⚡ Real-World Performance Analysis

Switch Type
Mechanical (Hot-swappable)
The switch type defines every keystroke's feel, sound, and actuation feedback. The right choice depends on whether you prefer silence (linear/membrane), tactile feedback (tactile), or audible confirmation (clicky).
Polling Rate
High polling rate modes
Standard polling — fine for typing and office work. Not optimised for gaming where keystroke timing precision matters.

📐 Layout Guide — Is This the Right Size For You?

100%

Full-size keyboard with numpad. Best for data entry, spreadsheets, and accounting. Widest footprint — pushes your mouse further right, which can strain your shoulder over long sessions.

96%

Compact full layout — all keys including numpad, slightly tighter spacing. Good compromise: keeps numpad access while saving ~2cm of desk width.

← This keyboard
TKL

No numpad. ~80% of a full board. The most popular gaming layout — frees up space for a larger mousepad and keeps your mouse arm at a natural angle.

75%

Compact with function row and most navigation keys retained. Excellent travel keyboard. Arrow keys are dedicated but other nav keys may be layered.

65%

No function row but keeps dedicated arrow keys. Very popular for minimalist setups. Most daily-use keys accessible without layers.

60%

Alphanumeric block only. Most compact. Function keys, arrows, and nav accessed via Fn layers. High learning curve but ultimate portability.

40%

Extreme minimalism — letters and modifiers only. Almost everything on layers. For enthusiasts only; not practical as a primary keyboard without extensive adjustment.

🔩 Switch & Build Quality — What You're Actually Getting

Switch Mechanical (Hot-swappable) Sound profile: Standard noise level for mechanical switches.
Hot-Swap No Switches are soldered. Choose your preferred switch type carefully before buying — you can't easily change them later. If you're unsure between switch types, consider a hot-swap keyboard so you can experiment.
Weight Not specified Lightweight keyboard — easy to move, good for travel. May shift on the desk without a good rubber base. Check that the feet grip properly.

🎮 Gaming Use Cases — How Does It Perform?

🎯FPS (CS2, Valorant, Apex Legends)
Good

Adequate for casual to mid-level FPS gaming. Not optimised for top competitive play but perfectly playable.

📝Typing, Coding & Productivity
Good

Suitable for productivity typing. Check if the layout includes function keys and navigation clusters your workflow relies on.

🗺️MOBA / RTS (LoL, StarCraft)
Good

MOBA and RTS games demand rapid, precise key combinations. Standard polling is adequate for ability timing at casual to mid levels.

🎙️Streaming & Content Creation
Good

Streamers need reliable hotkeys for OBS scene switches, mute toggles, and clip marking. Switch noise is unlikely to cause issues in voice recording.

✈️Multi-Device & Travel
Excellent

Wired keyboards travel fine but the cable limits flexibility.

💡 Practical Buying Advice

The ATTACK SHARK X820 ULTRA – Full Specification is a Mainstream Mechanical keyboard from attack-shark. As a mechanical keyboard, it delivers a noticeably different feel from membrane boards — more tactile, more durable, and more customisable.

⌨️ Keycaps matter too: Check whether the keycaps are ABS or PBT. PBT keycaps resist shine (the greasy, worn look) much better than ABS. If this keyboard ships with ABS keycaps, budget for a PBT keycap set replacement after 6–12 months of heavy use if aesthetics matter to you.
