Design and Build Quality

The AK820 Pro surprises immediately with its weight — the CNC aluminum plate gives it a substantial feel that you’d expect from keyboards costing ¥400+. The top plate is a single piece of CNC-machined aluminum (choice of silver, black, blue, or pink) with a plastic bottom housing.

The signature feature is the 0.85-inch TFT LCD screen in the top right corner, next to the volume knob. The screen can display:

• System clock
• CPU/GPU usage (via software)
• Custom images/GIFs (via software)
• Keyboard status (caps lock, battery, connection mode)

The knob is aluminum with tactile rotation steps. It controls volume by default but can be customized.

“The aluminum build feels like a ¥500 keyboard. I was shocked when I unboxed it — the weight, the anodized finish, the satisfying sound of the gasket mount. The screen is small but fun — I put a pixel art cat on mine.” — JD.com user

Typing Experience

The gasket mount with silicone dampening gives the AK820 Pro a soft, bouncy typing feel with a deep “thock” sound profile. This is significantly better than the tray-mount Keychron V series at ¥100 more.

The stock switches are Ajazz’s own Peach (linear, pre-lubed) or Mango (tactile). They come factory-lubed with decent consistency — smoother than Outemu, not quite as refined as Gateron Oil Kings but impressive for the price.

The stabilizers are plate-mounted and pre-lubed. Spacebar rattle is minimal — far better than the RK61 or budget VGN boards from a year ago.

“The gasket mount makes a huge difference. Typing on this feels bouncy and comfortable — way better than my old tray-mount keyboard. The Peach switches are smooth enough that I don’t feel the need to swap them. Best feeling keyboard I’ve used under ¥300.” — JD.com user

User Reviews by Theme

The LCD Screen — Novelty or Useful?

“The screen is fun to play with — I put a looping GIF of my cat on it. But honestly I barely look at it while typing. The volume knob is more useful day-to-day. It’s a conversation starter but not a productivity tool.” — JD.com user

💡 Summary: The LCD screen is entertaining and unique but adds limited practical value day-to-day.

Aluminum Build Quality

“I’ve had this keyboard for 4 months and it still looks brand new. The aluminum top plate doesn’t show fingerprints or smudges. It’s heavy enough that it never slides on my desk. The build quality is genuinely impressive.” — JD.com user

💡 Summary: CNC aluminum build far exceeds expectations at this price — feels like a ¥400-500 keyboard.

Software Limitations

“The Ajazz driver software is usable on Windows but doesn’t exist for Mac. You need Windows to set up custom screen content or macros. Once configured, settings save to onboard memory, so Mac users can set it up once on Windows and use it normally.” — JD.com user

💡 Summary: Windows-only software is a limitation for Mac users, though settings save to onboard memory.

Bluetooth Stability

“Bluetooth works well with my MacBook — maybe one disconnection per week. Reconnects automatically in about 3 seconds. The 2.4GHz dongle is flawless with zero latency for gaming. I keep it in wired mode at my desk.” — JD.com user

💡 Summary: 2.4GHz dongle is perfect for gaming; Bluetooth is good enough for casual use.

Switch Quality

“The Peach linear switches are factory-lubed but a bit inconsistent — some keys have a slight scratchy feel. I replaced them with Gateron Milky Yellows and the keyboard sounds even better. Glad it supports 5-pin hot-swap.” — JD.com user

💡 Summary: Stock switches are good but not great — being hot-swappable lets users upgrade easily.

Purchase Recommendations

FAQ

Q: Does the Ajazz AK820 Pro work with Mac? A: Yes. The keyboard works with macOS in Bluetooth and wired modes. The 2.4GHz dongle also works on Mac. However, the companion software is Windows-only — you need a Windows PC to configure the LCD screen and macros.

Q: Can I customize the LCD screen? A: Yes, using the Ajazz driver software on Windows. You can display the system clock, CPU/GPU stats, or upload custom images/GIFs (size limited to 128×32 pixels). Settings save to the keyboard’s onboard memory.

Q: Is the AK820 Pro good for gaming? A: Yes. Use the 2.4GHz dongle or wired connection for low-latency gaming. The gasket mount provides comfortable long-session typing. The Peach linear switches are smooth enough for FPS and MOBA games.

Q: How does the AK820 Pro compare to the regular AK820? A: The AK820 Pro adds the LCD screen (regular AK820 has a LED indicator panel), a CNC aluminum top plate (plastic on regular), and a volume knob. The Pro is worth the ¥30-40 premium.

Q: What switches come with the AK820 Pro? A: Two options: Peach (linear, 45g actuation, factory-lubed) and Mango (tactile, 50g bump). Both are Ajazz’s own branded switches. The hot-swap sockets support any 3-pin or 5-pin MX-compatible switch.
