Update: The M2K is sold-out forever. In 2023 we will launch two new gaming mice: the Zaunkoenig M2S as well as the Zaunkoenig M3K, starting with the M2S in the second quarter of 2023.

A first principle design

While all other gaming mice out there look like they have come off the exact same manufacturing line, we have taken a first principle approach for the design of the M2K. Ask yourself: what are the most precise tools humans have? Not your palm, not your arm, but your fingers. More precisely: your fingertips.

That is why the Zaunkoenig M2K looks so different from any other gaming mouse. The design of the M2K serves one singular purpose: to enable you, the gamer, to aim with pinpoint accuracy.

When other companies tell you their mouse is usable with Claw Grip, Palm Grip and Fingertip Grip at the same time, just know they are trying to sell you a toaster that can brew coffee, cook the perfect steak and grow herbs at the same time. That’s not how it fucking works.

With just 24 grams the Zaunkoenig M2K is the lightest gaming mouse in production. And it is not even close. Other features of the M2K are a ceramic coated wheel as well as driverless 8,000 hertz.

The Zaunkoenig M2K is the fastest gun in the West

Precision comes through aiming with your fingers and your fingertips. But how can a gaming mouse enable you to be the quickest draw in the West?

There is only one way to be faster than your own shadow: Reduce the weight of your gaming mouse. The lower, the better.

That’s why we have designed the M2K to be as light as possible. The mouse wheel weighs less than a single gram. The M2K is unfathomably lightweight at 24 grams, which is less than an ounce.

Carbon fiber: the material for rockets, hypercars and your next gaming mouse

Conventional gaming mouse companies desperately try to be lightweight by drilling holes in their mice, often to the detriment of your ability to properly grip the mouse.

That is not the Zaunkoenig way of going about things, and thus we have spent years of development to create a carbon fiber shell that is extremely lightweight and stiff at the same time. Carbon fiber is the material that Elon Musk uses to shoot rockets to space. We like shooting things too. (Elon, if you are reading this, we want a Zaunkoenig M2K to go to Mars, contact

We took care of the little things too: PTFE feet that are located perfectly in the corners and that don’t cover screws. (Other gaming mouse companies don’t want you to open up their mice and thus put mouse feet over screws.)

Available with a sandblasted finish

As of 2022 the M2K is only available in a sandblasted finish. We previously offered the M2K in a glossy finish but we have come to the conclusion that sandblasted is just better than glossy. That is why we will not offer glossy M2Ks any more.

A sandblasted M2K has a slightly rough and chalky feel to it, giving you excellent grip even when you sweat a lot and live in a humid climate. Just looking at the sandblasted finish feels grippy already:

Made in Germany

The carbon fiber unibody, the printed circuit board (PCB), the cable as well as the final assembly are all made in Germany. Every M2K goes through our hands and only gets shipped when we deem it perfect.

Driverless 8,000 hertz

The Zaunkoenig M1K was famous for having the lowest latencies of any gaming mouse. With the M2K we took it one step further and gave the M2K driverless 8,000 hertz. Meaning: if you want to use 8,000 hertz on the M2K you do not have to install software or drivers (more on that here).

In order to being able to use 8,000 hertz we had to use what probably is the world’s most overkill gaming mouse MCU:

This picture shows the MCU of the Zaunkoenig M2K.

The ARM MCU inside the M2K is a 216 MHz beast from STMicroelectronics. This MCU is so overkill, that the company we bought the MCUs from wanted to know what we were going to use it for, before shipping it to us. Apparently this MCU is so powerful, that you could build military drones with it.


What pros and reviewers say about Zaunkoenig mice

nOted, professional Valorant player:

«I have been using the M2K for the past 6 to 7 months, and it is alien tech, it is almost unfair how good it is. If you play fingertip grip it is heaven on earth.»

Optimum Tech, YouTube tech reviewer:

«Very rarely do I pick up a mouse and on the first day see a bump to all of my [Kovaaks] scores. The only time this has happened was with the G Pro Superlight. And now also with the Zaunkoenig M2K. More importantly, when it came to actual gaming, this thing felt great. In fact, in terms of aiming and just general movement this is the best mouse that I have ever used. Aiming just felt very natural.»

NotSoCommonSense, YouTube mouse reviewer:

«The M2K has the best clicks I have ever felt. The M2K has the best shell I have ever felt, as far as the feeling of the coating and the overall feeling of the mouse. The scroll wheel feels really good. The only thing I would say that isnt best in class I have ever felt is the wire. I think everything else about it is God-tier. Even the feet.»

SpiLLi, YouTube mouse reviewer:

«This is the most connected I have ever felt to a mouse … [I am not talking about] trying to take it on a date, but it means whenever I actually use the mouse it feels like a legitimate extension of my hand. I have never really had that experience with any other mouse, even the super light ones like the HSK or Starlight-12 [which feel] good and […] very quick and very lightweight, but [they do not feel] like there is nothing there. And I really get that feeling with this mouse.»

KraftyCraft, YouTube mouse reviewer:

«My biggest takeaway from using this mouse in-game is this feeling of complete connectedness. I know this sounds so corny, but it feels like I am not using a mouse at all … Aiming is just using my hand. This allows me to completely focus on the actual game that I am playing. I can zero in on what I actually need to do to frag out, instead of focussing on using a tool. It just puts me into another level, I love this in-game. It feels so intuitive, it feels so sharp, all my movements are so precise, I can just focus completely on the game that I am playing, which is something I have not found with any other mouse. It just feels so effortless

The difference between a 24 gram mouse and a normal 60 gram mouse is huge. So huge in fact, that we are convinced that once you have used a 24 gram mouse, going back to 60 gram will be painful.

We are so sure of that, that we offer a 30 day return period: should you buy the M2K and not feel the difference to your normal gaming mouse within those 30 days, you can return the M2K and will get back those 299 Euro. No questions asked.

Product warranty

The M2K is very durable: the carbon fiber shell is super-tough. The cable is protected by Kevlar strands. The PCB is soldered in a Germany factory with German precision equipment. The switches in the M2K are made in Japan and have thick gold alloy contacts protecting them from oxidation.

We are thus very confident in giving a warranty of two years. We think this is a conservative value: the M2K likely will live much longer.

How long does it need before we ship your M2K?

A September order has an estimated delivery of January/February of 2023. Due to high demand we decided to stop selling the M2K for all of October, to give us a chance to catch up with orders from July, August and September (yes, our backlog is that big).

Free worldwide shipping

Shipping is free. We ship to many countries all around the world, including the US, Canada, Russia, Japan or South Korea. Every M2K parcel comes with a tracking number and is insured.
