When keyboard inputs fail to register because too many keys were pressed simultaneously.

N-Key Rollover. You can press ALL keys at once and the PC registers every single one. Mandatory for gamers.

How to find a broken key?

Open our Keyboard Tester. Press the suspect key. If it doesn't light up green, the switch or circuit is dead.

Membrane vs. Mechanical?

Membrane uses rubber (cheap, mushy). Mechanical uses springs/switches (precise, durable).

How to remove a keycap?

Use a Keycap Puller tool. Do not pry with a knife, you might break the switch stem.

What are Optical Switches?

They use light beams instead of metal contact to activate. Theoretically faster and more durable.

Why does my spacebar rattle?

The stabilizers (metal bars) are dry. Applying a little dielectric grease (Lube) fixes the rattle.

How to Increase Your CPS (Clicks Per Second)

High CPS isn't just about speed; it's about technique. Relax your forearm to prevent fatigue. Use a gaming mouse with high-quality switches (like Omron or Optical). Practice for 10 minutes daily to build muscle memory.

Jitter Clicking vs. Butterfly Clicking

**Jitter Clicking** involves vibrating your arm muscles to achieve 12-14 CPS, offering steady aim. **Butterfly Clicking** uses two fingers alternating on one button to hit 20+ CPS, essential for 'Bridging' in Minecraft Bedwars. Note: Butterfly requires a mouse that supports double clicking (low debounce time).

What is the CPS World Record?

The legitimate record for the 10-second test is around 22-24 CPS. However, using the **Drag Click** technique, some players can achieve burst speeds of over 30 CPS in a single second.

Why does Click Speed matter in Gaming?

In Minecraft 1.8 PvP, high CPS reduces the 'Knockback' you take and helps start combos. In FPS games like Valorant or CS2, fast clicking helps with tap-firing semi-automatic weapons accurately.

Is your mouse Double Clicking randomly?

If you click once but the PC registers two clicks, your mouse switch is faulty (Double Click Issue). Use our 'Mouse Test' tool to diagnose this hardware failure before buying a new mouse.
