Zaunkoenig M1K

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

A heads-up before you plow through what made the M1K so special: the M1K is sold out but its successor, the M2K, is available now. Okay, back to the M1K:

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

The electronics inside a gaming mouse are called PCB (short for printed circuit board). A standard mouse PCB would have been way to big and heavy for the M1K. That is why for the M1K we created the worlds smallest gaming mouse PCB. We achieved this by using small components, small traces and then putting it all together very densely:

Some mouse manufacturers like hitting you on the head with how many thousands of CPI the sensor in their gaming mouse. We will just say that the 3360 sensor 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 enable light clicks and to top it all off they will last much longer than Chinese Omrons.

Custom software

We did not stop at custom hardware. The open-source firmware of the M1K is based upon the firmware of legendary user qsxcv and has more than one trick up its sleeve.

Zero latency debouncing

The M1K is probably the first gaming mouse in over two decades that uses zero lag switch debouncing. This means that the method we use to prevent accidental double clicks does not delay clicks by even a fraction of a millisecond. Traditional gaming mouse companies artificially delay mouse clicks by up to 40 milliseconds to prevent accidental double clicks. The result: your reaction time in-game takes a hit.

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 professional 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. That is 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 to reduce every millisecond of latency as well.

Ultra flexible cable

Most gaming mouse cables are either too stiff (braided PVC cables) or too limp (Paracord-style cables). An overly stiff cable will restrict your mouse movements. An overly limp cable however will get in the way of your mouse. Paracord-style cables have the additional drawbacks of scratching on your mousepad and being very fragile.

The M1K cable uses a combination of ultra-fine wires, Kevlar strands and Polyurethane which results in a cable that is not too stiff and not too flexible plus very robust at the same time.

3D-printed bottom shell with Hyperglide mouse feet

The bottom shell of the M1K features a lightweight honeycomb construction and is 3D-printed. 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 was 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:

  • Height: 30 mm
  • Length: 79 mm
  • Width: 60 mm

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.»

The M1K is sold out

We sold the last M1K batch in February of 2021 and we will never restock it. Our new mouse is the M2K:
