Let’s cut to the chase: the Yunzii IF99 isn’t just another keyboard. It’s the kind of gadget that makes you do a double-take. Picture this—a sleek, snowflake-adorned board with metallic accents that scream “I’m here to make your desk look cooler.” But it’s not all about looks. This 98%-layout keyboard packs a punch with features that’ll make typists swoon and casual gamers shrug, “Okay, this works.”
And at around $100-$120, it’s priced like a budget board but acts like a premium one—minus the fancy aluminum casing, which might irk snobs but won’t empty your wallet. Sure, it’s not perfect. But for anyone who wants a numpad without the full-size bulk, a dash of personality, and a typing experience that’s smoother than your morning latte, the Yunzii IF99 is a breath of fresh (winter) air.
Design & Build Quality
Let’s start with the vibe. The Yunzii IF99 isn’t shy about its winter-themed aesthetic. Picture a keyboard that looks like it was plucked straight from a snow globe—snowflake patterns etched into the keycaps, frosty color gradients (think whites, blues, and grays), and metallic accents that glint like icicles. It’s playful but not overkill, striking a balance between “office-appropriate” and “I definitely bought this for the looks.” The 98% layout keeps things compact compared to full-size boards, but the numpad is still there for spreadsheet warriors and calculator junkies. Also, there’s a magnetic compartment shaped like a snowflake badge that hides the USB dongle.
The case is where things get interesting. It’s plastic—thin plastic—but don’t let that fool you. Yunzii added a metal plate on the top-right corner, giving the board a hefty feel (1.1kg total) that cheaper keyboards often lack. The plastic might not scream “luxury,” but it’s solid enough, with a matte finish that resists fingerprints. The edges are rounded, making it easier to pick up, and the bottom has rubber feet to keep it anchored.
The keycaps are PBT double-shot, which is a fancy way of saying they’re durable and won’t shiny up after months of furious typing. They’ve got a Cherry/ASA-style profile—rounded edges that sit comfortably under your fingertips—and the legends (the letters/numbers) are crisp. The stabilizers (the bits that keep larger keys like the spacebar from wobbling) are pre-lubed, so you won’t hear that annoying rattle some boards ship with.
Now, the elephant in the room: the fixed angle. Unlike many keyboards that let you adjust the tilt, the IF99 is stuck at one angle. For some, this won’t matter—especially if you’re used to typing on a flat surface. But if you’re the type who likes to tweak your ergonomics, it’s a minor letdown. The lack of adjustable feet also means no built-in wrist relief, so you might need a palm rest if you’re logging long hours.
The star of the show, though, is the LCD screen. It’s small—like, really small—but it’s a fun party trick. Battery life, connection mode, macros, or a looping GIF of your cat? It’s all there. The screen’s resolution isn’t mind-blowing (620×280), but it’s bright enough to read at a glance. Just don’t expect to binge-watch it on Netflix.
Yunzii also nailed the little things. The USB-C port is tucked neatly on the side, and the tri-mode toggle (Bluetooth, 2.4GHz, wired) is easy to reach. The board’s gasket-mounted design (rubber layers between the plate and case) dampens sound, giving keystrokes a “thocky” depth without sounding hollow. Even the packaging gets a shoutout—a plastic cover protects the keys, and the included extras (keycap puller, switch puller, spare switches) feel like a bonus, not an afterthought.
Sure, it’s not perfect. The plastic case might feel a step below pricier aluminum boards, and the numpad’s zero key is oddly small (a nitpick for those used to wider zeros). But for the price, the IF99 punches way above its weight. It’s a board that cares about details—like hiding that dongle in a magnetic snowflake—while keeping the essentials, like typing comfort and wireless flexibility, rock-solid.
Software & Customization
The Yunzii IF99 doesn’t just rely on hardware to win hearts—it backs it up with software tricks that let you tweak almost everything. At its core, this keyboard supports QMK and VIA, so you’re not stuck with proprietary apps or clunky interfaces. For the uninitiated, QMK is the open-source godsend that lets you remap keys, create macros, and adjust RGB lighting with minimal hassle. VIA, its user-friendly cousin, simplifies this further with a drag-and-drop interface. Just download the JSON file from Yunzii’s website, load it into VIA, and boom—you’re in control. No coding required, no headaches.
The RGB lighting is where things get fun. With 16.8 million colors at your fingertips, you can dial in anything from subtle pastels to seizure-inducing rainbows. VIA lets you tweak brightness, effects (breathing, ripple, static), and even assign colors to individual keys. Want your WASD cluster glowing red for gaming? Done. Prefer a calming blue wave for work? Easy. The backlighting isn’t just bright—it’s precise, thanks to the diffused switch housings that spread light evenly under each keycap.
Then there’s the LCD screen—a tiny but mighty feature. While it’s not big enough for Netflix (thank goodness), it’s perfect for displaying battery life, connection mode, or macros. The real magic happens when you upload custom images or GIFs via Yunzii’s dedicated LCD software. The process is a bit retro: download the tool from their site, convert your image to 620×280 resolution, and load it onto the keyboard. The screen’s resolution isn’t sharp enough for detailed art, but slapping a looping GIF of your cat or a motivational meme adds personality. Just don’t expect Pixar-level clarity.
The keyboard’s tri-mode connectivity (Bluetooth, 2.4GHz, wired) is managed via a physical toggle on the back. It’s straightforward—no software needed—but the placement might annoy some. Flipping the switch mid-use feels clunky, and the lack of on-board controls for RGB or profiles means you’ll need VIA or the LCD menu for deeper adjustments.
Speaking of quirks, the IF99’s software isn’t flawless. The LCD tool feels dated compared to slicker apps from bigger brands, and the JSON file setup for VIA might confuse absolute beginners. But for most users, these are minor gripes. The ability to hot-swap switches (no soldering!) and customize layouts without spending hours troubleshooting is a win.
Typing Experience & Performance
The Yunzii IF99 isn’t messing around regarding switches—it gives you two solid choices right out of the box. First up, there’s the Gateron Zero Linear, a 45g switch that’s smoother than a buttered slide. It’s pre-lubed, so you won’t hear that annoying rattle or scratchiness some budget boards ship with. The keystrokes feel consistent, and the linear action makes typing or gaming feel effortless. Then there’s the Yunzii Cocoa switch, the brand’s in-house option. It’s also pre-lubed and leans into that “creamy thock” sound enthusiasts geek out over. Both switches are hot-swappable, meaning you can yank them out and swap in something else without soldering.
Typing on the IF99 feels like a dream. The gasket-mounted design (rubber layers between the PCB and case) dampens vibrations, giving each keystroke a deep, satisfying “thock” that’s music to your ears. The pre-lubed stabilizers mean no wobble on bigger keys like the spacebar or Shift, and the PBT keycaps resist shine even after months of furious typing. The sound isn’t as loud as a clicky board, but it’s far from muted—think “library-friendly” but with personality. The 45g actuation force is light enough for all-day typing but still precise enough that you won’t accidentally bottom out.
Gamers, take note: this isn’t a hyper-optimized esports beast, but it holds its own. The 1,000Hz polling rate ensures minimal input lag, and the switches are responsive enough for casual gaming. The lack of adjustable actuation or super-light options might frustrate competitive players, but for folks who game on the side, it’s more than adequate. The numpad is a win here, too—great for MMO macros or quick in-game calculations. The only hiccup? The zero key on the numpad is tiny (1U size), so you might fumble it if you’re used to wider zeros.
Where the IF99 really shines is in its balance. It’s not too heavy, not too light, and the switches are lubed just right. The typing experience is smooth enough for writers but still tactile enough to keep your fingers happy during marathon sessions. And while the plastic case might feel a step below premium, the build quality doesn’t cut corners where it counts—like the PCB, which is rigid enough to prevent flex, or the stabilizers, which stay quiet even under pressure.
Battery Life
The Yunzii IF99 packs a beefy 8000mAh battery—that’s not a typo. For context, most wireless keyboards scrape by on 2000-3000mAh, so this thing is hauling around a power reserve that could probably outlast your laptop. Here’s the kicker: even with RGB lighting cranked to “disco mode” and the LCD screen cycling through GIFs, it still lasts days on a single charge. Turn the RGB down (or off) and stick to Bluetooth, and you’re looking at weeks of casual use.
Charging happens via USB-C, which is about as hassle-free as it gets—no proprietary cables here. The downside? No passthrough charging. You’ll need to unplug the keyboard to juice it up, which isn’t a dealbreaker but might irk multitaskers. A full charge takes roughly 2-3 hours, but honestly, you’ll rarely need to babysit it.

Final Verdict
The Yunzii IF99 it’s a quirky, feature-packed board that punches above its weight in a crowded market. Let’s break down why it’s worth your attention (and why it might make you forgive its minor flaws).
This thing is a looker. The winter-themed design—snowflake keycaps, frosty gradients, and that metallic badge—is playful without being garish. It’s the kind of keyboard that makes your desk feel cooler, even if your actual productivity doesn’t improve (though let’s be real, it probably will). The pre-lubed Gateron Zero and Cocoa switches deliver a “creamy thock” that’s satisfyingly smooth. The gasket-mounted design dampens vibrations, making keystrokes feel premium, and the stabilizers stay quiet—no rattling here. The 8000mAh battery? A beast. It’ll outlast your phone, your patience, and maybe even your will to stop working.
Then there’s the LCD screen—a tiny, charming addition that’s more than a gimmick. It’s not going to replace your monitor, but cycling through battery stats, macros, or a looping GIF of your dog adds personality. Pair that with QMK/VIA support for easy customization (remap keys, tweak RGB, or assign macros), and you’ve got a board that grows with you.
But let’s keep it real. The plastic case, while sturdy enough, feels a step below pricier aluminum boards. The fixed typing angle might irk ergonomics snobs, and the numpad’s tiny zero key takes some getting used to. The RGB backlighting, while bright, isn’t the most vibrant, and the LCD’s resolution won’t wow anyone.
Still, for $100-$120, the Yunzii IF99 is a steal. It’s a numpad board for folks who hate sacrificing desk space, a customization playground for tinkerers, and a typing workhorse for anyone who values comfort. It’s not perfect, but it’s the kind of keyboard that makes you smile every time you fire it up—and that’s worth a lot more than a few nitpicks.
