Your keyboard may be one of the most-used pieces of technology on your desk.
Whether you're working through emails, studying for an exam, editing content, gaming after hours or switching between multiple devices throughout the day, the right keyboard can make your setup feel faster, cleaner and more enjoyable.
But there's a catch.
Traditional full-size keyboards take up a lot of desk space. Wired keyboards add another cable to an already crowded setup. And if you regularly move between a desktop, laptop, tablet or other devices, repeatedly changing keyboards can become frustrating.
That's where a compact wireless keyboard can make a real difference.
The FREEWOLF M75 Pro, available at Sanrux, combines an 82-key compact layout, 2.4GHz wireless and Bluetooth connectivity, multi-device switching, colorful backlighting, PBT keycaps, a multifunction control knob and an integrated status display in one distinctive keyboard.
It's designed for more than one kind of user—and more than one kind of desk.
What Makes the FREEWOLF M75 Pro Different?
At first glance, the M75 stands out because of its colorful illuminated keys and compact design.
Look a little closer, however, and the practical features become more interesting.
The keyboard uses an 82-key layout, reducing its footprint while retaining many of the keys people use regularly. FREEWOLF's documentation lists dimensions of approximately 360 × 147 × 43 mm and a weight of around 600g. (Manuals+)
That makes it an interesting middle ground between a large traditional keyboard and an ultra-minimal keyboard that removes too many useful controls.
You get more room on your desk without reducing the keyboard to the bare essentials.
For gamers, that extra space can mean more freedom for mouse movement.
For professionals and students, it can simply mean a cleaner workspace.
Dual-Mode Wireless: Bluetooth 5.0 + 2.4GHz
One of the strongest features of the M75 is its flexible wireless connectivity.
The keyboard supports both Bluetooth 5.0 and 2.4GHz wireless connections. (Manuals+)
Why have both?
Because different situations call for different connections.
2.4GHz wireless
The included USB receiver gives you a straightforward wireless connection for a compatible desktop or laptop.
The receiver can be stored in a dedicated compartment underneath the keyboard when you're not using it, which is a nice little detail for anyone who has ever lost one of those tiny USB dongles. (Manuals+)
Bluetooth
Bluetooth is particularly convenient for laptops, tablets and other compatible Bluetooth devices because it doesn't necessarily occupy a USB port.
Instead of being tied to one connection method, you can choose whichever works better for your setup.
One Keyboard, Multiple Devices
This is where the M75 becomes especially useful for people with more than one device.
The keyboard supports one 2.4GHz connection plus two Bluetooth channels—BT1 and BT2. That means it can be paired with up to three devices across those connection options and switched between them using the keyboard's connection controls. (Manuals+)
Imagine your everyday setup.
Your desktop computer uses the 2.4GHz receiver.
Your laptop is paired to BT1.
Your tablet is paired to BT2.
Instead of keeping several keyboards on your desk—or repeatedly going through a new pairing process—you can move between your connected devices from the M75.
For people who work across multiple screens and devices, that's more than a flashy feature.
It's genuinely useful.
A Compact 82-Key Layout That Saves Desk Space
A large keyboard isn't automatically a better keyboard.
Full-size layouts are useful when you need every dedicated key and a separate number pad, but they also occupy considerable desk space.
The M75's 82-key compact layout is designed to reduce that footprint while retaining frequently used keys and dedicated arrow controls. (Manuals+)
The result is a keyboard that can work well in smaller home offices, gaming desks, dorm rooms and shared workspaces.
It also leaves more space beside the keyboard for your mouse.
That's particularly attractive to gamers who use broad mouse movements, but even outside gaming, a less crowded desk simply feels better to work on.
The Smart Display Keeps Important Information Visible
One of the most distinctive elements of the M75 is the small integrated display beside the keys.
Rather than making you guess what's happening with the keyboard, the display provides useful status information including battery level, charging state, low-battery warning and the active wireless connection mode. (Manuals+)
So if you're wondering whether you're connected through 2.4GHz, BT1 or BT2, you can check the keyboard.
Likewise, you can see the battery status without waiting for the keyboard to unexpectedly stop working.
It's a small feature that makes wireless operation feel much more transparent.
Take Control With the Multifunction Knob
Next to the display is another useful feature: the multifunction control knob.
According to FREEWOLF's documentation, rotating the knob adjusts volume while pressing it provides mute/unmute control. (Manuals+)
That means you don't need to interrupt what you're doing to hunt for an on-screen volume slider.
Listening to music while working?
Turn the knob.
Game suddenly too loud?
Turn it down.
Need immediate silence during a call?
Press to mute.
Simple controls like these can become surprisingly useful once they're sitting directly at your fingertips.
RGB-Style Lighting That Gives Your Desk Personality
Of course, we can't talk about this keyboard without talking about the lighting.
The M75 features vibrant multicolor backlighting with adjustable brightness and lighting effects. (Manuals+)
For gamers, illuminated keys can complement an RGB gaming setup.
For creators and students, they can turn an otherwise ordinary workspace into something more personal.
And for anyone working in a dim room, illuminated keys can also improve key visibility.
The effect is particularly striking with the gradient keycap combinations shown in the different M75 color variations.
It's functional—but it's also fun.
And desk accessories are allowed to be fun.
Durable PBT Gradient Keycaps
A keyboard is something you physically touch thousands of times.
Keycap material therefore matters.
The M75 uses PBT gradient keycaps, which FREEWOLF describes as durable, comfortable to touch and resistant to oil and wear. (Manuals+)
PBT is popular for keyboards because it generally holds up well to repeated use.
For someone typing, studying or gaming for hours at a time, that durability can be more meaningful than it initially sounds.
The gradient designs also give the keyboard much of its personality, especially when combined with the backlighting.
Built-In Rechargeable Battery
Wireless freedom isn't particularly useful if your keyboard constantly needs to be charged.
FREEWOLF documentation for the M75 lists a built-in 2000mAh lithium battery and USB Type-C charging. (Manuals+)
The integrated display also makes battery management easier because you can monitor the remaining charge instead of relying on guesswork.
Battery life will naturally depend on factors such as backlight use, brightness and connection conditions, so actual runtime can vary.
Turning down or switching off lighting when you don't need it can also help extend wireless use between charges.
A Keyboard for Gamers
Gaming is one of the obvious uses for the M75.
The compact layout creates additional mouse space, while the 2.4GHz wireless connection provides a dedicated receiver-based option for compatible gaming PCs.
The multimedia controls make adjusting audio convenient, and the colorful illumination fits naturally into a gaming setup.
The 82-key design also keeps important directional and function controls accessible without the footprint of a traditional full-size board.
Whether you're playing casually after work or building a dedicated gaming desk, the M75 offers a nice balance between functionality and compact size.
A Keyboard for Work and Productivity
The M75 isn't just a gaming accessory.
In fact, its multi-device functionality may be even more useful during a working day.
Picture a home-office desk with a company laptop and a personal computer.
Instead of keeping two keyboards in front of you, you can pair the M75 with both and switch connections when needed.
The compact layout frees up working space, while the control knob gives you quick access to audio during calls, videos or presentations.
And because it works wirelessly, your desk doesn't need another permanent cable running across it.
A Keyboard for Students
Students increasingly move between several devices.
You may write an assignment on a laptop, research something on a tablet and use another computer for a different project.
A multi-device wireless keyboard makes that setup easier.
The compact size also makes the M75 practical for smaller desks in bedrooms, apartments or dorm rooms.
Add the colorful lighting and customizable-looking aesthetic, and it becomes a piece of study equipment that doesn't have to look boring.
A Keyboard for Creators
Content creators, editors and digital professionals often work across multiple screens and devices.
The M75's combination of multi-device connectivity, compact size and direct multimedia controls can fit naturally into that environment.
The multifunction knob is particularly convenient when you're working with audio or video and want immediate volume control.
Meanwhile, the smaller footprint leaves more room for a mouse, drawing tablet, control surface or other creative equipment.
Designed for Different Setups and Styles
One of the nicest things about this keyboard is that the different color combinations can change the personality of an entire desk.
Based on the product imagery, the M75 range includes distinctive styles such as Moon Night, Grape Purple and Blackberry, ranging from relatively neutral gray tones to much more colorful purple and pink combinations.
The choice isn't simply about function.
Your keyboard sits in front of you for hours. There's nothing wrong with choosing one that actually looks like it belongs to you.
Pair Moon Night with a minimalist workstation.
Use Grape Purple for a colorful gaming or creator setup.
Or choose Blackberry when you want something playful and bold.
Is the FREEWOLF M75 a Mechanical Keyboard?
This is one specification where I want to be particularly careful.
Some online listings and promotional wording describe M75 keyboards using terminology associated with gaming or mechanical-style keyboards. However, documentation for the FREEWOLF M75 version matching these specifications lists its operation style as membrane, and another M75 manual explicitly lists switch hot-swap as “No.” (Manuals+)
For that reason, I would not market this particular Sanrux version as a mechanical or hot-swappable keyboard unless your supplier provides documentation confirming that your exact variant is different.
Accurate product claims are better for customer trust—and save headaches later.
Who Is the FREEWOLF M75 Best For?
The M75 makes the most sense for someone who wants a compact keyboard without giving up useful controls.
It's particularly attractive for:
- Gamers who want more mouse space and a colorful wireless setup.
- Professionals switching between work and personal computers.
- Students who use laptops, tablets and multiple devices.
- Creators who appreciate quick multimedia controls.
- Home-office users trying to reduce desk clutter.
- Anyone who likes RGB-style desk setups but still wants practical productivity features.
It's that versatility that makes the keyboard interesting.
The M75 doesn't force you to choose between something that looks good and something useful for everyday work.
