe you haven’t so let’s go through it together. Version 8.58.183 was used throughout testing and it can be downloaded here. The software is generic meaning that the same software is used for pretty much all of Logitech’s G Series peripherals, which is kind of neat.


    Logitech G303 - Gaming Software (Home) Logitech G303 - Gaming Software (Programming) Logitech G303 - Gaming Software (Macro)


    The main Home screen allows you to select which Logitech peripheral you wish to modify (bottom left). Here you can also choose to either manipulate the software on your PC (Automatic Game Detection) or the Profiles stored on the mouse (On-Board Memory). Choosing one or the other changes the selection icons in the bottom right of the screen slightly.

    The Customize on-board profile screen allows you to do just that. Here you can program any of the six buttons, either binding to a key, Windows function or a Macro. To the right of this you can adjust any of the five DPI settings from 200 ~ 12,000 DPI as well as control how many DPI settings will be supported. In addition to this you can enable up to three on-board Profiles and also control the Polling Speed (during testing it was left at the default 1000MHz).

    The final image (above right) shows the Macro programming screen, here you can record keyboard commands, not mouse commands. But these can be added in later manually, by simply right clicking on the recorded Macro. Further recording can also be inserted as well as specific time delays.


    Logitech G303 - Gaming Software (Lighting) Logitech G303 - Gaming Software (Surface Tuning)


    The Lighting Settings allow you to control both the illumination of the G logo and the sides of the G303. The colours of these cannot be controlled individually, but they can be made to either just illuminate (your choice of 16.8 million colours) or Breathe (with Brightness and Rate control). The lighting can also be turned off, or controlled via a Sleep Timer.

    Then there’s the Surface Tuning, allowing you to choose from a predefined surface such as Logitech’s own G240 Cloth Gaming Mouse Pad, or calibrate your own. It seems sensible to me that the mouse is in some way bound to the surface that it is on. Whether I could tell a difference between my own mouse mat and the G240 though is up for debate…


    Logitech ARX Control - PC Stats Logitech ARX Control - Mouse


    Overall the Logitech Gaming Software is relatively easy to use, it’s comprehensive and is generic so it integrates with all Logitech peripherals. The ARX software (shown above) for tablets and smartphones is just the icing on the cake.


    Final Thoughts


    The Logitech G303 Daedalus Apex is a damn good Gaming mouse, it’s got the most accurate sensor on the market and tracks brilliantly in Game, but the unusual shape and the high price is likely to put some of you off…

    The Logitech G303 came to pcG in a rather unassuming box, there’s no window allowing you a sneak peek, and when the box was open ‘the birds did not begin to sing’; as the packaging and presentation is a let down and there’s not much in the box other than the mouse! To me, over the last year or so Logitech’s packaging and presentation has gone south, it’s not bad but I expect more from such a premium brand name…

    Luckily the G303 Daedalus Apex doesn’t disappoint, the G303 is a good looking (if not great!) mouse and it’s definitely well made, something we have come to expect from Logitech. But this is another no-frills Gaming mouse, there’s no extra buttons, there’s no weight management and there’s not even a DPI indicator (and the latter does upset me!). The shape is odd too and it feels odd in the hand, especially at first. The back of the mouse seems to push into the back of the hand, and I found myself having to adjust my grip style accordingly. Therefore at first there’s not too much to get excited about…

    After some time though (a day or so) I did warm to the Logitech Daedalus Apex, I found that my bastardized Claw/Palm grip suited the rather odd shape, this is not a mouse for Palm grippers I feel. But what really won me over was the tracking, there’s no doubt that the Logitech (PMW3366) Optical sensor is one of (if not) the best on the market. In Game tracking was spot on, fast or slow, RPG or FPS it made no difference it was like the G303 was wired directly to my brain, I liked it, a lot. Good Tracking is of course one of the most important features of any Gaming mouse, because without it the other guy is just likely to be faster, and we cant have that can we!? 😉

    The problem with the G303 is that other than the tracking there’s not much to get excited about, although I’m sure this was Logitech’s intention; a no-frills, focused Gaming mouse and to that end they have succeeded. And while the Logitech Gaming Software (with ARX Control) is good and the 16.8 million colour lighting is nice the lack of a DPI indicator (although I did get around this, see main review), the badly positioned thumb buttons and the relatively high price puts it up against some very stiff competition.

    The bottom line is that from a pure tracking point of view the Logitech G303 Daedalus Apex is one of the best on the market today. Therefore if that’s your priority then the G303 is well worth a look. But bear in mind that there’s a lot of other Gaming mice out there for less, that still feature good tracking, but also offer up a whole lot more…
