XPG as a company has been on a roll as far as gaming peripherals are concerned. They have already given us the XPG Summoner keyboard and the XPG Precog headset and as we all know, no gaming arsenal would be complete without a good mouse. This is where the XPG Primer comes into play. Now the Primer is a fairly large mouse that is equipped with the PixArt PMW3360 sensor which is capable of up to 12,000 DPI, Omron switches that are rated for 20 million clicks, and full RGB lighting as well. While most mice in the market are made largely out of the cheaper ABS plastic, the XPG Primer, however, uses more durable PBT plastic. Sadly, at the time of writing, there is no software available but XPG has promised us that it will come soon.

Unboxing XPG Primer

Now that we have looked at the specifications, the next step is to start unboxing the XPG Primer. In all honesty, the mouse comes in a rather simple red box that we have grown accustomed to over the past couple of reviews but still, it does the job fine.

If you have seen our previous XPG product reviews, you can tell that he box looks a lot like those, but with a lot less black. Honestly the popping red is not something that everyone is going to like but what can we do.

Opening the flap and you are welcomed by some more information on the mouse which includes the detail about what which button is going to do, and on the right side, you have the mouse sitting under a plastic housing. Pretty simple and effective packaging from XPG.

The back of the box has some additional detail about the mouse, mainly the sensor, RGB lighting, durable Omron switches, and how it is using double shot PBT surface. There is not much to look at, and XPG has decided to keep things simple and straightforward.

XPG Primer Overview

Once you have taken the XPG Primer out of the box, the rest of the affair is pretty simple. You are not getting a lot of accessories, or any accessories, for that matter. Just the usual documentation and a sticker set that XPG is known to include with all their peripherals that I have reviewed so far but aside from that, there is nothing else.

While powered off, the mouse looks as unassuming as you could imagine with the XPG logo slapped on the bottom left and the RGB light strips not so subtly wrapping the sides of the mouse. There is nothing groundbreaking about how the mouse looks but at the same time, we can’t really complain about it based on the price. The mouse itself uses PBT plastic, so the grainy texture is there, which feels slightly rough to the touch but it will not get shiny with your fingerprints over time.

Plugging in the mouse reveals the real light show and the XPG Primer becomes the real star of the show as it starts to show its true colours. I was honestly expecting something a bit subtle, but hey, we are talking about a gaming mouse that ships in a red box. So the subtlety is lost here. With that said, the XPG Primer’s RGB lighting does look good, but sadly, it is currently only controlled through a button with software support promised later on. You can cycle between static, colour shift, and rainbow modes at the moment.

The left side of the mouse is flanked with two buttons that cannot be customized at the moment. However, the light strip is clearly visible with additional branding that is also backlit to give this mouse a character. The side is not rubberized but do have textured feel to it which does something for the grip but do not expect a lot.

Flip the mouse over and you are welcomed with this red bottom with the feet that I wish were a bit bigger. I honestly don’t get why XPG would go for a two tone body design rather than a single, black piece of plastic. Some might like it, I just feel that it is out of place and does not look good here.

XPG Primer Performance

Now XPG Primer, with its price tag, is geared towards gamers and that is what most people plan on doing. However, you have to understand that a lot of us are going to be using this mouse for other tasks as well. For instance, I will be using this mouse largely for gaming and other productivity tasks as well, so it has to perform good in not just gaming but everything else too. Now the star of the show is obviously the PMW 3360 sensor, and the week I’ve spent playing different games with this mouse, I can tell you that it is one of the best sensors and in extension, one fine gaming mouse, as well.

My daily driver is the Razer Basilisk Ultimate and next to that, the Primer does feel a bit cheap but then again, there is a massive price difference between both of the mice, and I am not going to go too hard on the Primer here. Needless to say, if you are looking for something that delivers exceptionally well balanced performance, the XPG Primer is definitely something that you should be looking at.

At the time of writing, you do lack some fine tuning options such as a software to record macros or adjust DPI settings to your heart’s content but we have been told that the software is going to start rolling out soon so for those who are concerned, don’t be. It will arrive soon.

I don’t have much to say about the performance, to be honest. The sensor is the heart of any mouse, gaming or otherwise, and Primer’s sensor delivers the best possible performance you can imagine. I just wish the clicks were a bit quieter because this mouse is one loud puppy when you are clicking away, something I immediately noticed the moment I made the shift from my Basilisk Ultimate.


Honestly though, I have been testing the XPG peripherals for some time now and I can tell you that XPG has their heart and their mind at the right place. For me, the XPG Primer hits the home run on so many great things with top of the line sensor performance, high quality construction, great choice of components, and good enough lighting that it would be a mistake not to recommend this mouse to anyone in the market.

My only issue here is that the mouse has the loudest clicks out of any mouse I have tried and let me tell you I have tried more mice than I can count. Simply put, the XPG primer delivers the performance we all want from a good gaming mouse and I am pleased to announce that you will not be disappointed.
