Zornher ZH870 Keyboard Review – Honest Verdict on the Viral TikTok Mechanical Keyboard

Quick Answer: Should You Buy the ZH870 Keyboard?

The Zornher ZH870 keyboard is worth buying at $90-100 for first-time mechanical keyboard users and aesthetic-focused buyers who prioritize sound and looks. Avoid at $130+ — you’re paying a “TikTok tax” for a likely rebrand of the Aula F99 Pro. The ZH870 delivers on its viral promises (creamy sound, stunning keycaps, tri-mode connectivity) but falls short on build materials (plastic enclosure) and lacks long-term reliability data.

Best For: Casual gamers, productivity users, content creators needing photogenic setups
Skip If: You need metal construction, competitive gaming features, or established brand reliability

This comprehensive ZH870 keyboard review covers everything buyers want to know about the Zornher ZH870 mechanical keyboard, including sound quality, battery life, wireless performance, software issues, ZH870 keyboard price analysis, and whether this viral TikTok keyboard is actually worth buying in 2025. If you’re searching for an honest Zornher keyboard review before spending $90–$135, this guide answers that clearly.

What Is the Zornher ZH870 Mechanical Keyboard?

The Zornher ZH870 (also sold as “Zornher Prism”) is an 80% TKL mechanical keyboard that exploded on TikTok and Instagram in 2024-2025, accumulating over 100 million views. Manufactured by Zornher, a relatively new Chinese brand, this ZH870 keyboard gained viral status for its “creamy” factory-lubed sound profile and distinctive IMD PBT keycaps featuring topographic, gradient, and spider web themes.

ZH870 Keyboard Specifications at a Glance

Source: Zornher official specifications, verified across Amazon and AliExpress listings (December 2025).

First Impressions: Unboxing the ZH870 Keyboard

What’s in the Box?

• ZH870 keyboard with pre-installed switches and keycaps
• 2.4GHz USB wireless receiver
• 1.8m nylon braided USB-C cable
• Keycap and switch puller
• User manual (some users report Chinese-only versions requiring translation)

Build Quality: Premium Feel, Budget Materials

The Good: The ZH870 feels surprisingly solid in hand. The aluminum top plate provides rigidity and prevents flex during aggressive typing. At 2.54 lbs, it’s hefty enough to stay planted on your desk without sliding. The gasket mount delivers a soft, cushioned typing experience that enthusiasts describe as “marshmallow-like.”

The Reality Check: The enclosure is plastic, not metal. While the aluminum plate adds structure, the overall chassis feels “budget” compared to $100+ keyboards like the Logitech G413 (brushed aluminum top) or the ND75 (full metal housing). One Reddit user aptly summarized: “It looks premium in videos, but feels like a plastic board when you hold it.”

ZH870 Keyboard Sound Test & Typing Experience

The “Creamy” Sound Profile Everyone’s Talking About

Verdict: YES, the sound is legitimately good straight out of the box.

The ZH870 keyboard’s factory-lubed linear switches (typically Gateron Brown or optional Sakura switches) deliver a muted “thocky” sound that’s satisfying without being loud enough to annoy coworkers. The gasket mount and foam dampening contribute to a deeper, less pingy sound signature compared to tray-mount keyboards.

User feedback from Amazon (4.7/5 stars, 77 reviews):

• “The sound is incredible straight out of the box — that creamy thock everyone talks about is real.”
• “Creamy, crisp feedback that feels premium.”

However, enthusiasts note a caveat: The “mushy” feel from the gasket mount won’t appeal to competitive gamers who prefer stiffer, more responsive boards like the Corsair K63 or Corsair K65 series. One r/MechanicalKeyboards user explained: “It sounds great for content, but the soft bottom-out feels sluggish for fast-paced FPS games.”

Typing Comfort: Ergonomics & Fatigue

Pros:

✅ No finger fatigue reported even after extended 8+ hour typing sessions
✅ OEM-profile keycaps provide familiar, comfortable height
✅ Gasket mount reduces impact shock on fingers

Cons:

❌ Negative tilt quirk: Some units have a -5° backward angle that feels “upside down” to users accustomed to forward-sloping keyboards
❌ Side-printed legends can be hard to read in certain lighting without RGB enabled

ZH870 Keyboard Aesthetics: Why It Went Viral

Keycap Designs That Define the Brand

The ZH870 keyboard’s IMD (In-Mold Decoration) PBT keycaps are its standout feature. Unlike standard ABS caps that develop shine within months, these PBT caps resist oil buildup and maintain clarity even after heavy use.

Popular ZH870 Keyboard Spider and Aesthetic Variants

1. Topographic (Midnight Sun): Black keycaps with white topographic map lines
2. ZH870 Keyboard Spider Web: Intricate web patterns with glow-through legends
3. ZH870 Keyboard Spiderweb Edition: Same as spider web with enhanced underglow
4. Starry Night: Gradient dye-sublimation with constellation motifs
5. Prism Edition: Multi-color gradient with side-glow RGB emphasis

Why it matters for content creators: These keycaps look stunning in setup photos and videos, which explains the ZH870 keyboard’s viral TikTok success. Multiple users confirmed: “I bought it for the aesthetic, stayed for the sound.”

Alt text: Four ZH870 keycap variants side by side – topographic, spider web, starry night, and prism designs

ZH870 RGB Lighting: Beautiful but Flawed

22 preset modes include wave, reactive, spectrum cycle, and breathing effects. The south-facing LEDs ensure keycap legends glow clearly without interference, while side-glow strips create an impressive underglow effect.

The problem: Multiple Amazon reviewers report non-configurable underglow stuck on rainbow mode, and some units have ESC key LEDs stuck on blue/green. The RGB customization software (Bootmapper) is difficult to find and poorly documented.

Bottom line: RGB looks great in low light but lacks the full customization of QMK/VIA-compatible boards.

For better RGB control, check our Logitech G213 RGB gaming keyboard or Corsair K55 RGB membrane reviews.

ZH870 Connectivity: Tri-Mode Performance Tested

2.4GHz Wireless: Gaming Performance

Latency: User reports indicate near-zero latency in 2.4GHz mode for casual gaming. However, no independent lab testing exists to confirm polling rates or input lag measurements.

Range: Reliable up to 10 meters (33 feet) in open space; walls and interference reduce this to ~5 meters.

Gaming verdict: Adequate for casual FPS/MOBA but lacks Hall effect switches and rapid trigger for competitive esports.

For wireless gaming keyboards, compare the Corsair K63 wireless TKL or Logitech K800 wireless.

Bluetooth 5.0: Multi-Device Productivity

Supports up to 5 devices with quick switching via Fn + 1/2/3/4/5. Pairing is straightforward, and macOS automatically detects keyboard layout (Command/Option keys work correctly without remapping).

Switching delay: 2-3 seconds to swap devices, which interrupts active typing — annoying for users who frequently switch between laptop and desktop.

USB-C Wired: Zero Latency

Plug-and-play with instant recognition on Windows, macOS, and PS5. The 1.8m braided cable is long enough for most desk setups but not detachable.

ZH870 Hot-Swap Switches: Customization Freedom

Stock Switch Options

Gateron Brown (Standard):

• Type: Tactile
• Actuation: 1.8mm | Total travel: 4mm
• Feel: Light tactile bump, quiet enough for office use
• Best for: Hybrid typing/gaming

Gateron Yellow (Optional):

• Type: Linear
• Feel: Smooth, no tactile bump, “buttery” keystrokes
• Best for: Pure typists who want silent operation

Sakura/Sea Sand (Marketing Names):

• Proprietary switches with undisclosed manufacturer
• Marketed as “silent” but users report a “ceramic-like click” — dampened, not truly silent

Modding Potential

Compatible with all 3-pin and 5-pin switches:

• Cherry MX (Red, Brown, Blue, Black)
• Gateron (Milky, Ink, Oil King)
• Kailh (Box, Speed, Pro)
• Custom linears (Alpaca, Banana Split, Tangerine)

No soldering required — simply pull stock switches with the included tool and snap in replacements. This makes the ZH870 keyboard an excellent beginner board for experimenting with different switch types.

ZH870 Keyboard Battery Life & Common Battery Problems

Advertised: 4000mAh Capacity

Zornher claims the 4000mAh battery provides weeks of wireless use with RGB disabled and several days with moderate RGB usage.

Reality: Inconsistent Performance

Amazon reviews reveal a pattern of battery issues:

• “Drains quickly despite showing full charge — requires constant plugging” (7% of 1-star reviews)
• “Battery wouldn’t charge properly, got a dud unit” (isolated QC failures)
• “Lasts 3-4 days with RGB on, about 1 week with RGB off” (positive experiences)

Charging indicator:

• Blue light (solid): Charging
• Green light: Fully charged
• Red flashing (ESC key): Low battery warning

Verdict: Battery performance varies by unit. Some users report excellent endurance, while others experience rapid drain. This inconsistency suggests QC issues that should be reported within the return window.

Zornher ZH870 Keyboard Software, Drivers & RGB Issues

The Problem: Hard to Find, Poorly Documented

Unlike established brands (Logitech, Razer, Corsair) with robust software ecosystems, Zornher provides minimal driver support. Users report:

❌ No clear download link on the official website
❌ Confusion between “Zornher software” and generic “Bootmapper” tools
❌ Limited functionality (basic RGB control, macro recording)
❌ No VIA/QMK support for advanced customization

Workaround: Reddit users suggest searching “Zornher driver ZH870” + model number to find third-party mirrors, but this raises security concerns.

Who this matters for:

• ❌ Power users needing per-key RGB, layers, or complex macros
• ✅ Casual users satisfied with preset RGB modes and standard key mappings

ZH870 Gaming Performance: Casual Yes, Competitive No

What the ZH870 Keyboard Does Well

✅ Low latency in 2.4GHz mode — responsive enough for League, Valorant, Fortnite at casual ranks
✅ Hot-swap allows gaming switch upgrades (install Kailh Speed Silver for faster actuation)
✅ Stable wireless connection — no disconnects or stuttering reported

Where It Falls Short

❌ No Hall effect switches — can’t achieve 0.1mm actuation for competitive advantage
❌ No rapid trigger — lacks dynamic key reset for faster inputs
❌ Gasket mount feels “mushy” — competitive players prefer stiffer platforms for precise control

Reddit consensus: “Most ‘gaming’ keyboards are a scam. The ZH870 is just fine for gaming unless you’re a professional esports player.”

Gaming keyboard alternatives: Compare with the Logitech G213 membrane keyboard, Corsair K55 RGB, Corsair K65 compact mechanical, or Corsair K100 flagship for different gaming options.

Is the Zornher ZH870 Keyboard Legit or a Scam?

Reddit’s Investigation

When the ZH870 first went viral in early 2024, r/keyboards and r/MechanicalKeyboards erupted with skepticism:

• “Have you ever heard of this keyboard?”
• “No reviews anywhere — is this a dropshipping scam?”
• “Looks exactly like the Aula F99 Pro”

The Verdict: Legitimate Seller, Likely Rebrand

Evidence for legitimacy:

✅ Multiple confirmed deliveries across Reddit, Amazon, regional resellers
✅ 2-year warranty offered on official site
✅ Responsive customer service (refunds for defective units)
✅ No widespread reports of non-delivery or fraud

Evidence for rebrand concerns:

⚠️ Strong visual and spec resemblance to Aula F99 Pro
⚠️ Limited company history and vague manufacturing details
⚠️ Heavy TikTok influencer marketing with few independent reviews
⚠️ Price premium ($90 vs. $60 for Aula F99 Pro on AliExpress)

Bottom line: Zornher is not a scam — you will receive a functional ZH870 keyboard. However, you’re likely buying a white-labeled Chinese OEM board with custom keycaps and marketing, not an original design.

5-Star (Updated): Battery Issue → Excellent Customer Service — Ethan Silva (September 2025)

“The keyboard works technically and looks pretty dang cool. It is bright and feels good to type it. The quality of the board feels topnotch. But I have one huge glaring issue: It does not hold a charge at all. I’ll plug it in to the PC and the software says it is 100% charged but as soon as you unplug it, it will drop to 5%… I purchased two of these boards and one of them does not have this problem at all, which leads me to believe it is a quality issue.”

UPDATE:

“ZORNHER Troubleshot the faulty board with me diligently for a day or two before coming to the same conclusion I did; The battery was a dud. They offered me a full refund. Fantastic customer service. The other board is working great and has some serious style. Just make sure to know your homekeys!”

The Bottom Line

At $90-100, the Zornher ZH870 keyboard delivers on its viral promises: gorgeous keycaps, satisfying sound, and versatile connectivity in a beginner-friendly package. At $130+, you’re paying a TikTok tax for a likely Aula F99 Pro rebrand with questionable long-term reliability.

• Sound: 9/10 (legitimately creamy)
• Aesthetics: 10/10 (viral for a reason)
• Build Quality: 6/10 (plastic feels cheap)
• Value at $90: 9/10 (excellent)
• Value at $135: 4/10 (overpriced)
• Software: 3/10 (poor documentation)
• Reliability: 6/10 (battery QC issues)

Our recommendation: Wait for sales to hit $90-100, buy from Amazon for easy returns, and test the battery immediately. If you want guaranteed quality, spend $20 more on the ND75 or stick with Keychron’s K-series.
