Closer Look

TT Esports introduces the NEMESIS Switch Optical RGB Gaming Mouse, featuring a patented key-switching system for enhanced gaming. Customizable with up to 12 switch keys, it caters to various playing styles and hand sizes. Utilizing Japanese OMRON switches with a 50-million-click lifespan ensures durability and tactile precision.

The PMW3360 optical sensor offers up to 12000 DPI for superior accuracy. With 16.8 million RGB illumination options, gamers can personalize their battle colors, while software customization allows for profiles, macros, and more.

The mouse boasts Japanese Omron switches with a 50-million-click lifespan, ensuring durability and balanced force distribution for each click. The reinforced key switch design enhances longevity, and in my testing, the mouse proved highly responsive with a satisfying tactile feel. Notably, the right button press produces a slightly different sound than the left.

The TT Esports mouse features a plain black top side with a dragon logo on the rear illuminated in 16.8M colors. A non-illuminated profile change button on the front toggles between 5 pre-configured profiles. The ALPS scroll wheel, also with 16.8M colors, has a patterned rubber top and could be smoother.

WARNING: Potential buyers should take into account the 112-gram weight of the eSPORTS Nemesis Optical switch mouse.

The design favors a palm grip, with a slim middle, widened front, and sloped rear, tailored for gaming. Overall, a well-designed mouse with minor room for improvement in the scroll wheel’s smoothness.

Tt eSPORTS Nemesis Switch

The TT eSPORTS Nemesis Switch Optical utilizes the Pixart PMW-3360 optical engine with a maximum DPI of 12000 in overdrive mode. Default DPI levels range from 400 to 5000 and are customizable through the Command Center Pro software.

PRO TIP: Amp up your gaming responsiveness by setting the eSPORTS Nemesis mouse polling rate to its highest setting, ensuring ultra-quick and lag-free interactions for a competitive edge

The sensor has an IPS rating of 250 and 50G acceleration. The polling rate can be adjusted between 125Hz and 2000Hz. With a 32-bit Microcontroller, this gaming mouse showcases Tt eSPORTS’ serious approach. The design is well-balanced, featuring a sloping top cover and a compartment-like bottom structure.

Looking at the front side, I notice a wave design on the frame, but no RGB illumination. The widened gap between the top cover and the base reveals the Omron switches. The mouse features a braided 1.8m cable, emerging from the left side, and the USB connector proudly bears a dragon logo.

Right Side (Image By Tech4Gamers)

Examining the right side, I observed a slight gap between the top cover and the middle layer. The honeycomb pattern on the middle layer doesn’t cover the entire side, but I appreciate the multi-layered design. Personally, I find a perfect grip with my baby finger resting on the bottom layer and my ring finger comfortably on the mesh design layer.

The ergonomically designed rest plate protrudes from the key switch panel, offering a thoughtful thumb placement during gaming or regular use—a well-executed design. The middle section, adorned with a honeycomb-like pattern, covers the keypad.

Now, for the innovative part—12 buttons are organized in 4 rows and 4 columns. The first row is numbered 1 to 4, and the second row is 5 to 8. To access the last two rows, the slider on the bottom needs to be pulled out. Gripping the ends, pressing, and pulling results in a satisfying click, indicating the slider is fully out and locked.

You can easily configure button combinations by rotating any of the four sliders in upward and downward directions. However, they are not free-floating, so be cautious. Once the lower two rows are visible, you can’t pull the sliders upward, and the same goes for the first two rows in the visible area. The last row is blank, providing four possible button mounts.

After determining your preferred button configuration, push the bottom slider back inside the mouse until the latches are fully inside the bottom frame. This keypad area is the third on the mouse and features RGB backlighting with up to 16.8 million colors. It’s a straightforward process.

Examining the backside, rubber pads on three sides prevent surface scratching. The design features a line crossing pattern, and a sticker on the bottom displays the Tt eSPORTS brand logo, name, mouse model, and serial number under the barcode. The mouse requires 5V with 100mA input power. A slider above the sticker allows for changing the button layout on the keypad.


The TT eSPORTS Nemesis Switch Optical RGB Gaming Mouse features vibrant 16.8 million color backlighting across three zones: the scroll wheel, dragon logo, and keypad with the key switch system. With 5 pre-configured profiles and easy switching, it offers dynamic lighting effects that can be customized using the Command Center Pro. Check out the pictures for a glimpse of various colors and effects.


The TT eSPORTS Nemesis Switch has provided comprehensive software to control each and every bit of the mouse. This software is called Command Center Pro and is available from their website. Let’s take a look at the software interface.

PRO TIP: Adjusting the eSPORTS Nemesis mouse debounce time can fine-tune click precision, reducing the risk of unintended double-clicks during gameplay

Should You Buy It?

So, who should buy the TT eSPORTS Nemesis Switch Optical?

Buy It If:

You are an MMO or MOBA enthusiast: The eight customizable side buttons are a perfect inclusion for anyone who intends on playing MMO or MOBA titles.

✅You want a comfortable gaming mouse: The mouse’s well-built structure coupled with the thumb-rest on the side makes it ideal for those looking for a comfortable gaming mouse.

Don’t Buy It If:

You want a smaller mouse: The TT eSPORTS Nemesis Switch Optical is undoubtedly a bulky mouse, which might not be in line with everyone’s preferences.


The Tt eSPORTS Switch RGB Gaming Mouse left a lasting impression on me with its Japanese Omron switches, promising a remarkable 50 million clicks of durability. During my gaming sessions, the ergonomic design, including a convenient thumb rest and thoughtful curvature, ensured a fatigue-free experience.

What stood out was the patented key-switching system, offering 12 programmable buttons on the left side. Though it took me a bit to get used to, the versatility it provided across different gaming scenarios was worth the adjustment period. The mouse’s accuracy was spot-on, delivering a delightful gaming experience without missing any clicks.

In conclusion, the TT eSPORTS Switch RGB Gaming Mouse isn’t just about impressive durability; it’s a comfortable and versatile choice that caters to various gaming genres. After the initial adaptation, I found it hard to go back to conventional setups, making it my top pick for immersive and enjoyable gaming sessions.
