Tt eSPORTS Nemesis Switch RGB Gaming Mouse Review

When we talk about gaming mouse, the image that strikes our mind is a mouse with a good ergonomic design, accurate and trust-worthy sensor and some extra buttons for macros and LEDs. That’s the image of a general gaming mouse that comes to our mind. And when you narrow it further down into gaming style category, let’s say for MMO style, a mouse with a good number of extra buttons. However, it’s not that often we see something innovative when it comes to mouse. Last time I saw something interesting when it comes to a gaming mouse was detachable keys and modular mouse. And let’s be honest, the type of peripheral this is, there’s not really that much room for innovation in my opinion.

However, today, we are going to take a look at something that’s interesting and one of it’s kind. Today, we are going to take a look at the Tt eSPORTS Nemesis Switch RGB Gaming mouse. What makes this mouse different from others is the patented key switch system design. Here’s what Tt eSPORTS have to say about their new mouse:

The NEMESIS Switch Optical RGB Gaming Mouse comes with an exclusive patented key switching system for an enhanced FPS/RTS/MOBA/MMO gaming experience. Enthusiasts can customize up to 12 switch keys to suit different playing styles, hand sizes, and for enhanced ergonomic comfort. The use of Japanese branded OMRON switches with a 50-million click lifespan provides durable, consistent, and accurate tactile feel with each click for maximum responsiveness; and the use of a PMW3360 gaming grade optical sensor with up to 12000 DPI provides superior accuracy and precision gaming. Equipped with 16.8million RGB illumination, gamers can customize their battle colors for added atmosphere. Additional features such as profiles, macro, lighting effects, colors and button controls can also be customized via software.

Tt eSPORTS Nemesis Switch Unboxing:

Here’s all the stuff that we get with the mouse in a picture.

Tt eSPORTS Nemesis Switch Closer Look:

Here’s a view of the mouse from the front. The wire is coming out of left side of the mouse instead of the middle. What’s also visible in this view is the scroll wheel with rubber material going around along with a pattern on it. Behind the scroll wheel is a button that’s set to profile switch by default and this mouse supports up to 5 profiles. Also, you can see that the left side of the mouse from this picture’s perspective is a little bit tilted downwards.

This is how the mouse looks from behind. There’s the Tt eSPORTS logo that glows in RGB. And it seems like Tt eSPORTS had to drop the honey comb design near this area to make up for the new button design. That feature will be missed, however, I think even if they could implement it, it would make the design a bit crowded.

You can notice the thumb plate coming out of the bottom left of the mouse and how it’s part of the same piece rather than an attachment. Also, if you pay attention to the right side of the mouse, you can see the inside curve near the middle.  Now I have a palm grip and this type of body helps a lot with a better grip of mouse and comfortable positioning of the ring and pinky. And yes, I’m saving the most interested piece for the last.

From this angle, you can see that the left side of the mouse features a dotted pattern design which also helps in the grip sector. Also, from this image, you can see that the mouse features a double inside-curve here that’s great for your ring and pinky finger, This design seems ideal for palm grip, however, for claw grip, you might have to get used to it.

From this angle, you can properly see that the mouse is tilted towards the bottom left corner (top right when facing front) which I think wasn’t visible much in the first image. This is supposed to lower the strain on the mid finger I suppose.

And finally, the sight you’ve all been waiting for. This is what Tt eSPORTS’ all-new patented key switch system looks like. Right now what you’re seeing is only the 8 buttons out of 12 that this system features. Every button has a number engraving on them and are assigned to that number as function as well (till 10 which is set to 0). To access the other four keys, you need to pull the slider mechanism at the bottom of the mouse, set the button orientation as you like by rotating key switches and push back the slider and you’re done. This way, you can set the buttons on this side according to your preference. Also, the mouse features a thumb rest here which adds more to the overall comfortability of the mouse. Due to this, you won’t be rubbing your thumb against the surface which in intense gaming moments can even leave a mark.

Here are some pictures I took of the mouse in different key orientations along with some other images

This is how the bottom of the mouse looks. We have a total of 3 skates on Nemesis Switch. At the bottom is where you’ll find the lever for customizing the key switch system orientation. You just push the lever near the ends inside, and pull it out. Now customize the keys and push back the lever. And below the lever is the information sticker and the Pixart PMW3360 optical sensor seem to have been pushed to right side due to the lever system.

This is how the mouse looks like when the slider is pulled out. You clearly cannot use the mouse like that, and nor is it intended to.

Tt eSPORTS Nemesis Switch Performance:

I’ve been using the Tt eSPORTS Nemesis Switch RGB for more than 2 weeks now and I’ve yet to come across any issue with the mouse. I’ve used the mouse on both the Draconem RGB Cloth Edition and Draconem RGB Hard Edition and the mouse glides and response flawlessly. And just to not leave any speculation behind, I’ve used the mouse on Tesoro Aegis mousepad as well and haven’t come across any issue.

The Nemesis Switch RGB is using 50 million click life cycle Omron switches over 20 million click life cycle switches featured in some of their recent mice we reviewed. This also impacts the longevity of the product. The scroll wheel worked perfectly, however, I still found the Ventus Z scroll wheel a bit more fluid.

The side buttons on the key switch system have a rubberized surface and they feel totally different than the LMB and RMB buttons. And these buttons also require a little bit more force to actuate compared to buttons usually found on other mice on this side, however they worked perfectly.

Command Center Pro Software:

Tt eSPORTS is using an all new software for the Nemesis Switch RGB mouse called Command Center Pro. Unlike their previous software, the Command Center Pro isn’t centralized and only works with Nemesis Switch. Despite that, Tt eSPORTS has done a fantastic job with the new software as everything is laid out perfectly and is self explanatory.

This is what you’ll see when you launch the application. But even before that, you’re most likely to come across the mouse firmware update popup. Anyways, this is where you’ll land once you launch the application; the customize window. From here you can see the mouse in from a top view. The buttons and scrolls on the mouse have been given numbers and you can customize the function of these buttons. You can create new profiles, delete them, copy, import and export them and even link a program to the profile from any window in the application.

Also, you were looking at the front view only in the above picture, this is how the side view 1 and side view 2 looks like.

This is the lighting window where all things related to the lighting effect of the mouse is done. You can find more details about it in the lighting effect section below.

In the performance window, you can customize the various things like the sensitivity, polling rate, button response and angle snapping. The new sensitivity dial seems like a great addition to the software. And you can have up to 4 sensitivity levels set for a single profile. Also, you have the option of disabling the sensor here.

This is the calibration window where you can calibrate the mouse according to the surface you’re using. At the time I was using the Nemesis Switch, the surface I was using was Draconem RGB cloth edition and I didn’t feel a need to calibrate the mouse. And nor did selecting the Draconem mousepad here felt any different.

This is the macro window where you can record and edit macros. Recording a macro is pretty simple, you just create a new macro, press record, input your statement or function and press stop. Now all you got to do is assign the macro to any key on the mouse and you’re good. Also, if you feel like there’s a need for edits, you can edit the delay time after recording or set a delay time by default or completely ignore delay time when recording.


The video quality isn’t the best, but gives you a good idea of what to expect from the mouse. I would advice watching the video in 1080P quality.

User Experience and Conclusion:

So as I mentioned before, I’ve been using this mouse for about 2 weeks and the first thing I want to say is I’m blown away by the comfort and the grip of this mouse. When I first saw the design and the new key switch design, the very first thing that came to my mind was, “it’s not going to be comfortable at all”. But having used it for 2 weeks, I can straight out say that it’s more comfortable than it looks in the picture.

The two inside curves at the right side of the mouse really help a lot with the grip and my ring and pinky fingers feel relaxed. The thumb rest also helps to prevent the thumb from rubbing against the surface. And the tilt near the top right corner of the mouse makes my mid finger feel like weightless, in a good way. This is coming from someone who has a palm grip, now when you consider a claw grip, you’ll have some trouble getting used to the right side of the mouse due to the double inside curve.

The second thing that came to my mind was “it’s going to be very difficult to get used to that many keys on the side.”. And once again, I found myself proven wrong. It didn’t take me much time to get used to the many keys on the side. I mostly play CS: GO which is a competitive online FPS game. Most mice I’ve used usually only come with 2 side button where I bind my smoke and flash grenade. However, I also need quick access to my Molotov which if done without mouse binding, means pressing “4” 4 times in most scenario or press “0” which in an intense moment isn’t possible at all. So binding the Molotov to the side button saved me from a lot of hassle. And this was just one case scenario, having 16 buttons followed by 5 different profile unlocks many possibilities. If you play MOBA or MMO or RTS games, you’ll benefit a great deal with this mouse. Even though I mentioned that I got used to the side buttons in no time, that was the for the 6 keys towards my wrist. For the outer 2 keys numbered “1” and “5”, I had to let go of my perfect grip from the mouse, press the key and get in the perfect posture again. This, in a shooter game, isn’t very acceptable, however, that is something I think doable in various other scenarios. Do keep in mind, you can only use a maximum of 12 buttons at a time since the other four buttons will be hidden.

One thing that could’ve been better with the mouse is how the key switch system felt and the actuation force. They’re not bad, but I think having a lower actuation force and a better tactile feeling would have been better. Also the design could’ve been made a little better to suite the taste of claw grip users as well.

And there’s one thing that I absolutely love about this mouse is the RGB effect. The video embedded above just doesn’t do justice to how awesome this mouse looks in the wave effect when the wave is going through the key switch system. This mouse, in my opinion, makes the most out of the RGB LED compared to the other mouse with RGB LEDs I’ve reviewed.

Using the Command Center Pro application was really easy and very well laid out with everything you need just behind a single wall of window/tab switch.

In the end, it all always boils down to the price. The Tt eSPORTS Nemesis Switch costs only $49.99. At this price point, with the features and comfort level it offers, I would like to rate the Tt eSPORTS Nemesis Switch 4.5 out of 5 stars and give it our Editors Choice Award. If I were to rate this mouse considering only palm grip, I would have given it a solid 5 star Editor’s Choice Award.
