SpeedLink Decus Gaming Mouse Review

April 10th, 2014 John Leave a comment Go to comments



Picking up where we left off on the SpeedLink Parthica Keyboard Review, we’ll now examine a complementing mouse, styled to match. The Speedlink Decus Gaming Mouse arrived in a funky black and red themed box, with an image of the Decus on the front. Rather than a windowed package, Speedlink have gone for a flip out box.  The main features are immediately obvious:

  • 6 Colour Choices
  • Macro software with 5 Profiles
  • 5000Dpi Laser Sensor

Looking at the back of the box, again key features are covered:

  • Ultimate in ergonomics
  • Ultra-precise laser sensor with adjustable resolution from 400 to 5.000dpi
  • On/off switchable LED illumination with 6 breathtaking colours
  • 7 programmable buttons incl. dpi switch and rapid-fire button

All of the above is listed in a range of languages. Which we’ll cover in more detail soon.

The left side of the box details the Decus’ lighting options, there are six different options on offer.

With the box lid open, we find a mention of the software features (above left). It appears very a similar in design to the Parthica Core software we saw recently.  Again we’ll touch back on this in more detail, later. The mouse is secured in plastic insert keeping it safe and secure during shipping.

Other than the mouse itself, inside the box we have a Quick Install Guide, which covers all the Decus features, warranty and such. The included disc contains the Driver, although the mouse will function (as a basic mouse) without it. To unlock the device’s full potential you’ll need to install it. I will say though, it’s always good practice to download the latest version from the manufacturer when possible. The latest versions can fix issues and on occasion add additional features. At the time of writing the SpeedLink Decus is retailing for approximately £33.

First Impressions


SpeedLink, as I touched upon in a previous review, is a brand that’s not that well known here in the UK. Much like the Parthica it’s another product that seems to have so much on offer but still comes with a very reasonable price tag. With the product unboxed I set about using the Decus for the first time.

It’s such a common and overused statement but really I can’t think of another way to say it; it fit’s like a glove! With my hand placed over the mouse, comfort is the first thought that comes to mind, it feels very natural. Materials and overall product quality appear premium too. Needless to say first impressions are all good.

  • Top

With 7 buttons we’ll examine the top first which houses 5 of them. Looking down at the Decus, it’s separated into multiple sections, each one seems to have a different colour and material. Starting with the left and right buttons -coloured in very vibrant red, curved for your fingers to sit in nicely and coated with a smooth rubberized suface they feel very natural and comfortable.

Our first extra button is placed next to the left click. Usage felt somewhat uncomfortable and difficult. I would much rather this button was a little closer. After using this button frequently it caused my fingers to ache. Moving onto the scroll wheel, it’s also coated in rubber giving much needed grip, this is one of two main lighting areas too.

Below the scroll-wheel is one of the many additional buttons the Decus has. This button is used to switch between Profiles. The preconfigured Profiles each have their own colour and DPI assigned. These can of course be customized to suit.   Focusing now on centre section with the product name “Decus” present, we find a smooth glossy black plastic area, while it looks the part I’m not a fan of glossy in general, we all know why, it’s notorious for attracting finger marks. Moving down further, again coloured in red; this area has a rubberized feel about it also. The cut-out design did cause me some confusion, upon first glance I really couldn’t be sure if it was meant to look that way, or if it had defects! It has a sort of worn paint look about it.

  • Front / Back

Looking at the Decus from the front you’ll notice those curved left and right click buttons once again. There are some obvious manufacturing (purely cosmetic) flaws present in the review sample, particularly on the left click. From this view we see the braided cord for the first time. Covered in nylon and sporting a two tone (black/red) theme with a total length of 1.8m. Around the back you can see the unusual design I just mentioned and the fact it almost looks as if there are defects. I’ve checked and it’s actually meant to look this way! 😉

  • Sides (left & right)

We’ll start on the left first, where the last two of the seven buttons reside. Placement of the two thumb buttons I found to be placed well, using them felt very natural, I didn’t have to reach or move my thumb at all. The whole side is indented allowing your thumb to sit on a recessed ledge, which is backed up with another section below. Unlike some mice I’ve used in the past, your thumb will not make contact with the surface you’re using. Material used is a soft but high grip rubber. The right side is purely for comfort and looks, two sections are moulded for your last two fingers to sit, and like I’ve already stated the overall feel of comfort is just right with the Decus.

  • Underside

The underside is quite generic; 4 glides, a product/serial number sticker and of course the 5000DPI Laser.

Apart from one button that caused me some trouble it’s been all good with the Decus. Next we’ll examine the software and the customization options, as well as the lighting.


Hardware Installation


Installation of the Deucs is handled with a single USB connector attached to a 1.8m braided cord.

Testing Methodology/Setup


Mouse Surface: The Decus was tested using a CM Storm Speed RX mouse mat. The following games were used to help in the evaluation of the product:

  • Titanfall
  • COD
  • League Of Legends


Hardware Performance




Reviewing products like mice is always a tough one, much like a keyboard there’s a transitional period. You’ll know fairly quickly if you like the feel of a product or not, others take some time to adjust to and can grow on you over time. The Decus was an instant hit for me. The ergonomic shape is flawless and comfort is superb, button placement in general is good, with the exception of the button located near the left click. I have average sized hands and I struggled to use this button, you can sit your finger deliberately close to avoid the need to stretch, however due to the curves on the left click, you’ll find once you fingers relax they’ll gravitate away. It’s not a practical button for me.

Sadly their are other problems with the Decus. I found myself irritated by the lighting effects, I saw the same issue on the Parthica Keyboard recently too, it’s the way in which the breathing effect works and IMHO it’s fairly poor. The overall idea is to pulse from no light to full light in a slow and cool motion. That’s not the case though, it blinks from dull to full brightness in a flash and back down at a slow pace. I can only describe it as extremely distracting!

With that all said it’s all positive from here onwards using the Decus has been delightful from gaming sessions to generic tasks.  I allowed myself a full week of usage before tackling any games. Starting with Titanfall; the Decus responded well to fast pace movements, glide and response was flawless. The 5 predefined DPI’s also worked well, I found the sweet spot using the software and adjusted to my needs, hassle free…



The SpeedLink software (not supplied) can be downloaded here, version 1.0 was used throughout testing.


Speedlink Software - default window


Once loaded up you’re greeted with quite a few options, starting at the top left; here you can set Profile names, import and export settings. You can also link a program (Game) to launch from a button. Along the right side of the Window is where control of the Decus’ lighting is handled. The colours available are:

  • Red
  • yellow
  • Green
  • Light Blue
  • Dark blue
  • Purple



The options are good and the effects decent, although light blue and green are too similar to be honest. As there are two main lighting areas, scroll wheel and mouse, you can also blend two colours if you wish to produce some cool effects. Or if you wish, you can set the Decus to cycle of all of the above colours. The lighting effect can be set to OFF, ON or Breathing.


Back to software, in the middle we find an image of the Decus, double click any button to edit their function. Doing so will unlock an additional setting page too, which is split into 4 main sections.



  • Mouse Functions – Assign a button a generic function such as scroll, click, fire or something more handy like DPI Up/Down. A nice tool to have at your disposal when playing FPS shooters.
  • Key Commands – Assign a Keyboard command to a mouse button.
  • Macro Functions – Record and set a macro. Extremely useful, obviously!
  • Basic Functions – Assign shortcuts for multimedia, browser functions, or explorer shortcuts like copy and paste.

All in all a very fair and adequate choice of customization from within the software. The the common core settings of the mouse are separated into the Performance area.


Performance - Speed Performance - System


Under the Speed tab you can access the most traditional mouse settings, Sensitivity for X & Y, DPI, Polling Rate and mistyped “papid fire” whoops! 😉 Rapid fire of course! In the System tab, control of the double click, pointer speed and scroll are available to tweak as you wish.


Final Thoughts


After a testing period of a few weeks, I can say with confidence the Speedlink Decus Gaming Mouse is a great little Gaming mouse. Sure it has silly issues with lighting, they’re not critical but perhaps with future mice from SpeedLink, they can address these and improve. From a comfort point of view the Decus scores extremely highly, with its ergonomic shape fitting my medium sized hands like a glove.

From any angle you glance over the Decus, it looks mean, aggressive but also stylish! Suggesting that there would likely be a high price tag. Seen online at the time of writing for just £33, this is a huge bonus when you weigh up the features vs. the price. Generally the finish and product quality was very high, our sample did have some small cosmetics flaws present though, which lets it down.

Performance wise I have no issues to report and the software couldn’t be easier to work with. It’s laid out well, the options present are more than enough for the average user.

I must mirror what I said about the Parthica keyboard. If you’re looking for a new Gaming mouse and don’t want to invest a ton of cash, the Decus should be on your list to consider.

    It sounds like a great mouse, but I am worried about the size of it. You see, I have quite large hands. That is also the reason that I’m buying a new mouse, it is too small.
    Please awnser me ASAP!

    Hi Martijn and welcome to pcG.

    The Decus is a bit of an odd one if I’m honest and takes some getting used to because of its open palm style. The best way I can describe it, is it’s a bit like placing your hand on a football?!? Given it’s shape it is pretty big though. If you like the style it may be worth checking out Terrys recent reviews on the QPAD 5K and Func MS-3 (revision 2). Personally I rather like the Func.

    Hope this helps!

    I see that you have tested the mouse with League of Legends. I can’t seem to figure out, how to bind the actives, to the mouse. I’ve tried using macro’s (such as setting different buttons to different numbers). Outside League of Legends, it works fine, but once I start a fight, it’s not as reliable. Sometimes it works right away, and sometimes it takes 10 clicks or even more to get it working. Any help?

    Let’s see if we can can get John to answer this one, please bear with us…

    Have you got the same issue with other games, or is this LoL specific. And are you running the latest Drivers and Software for the Decus?

  6. Andreas
    November 1st, 2014 at 10:58 | #6

    Honestly, I haven’t tried playing other games with the mouse. But I’ll try asap 🙂 At the time, I am running fully updated drivers and software. I’ve also tried running older versions in the hope of fixing it.

    Thank you for the help 🙂

    I found that by binding the numbers 1,2,3,4 etc. to the mouse I was able to go into the Settings for League of Legends and set the actives to these numbers, this can be found in the hotkeys menu when you press ‘esc’ in game. From there just click on the abilities/active you wish to re-bind to the buttons on the mouse. Hope this helps…

    Alright, now I have tested the mouse with FarCry3, and it seems to work perfectly, so maybe it’s just a LoL specific problem.

    Thank you for helping Charlie. I’ve tried the method, and it works. But unfortunately not all the time. Sometimes I have to click a mouse button 10 times in a row before the ability/active activates. Not really reliable :'( I’ve tried the exact same method with my old mouse, and it works every time :s

    I have this mouse and seem to experience a lot of problems.

    1stly I can’t bind any game keys (example, an active item to my Mouse button 4/ one of the thump button) but I’ll try to do what Charlie did by binding numbers to them.

    2ndly I can’t use the macro functions of the mouse. I entered a sequence of keys (example velvel witch is a command for laughing ingame. ) and yet when I use the button i have assigned the macro function to, it still only executes its previous function, witch is media-forward. No matter how many times i even use the rapid fire to apply or chose a function, it would not change.

    I have the 1.1 driver version of the mouse’s software. Any help would be appreciated.

      Unfortunately we don’t have this mouse anymore, but this should (and did) work fine. One easy way to check Macros is just program them and then test them in Notepad and you should see your sequence played out…

      Also I suspect that the Macro my be assigned to a specific Profile that you’ll need to be using in order for it to work…

      Hopefully that may help. 😉
