I hope you like buttons, because today we're going to take a look at one of the buttony-est gaming mice around, the modular Nyth from ROCCAT. 

Here's how the mouse was introduced to the world back in August:

If you like that epic narration you'll love ROCCAT'S Swarm software, because that same dude will be talking to you through your speakers when you tweak the DPI levels of your mouse on the fly. It's a bit odd, but mostly cool.

The Nyth is called an "MMO" mouse thanks to the side buttons, but that label isn't doing justice to the sheer insanity the Nyth offers. The thumb pad isn't just a set of twelve buttons, it's a fully-modular set up that can be customized beyond anything we've previously seen in gaming mice, and offers potential utility well beyond the world of MMOs.

The Nyth currently sells for $119.99 on Newegg.com.

Features

Let's start with the standard stuff. The Nyth features 12000 DPI "twin-tech laser sensor," customizable button functions, and RGB lighting. All of the settings are controlled through ROCCAT's swarm software, which offers functionality that's generally easy to use. None of the lighting options are particularly spectacular and customizable DPI and button functions are nothing new in the world of gaming mice.

What IS new with the Nyth is the fact that all twelve of its thumbpad buttons can be removed and swapped out for replacements of different sizes and shapes. The Nyth ships with a very nice carrying case packed with six double-sized buttons, three flat non-button row replacements, and twelve flat non-button single replacements. What this means is that you can customize the thumbpad of the Nyth to offer buttons exactly where you want and only where you want. 

This customizability is, to put it mildly, a huge deal. If you're anything like me, thumbpads often feel crowded and clumsy. With the Nyth I was able to clear out the middle row and replace the top row with larger, easier-to-press buttons, and suddenly the thumbpad appealed to a much greater extend than ever before. 

But wait, there's more. Just in case the buttons the Nyth ships with don't provide exactly the customizability you're looking for, you're free to 3D print your own in exactly the color and shape you want. 

The Nyth also features a top fin switch previously seen in the Tyon and a side panel you can swap out to increase the width of the mouse by nearly a third. In terms of features, the Nyth is an absolute winner. 

Design

The Nyth features a matte grey finish that's nicely fingerprint resistant, rubberized black buttons and accents, and a braided cable. All together it's an inoffensive mouse that doesn't do a lot to catch the eye, though you're free to add your own brightly-colored accents to the thumbpad with your 3D printer.

In contrast to many RGB gaming mice, the Nyth doesn't do much to place the colored lighting options front and center. The lighting choices available through the software are limited (especially in contrast to the vibrant visual treat that is ROCCAT's own Kone mouse. On the Nyth you'll see the lights change under the logo on the palm rest and along the horizontal slit on the extreme back of the mouse, but both of those areas are typically covered during gameplay.

Comfort

The biggest asset of the Nyth comfort-wise is the swappable side panel, which is attached via strong magnets. With the smaller panel in place the mouse is sleeker and more agile and good for those with smaller hands, while the larger panel turns the Nyth into one of the widest gaming mice available. This is a great feature in terms of making the mouse more appealing to a wider variety of gamers, though in practice it's likely you'll only use one side panel or the other and never touch the other one. 

The surface of the Nyth feels smooth and sleek, and while I would have preferred a bit more grip on the sides it's a pleasant mouse to use for the most part. The one aspect that wasn't comfortable for me was the top fin below the mouse wheel. I often found it getting in the way of my preferred grip, and as I didn't find a regular use for it (though it can be mapped to whatever function you want, its placement makes it awkard to use) it ended up just getting in the way most of the time. With all the button options offered by the thumpad I really didn't need the top fin, and would have liked the mouse better without it. 

Performance

The Nyth isn't claiming to be the fastest or most accurate gaming mouse arround. Its selling point is its modular nature, first and foremost. Of course, all the features in the world wouldn't be enough to make up for poor performance, and in my time with the mouse I found it to be solid, though unspectacular. 

I used the Nyth to play Blood Bowl IISword Coast LegendsPillars of Eternity, and Unreal Tournament 2004. The side buttons worked perfectly throghout, and clicking with the main buttons felt clear and accurate. I never needed close to the max DPI the mouse provided of course, but I always appreciate being able to set up a "sniper button" for on-the-fly DPI toggling, which the Nyth offers with no trouble.

Again the top fin took a bit of getting used to for my particular grip style, and in general the mouse felt a bit more deliberate than lighter, simpler, more agile options. I never felt that it was hindering my gameplay, but I think the mouse might be best suited to games which can really take advantage of the thumbpad rather than ones that necessitate fast, furious, and exact clicking.
