When you talk about PC gaming peripherals, the few brands that will probably come into your mind would be Razer, SteelSeries and Logitech. These are the prominent figures in the gaming industry that have created revolutionary gaming products ranging from Gaming Mice to Keyboards to Headsets. SPRG sent me a reviewing kit of the latest Logitech gaming mouse, and today we will be taking a look at the G502 Proteus Core made by Logitech.
To know why Logitech picked the name of Proteus Core, I dug a bit into the history of Greek mythology and found out that Proteus is the God of River. One of the most interesting things that I found out about Proteus is that he is also known as the god of “elusive sea change”. As water has no shape and form, it is highly versatile and mutable. Simply said, my assumption would be that Logitech created the G502 to be versatile and adaptable to each and every gamer.
When I first started to try a Logitech gaming peripheral, it was the G400s. The ergonomics of the G400s was so good that I could play Dota tirelessly for hours. Compared to the G400s, the G502 looks much nicer and cooler in the aesthetic department. It is also quite a significant upgrade from the G-series mice family with DPI count of up to 12,000. Now that’s a real speedy mouse!
Is the G502 worth the penny? Is the Proteus Core really that versatile to be compared to the Greek god? Is it really an upgrade from its G-ancestors? Let’s take a look and find out!

Unboxing and First Look

The G502 came in a packaging that is of the same style as its family members with black being the background colour with blue sides and outlines. The top part of the box is presented with the G502 in all its glory, with the sides of the packaging showing the technical specifications and requirements. The top part of the packaging also acts like a window flap. Opening it reveals a windowed view of the actual mouse. The back part of the box shows an X-ray view of the mouse, complimented with additional features about the G502.

Included in the package is a set of weights in a small and neat case, the G502, instruction manuals and warranty leaflet. One important thing to note is that there is no disc that contains drivers, which means you probably have to get it off Logitech’s website. Similar to what the other competitors do.

Things that are included in the packaging

The mouse cables are braided which in my opinion was a bit stiff. It might take a few sessions to straighten it out, but on the other hand, it is supposed to last longer than rubber coated cables. Rubber coated cables are known to get sticky in the long run.

Braided USB Cable

The USB connector is not gold plated, which surprised me. Being the latest addition to the Logitech ‘G’ Family and commanding a hundred bucks, I would quite expect the USB connector to be gold plated. Similar priced products from competitors have their USB connectors plated in gold. This is not exactly a deal breaker for any gamers, but it is the expectations that gamers have in gaming peripherals nowadays.
USB Connector

There are a total of 11 buttons, which could be mapped with different functions and we will go into that later. When you plug the G502 into a USB port, the “G” logo will light up. Drivers were automatically installed and the G502 was ready for normal usage. Further mapping of keys and functions have to be done with the software which can be found on the Logitech website.

Now let’s take a look at the G502’s core features and performance.

Ergonomics and Design

The G502 is ergonomically shaped to fit a right-hander. It is quite big in size in terms of the width and length. People with small hands might find using this mouse a challenge. 

Comparison of Size with Razer Krait 2013 Edition

I have a medium sized hand and even so it felt quite big in my hands, occupying the whole of my palms when I use it. It took me roughly 3 days to completely get use to the ergonomics of the mouse and after that, I had not much issue with the comfort that if offers apart from the fact that my palms got sweaty faster when using it. It could be because of the surface of the mouse which traps heat.

Front and SIde view of the G502

The G502 feels like it would suit a gamer with a palm-grip as the surface is quite big, requiring you to rest your palms fully on the mouse when using it. However, it would suit claw-grip gamers too. The sides of the mouse are tapered and you are able to grip the mouse by the sides which will make your hand arch over the mouse naturally. Personally I use claw-grip and I was able to get used to the mouse after a few games.

The sides of the mouse have a rough texture to improve grip. The texture was pretty nice and it does not cause any form of discomfort. 

Textured Sides

 The body of the G502 is dressed in a matt finish, which was both good and bad. Good as compared to glossy finishes, it does not attract fingerprints that easily. The bad part is that sweat stains could sometimes be permanent when used for long period of time. It does attract a fair bit of dust too. When I come home from work I would usually spot dust on the G502. Not exactly an issue, but do remember to either cloth it or keep it away if you’re not using it for a long period of time. 

Matt Surface
Weight-Tuning Mechanism

The weights came in a case which I felt was particularly useful as you definitely would not want to lose those weights even if you are not using them. The case is very slim and compact which signifies that it is suitable for travel.

Weight Tuning Case

The weights are boomerang shaped and have a very slim profile. Each weight weighs 3.6grams and there are a total of 5 weights that you can play around with to suit your gaming needs. In my opinion, the mouse feels quite sturdy even without the weights.

Boomerang-Shaped Weights

To insert weights into the mouse, you will need to turn to the bottom part of the mouse and release a flap door held down by a strong magnet. After which, you will see the skeleton of where the weights could be placed. Placing the weights into the mouse is fairly easy, requiring a bit of force when pressing it in place. Removing it however, was quite a pain. It was literally painful as I had to dig my fingernail underneath the sides of the weight which has a slight gradient to lift it out of its position. The fit was very secure and tight, making removing the weights harder than it should normally require.

Weight-adjusting compartment

People who play FPS games and desire more control and precision are often known to prefer heavy mice to restrict huge movements from the mouse as it glides across the mouse pad. I tried playing a game with all weights set into the G502, and after an hour, I felt that my wrist became tired and sore from the usage. It does however, feel more “solid” and cursor movement was accurate and precise. I preferred the G502 to be lighter, so I removed all the weights. It also resulted in more speed and the G502 was gliding effortlessly. 

Dual-Mode Scroll Wheel

The scrolling function of the mouse was one that I really liked, which had two different modes. They are the infinite scroll mode and the normal scroll mode. The mouse is by default set to the normal scroll mode, which “clicks” for each turn the scroll makes. The infinite scroll mode is without the “click” restrictions, and scrolls at hyper fast speed. To switch between these two modes, there is a button just underneath the scroll wheel. The button sets a mechanism in place to restrict the scroll hence producing a “click” feedback, while another press releases the mechanism and allow for infinite scrolling. It also offers 4-way scrolling, which allows you to scroll horizontally.
One thing however that I disliked about the scroll wheel is the click option. More often than not, a click on the scroll button resulted in a scroll, which in turn causes a miss-click on the intended area. This is a result of the scroll wheel being too sensitive.

Dual-Mode Scroll Wheel


In my opinion, Logitech has really done up the software really well and it seems to be fool proof. After installing the software through Logitech’s website, the software automatically detects the G502, and prepares it to be customized.
You will not need a dictionary to start customizing your 11 buttons with the software as it was really easy to do so. Having used Razer’s Synapse and SteelSeries’s Engine, I would say that the usability of the software is on par. When you move your mouse over to the button you would like to customize, the actual button is highlighted on the image of the G502. Clicking the button allows you to designate specific task or buttons to the selected button. You are also able to set macros to the buttons.

User-Friendly Software Interface

Test Run

After a month of testing, I found out that my hands have really adapted to the mouse, making movements on the mouse seem like fluid. My wrist did not feel any strain after a 3 hour gaming session. The clicks also actuate effortlessly, allowing for faster response. The extra buttons were pretty useful, but not all of them as I did not require so many buttons for Dota 2 which is a MOBA genre game. A MMORPG player would truly appreciate the true beauty of the extra buttons, as they are placed very conveniently around your thumb and index finger.  
Even though the G502’s DPI count goes up to 12,000DPI, I found that 4500DPI was the maximum I ever have to go, as any higher than that, a slight movement of the wrist will cause the cursor to fly a few kilometres. (Exaggeration intended) The high DPI count felt more like a novelty rather than functionality as you will seldom need the mouse DPI to get to that level.
The clicks sound slightly louder than my Razer Krait 2013 Edition and Deathadder 2013 Edition. As Dota 2 requires many clicking action, the noise produced by the clicks became quite audible. Not to the extent you will want to put on a headphone just for that, but it can get irritating.


Priced competitively at a price of $99, the Logitech G502 has pleasantly surprised me till no ends. To be named after a Greek God, the G502 definitely lived up to its name. The G502 was very easy to use albeit it being a bit bulky. People with smaller hand size might want to steer clear from this mid-sized giant as I predict it will cause a huge amount of stress on your wrist and hands, tiring your hands out faster. The braided cables were a bit too stiff than it should be, but if you are exchanging that for a longer lasting cable then I would think it’s a fair trade. The matt finish traps heat and causes your palms to sweat up faster, which in turns offer a better and more comfortable grip. The scroll wheel is unique, but clicking it causes the wheel to move as the wheel is too sensitive. If you have the luxury of the cost, then the G502 will not disappoint you. There are features which could be better, but the overall comfort and features it offers is too good and it covers the flaws. As with the improvement of the G400 gaming mouse being named as the G400s, I do hope there would be an improvement in the next upgrade, making the G502 one of the legendary gaming mouse in the gaming peripherals industry. I would rate the G502 as an expert gaming mouse because of the features it offers.
