I really enjoyed reviewing the Tt eSPORTS Nemesis Switch Optical RGB as it is a very interesting and pretty unique mouse. There are a number of similar choices out there, but the greater part of them lack a proper high-end sensor. Also, the shape can and should be a determining factor, and most of these MMO-oriented mice are rather large, while the Nemesis remains inside the medium area size-wise. The shell is very well made, and the grooves are nice and comfortable.

Surface coatings can be quite controversial as some people prefer rubberized materials, some go with matte surfaces, and some like a nice glossy finish. This mouse features a top coating that is pretty much a transition between a matte and glossy one, and it also doesn't seem to collect fingerprints easily. The materials are nice and pleasant, and the build quality is almost seamless despite the rattly scroll wheel. The weight is an intuitive factor when choosing mice, but generally, lower is better over the long term. The Nemesis weighs about 112 grams with the first few centimeters of its cable included, so it's quite heavy given its size, but most similar mice with a lot of buttons aren't really lightweight either.

Moving on to the sensor, most of the 3360-equipped mice perform pretty much perfectly, and the Nemesis Switch Optical RGB is no exception. Aside from the smoothing issue that causes +2 ms input lag above 2000 CPI, it is flawless. I encountered no anomalies or malfunctions during testing and some intensive FPS gaming.

As for the buttons, the main ones are fantastic. They have a medium tension (a tiny bit higher than on the Iris Optical, but lower than on the Ventus X Optical), are tactile, spammable, and just feel great overall—they also have a high nominal lifespan of 50 million clicks. The scroll wheel is great as well, and it uses an Alps encoder, which is considered one of the best both for durability and feeling. The side buttons are many, but they can be reduced to half of their original number. With the unique, rotatable panel switch design, you can choose between 1 or 2 buttons on 4 panels in total. This is a great idea for customization, although also what makes the mouse a bit heavy and a little unbalanced. The click-feel of these buttons is something I found to be mediocre, but this is up to personal preference as well. I like lighter clicks, especially if I want to spam them, and these are pretty heavy and stiff.

There are three big mouse feet at the bottom of the shell that glide smoothly with medium friction—aftermarket pure PTFE feet glide way faster and I am used to those, but as for stock feet, these are pretty good. Unfortunately, there are no replacement feet in the box by default, so if these wear out, the aftermarket ones are the only option. The cable is rather stiff, thick, and braided, which can be considered good and bad. I highly prefer non-braided ones because they generally are way more flexible. If you have a bungee or secure the cable in place somewhere, it shouldn't really cause any issues, and its 1.8 meters length should be enough for everyone.

The driver software, Tt eSPORTS Command Center Pro, has some minor bugs, but overall, is perfectly usable; however, I would like to see a reworked, more visually pleasing version of it. If you feel like it, you can delete the program after setting everything up to your needs because the mouse has on-board memory to which all settings are saved. This is useful for when you move from one computer to another quite a lot. Less and less mice lack RGB elements nowadays and of course, the Nemesis isn't one of them. There is a huge amount of possible configurations with the three-zone, 16.8 million colors illumination. The side buttons can each be set to a different color, which pretty much means that there are more like ten instead of three zones here.

Overall, despite some minor weaknesses, the Tt eSPORTS Nemesis Switch Optical RGB can be a perfect companion for playing game or using graphical and other designer programs that require a ton of keybindings. It performs perfectly, has a great amount of customization—both in terms of hardware and software—and uses great materials. If the shape suits you, it can be a top choice.
