The Zaunkoenig M1K is the lighest gaming mouse in the world: it weighs just 23 grams. It is also the first carbon fiber gaming mouse and the first dedicated Fingertip Grip gaming mouse.

Level up your aim with the worlds lightest gaming mouse

At 23 grams accelerating and stopping the M1K feels almost instantaneous. Put another way: the M1K is really good for aiming. We achieve this low weight not only by using carbon fiber, but also by removing mouse features that do nothing for your aim: RGB lighting, sniper buttons, side buttons and the mouse wheel.

So how do 23 grams feel? See this post by LazerDoofus on r/MouseReview:

«My M1K clocks in at 21.9 grams on the scale I use for my coffee every day. I expected this mouse to feel much lighter than my other mice, but it’s more significant than that. It is in fact so light it almost has functionally no weight.»

Plastic does not cut it

We could not have reached 23 grams without the help of carbon fiber. With its insane stiffness carbon fiber enables ultra lightweight designs compared to traditional plastic. The reason every other gaming mouse out there is made from plastic is not because plastic has great material properties. The reason instead is that plastic is cheap to produce. While a carbon fiber shell has to be baked for hours under high temperature and pressure, a plastic shell is made in a few seconds.

Custom hardware

When trying to make the best possible mouse for aiming, the printed circuit board (PCB) is just as important as low mouse weight. What good is a lightweight mouse, when the PCB itself has high input lag? At the same time we had to keep the PCB small, in order to save weight.

We managed to create a small PCB that at the same time has extremely low input lag by choosing top-of-the-line components and creating a densely packed PCB, so that no space is wasted:

Some mouse manufacturers like hitting you on the head with how many thousands of CPI their gaming sensor has. We will just say that the 3360 inside the M1K has enough CPI. Whats more important than the sensor anyway is that we chose the best possible switch for the M1K: the Japanese Omron D2F-01F. Through their complex mechanical design and their thick gold contacts Japanese Omrons not only provide incredibly rich feedback, they also are enable light clicks and to top it all off they will last much longer than Chinese Omrons.

Custom software

We didnt stop at custom hardware. The open-source firmware of the M1K is based upon the firmware of legendary overclock.net user qsxcv and has more than one trick up its sleeve.

Zero latency debouncing

The M1K is probably the first gaming mouse that uses zero lag switch debouncing. Traditional gaming mouse companies artificially delay mouse clicks by up to 40 milliseconds to prevent accidental double clicks. It is kind of hilarious that many gamers out there have quicker pings than mouse clicks. M1K clicks on the other hand will have a latency of around 0.55 milliseconds (when being used at 1,000 Hertz) or 0.11 ms (when being used at 8,000 Hertz).

Install nothing

You can change CPI, Angle Snapping or LOD without having to install software on your PC. This is not only convenient, but more importantly crucial for pro gamers that are usually not allowed to install software on competition PCs.

Overclock to 8,000 Hertz

High refresh rate gaming monitors are becoming more and more common. We think a 500 Hertz mouse is the equivalent to a 60 Hertz monitor: outdated. Thats why internally the M1K runs with 8,000 Hertz. When you are willing to overclock your Windows driver you can actually use the M1K with 8,000 Hertz in Windows.

Using the M1K at 8,000 Hertz as opposed to 1,000 Hertz reduces input lag by 0.4375 milliseconds on average; compared to 500 Hertz mice, the M1K will be quicker by 0.9375 milliseconds on average. We worked hard to not only save every gram of weight on the M1K, but reduce every millisecond of latency as well.

Ultra flexible cable

Traditional gaming mouse companies usually use cables that are way too stiff and heavy. This is due to using very few and thick copper wires which are cheaper for them to produce. Making matters even worse, most traditional gaming mouse cables use a cheap plastic jacket made out of PVC. Some traditional gaming mouse companies then go the extra mile and encompass their creation with a nylon braid, for that extra bit of stiffness. You end up with something that feels more like a lightning rod than a mouse cable.

Paracord-style cables on the other hand are often too limp: they do not move enough when you move your mouse and can get in the way. Also Paracord-style cables will create a scratchy sensation on your cloth mousepad.

This is where the cable of the M1K comes into play. To make the cable of the M1K flexible, but not too flexible, we started at the core of the cable: the copper conductors. We use very fine copper wires, instead of thick ones. Whereas a normal gaming mouse cable has 28 copper wires inside of it, the cable of the M1K consists of 76 copper wires. For the jacket we went with the modern material polyurethane, which pulls off the feat of being flexible yet robust at the same time. Polyurethane also has a wonderfully slick surface, ensuring scratch free gliding over your mousepad. We use gold plated crimp terminals from Molex to connect the cable with the PCB:

3D printed bottom shell with Hyperglide mouse feet

The bottom shell of the M1K features a lightweight honeycomb construction and is printed from white ABS. Hyperglide makes the mouse feet of the M1K. Hyperglide mouse feet are famous for their rounded edges, which ensure scratch-free gliding.

Dedicated Fingertip Grip design

We think Fingertip Grip is the best mouse grip. The M1K is the first gaming mouse that is designed purely for Fingertip Grip. The M1K is not compatible with Claw Grip and Palm Grip. For optimal performance you have to design a thing to be just one thing. Just imagine an off-road vehicle that is also designed to be a racing car. A gaming mouse that works with Palm Grip and Fingertip Grip is not optimal for either of those grips.

So how does a dedicated Fingertip Grip design look like? Short and not very tall. Take a look at the M1K dimensions:

A tall mouse would result in your wrist being bend up constantly, increasing the strain on your wrist. Just try it out: bend your wrist up and hold it like that for a minute.

A long mouse would restrict your movements. When you pull a long gaming mouse towards you, the back of the mouse collides with the inside of your palm. Put differently: long mice restrict your vertical range of motion.

So how does it feel when you use Fingertip Grip with the M1K? Swithwother on r/MouseReview describes it like this:

«For any fingertip grip user it is a dream come true. It feels like u have nothing in hand. It’s going to sound cringy but it feels like u are moving the crosshair itself with only ur hand.»
