Business Transparency: How we operate?
As a small UK business, we handle every order ourselves — no drop shipping involved. Every item we send out goes through a quality control check to make sure you receive exactly what you ordered and in the condition you’d expect.
Some of our products are sourced from local UK suppliers, while others come directly from manufacturers we trust. The dispatch times for each item are clearly shown on the product listing, so you’ll always know whether it’s available for same-day dispatch or if it needs a little extra time before shipping.
We also pride ourselves on providing the best customer support possible. When you contact us, you’ll always be speaking directly to one of the three people who run this business — no automated bots, no outsourced call centres, just real help from people who know and love the products we sell.

Built to last with industry-leading reliability. Each switch is rated for 50 million keystrokes, ensuring years of consistent performance whether you're gaming, coding, or typing all day.
Key Features & Benefits
All-PC Construction
Full polycarbonate housing and stem provide superior clarity in RGB lighting, consistent sound profile, and enhanced durability. PC material offers excellent smoothness and a clean, crisp typing experience.
Factory Lubrication
Pre-lubed from the factory for instant premium performance. Save time and enjoy buttery-smooth keystrokes right out of the box—no manual lubing required.
Gold-Plated Springs
Premium 20mm gold-plated springs resist corrosion and ensure consistent spring weight throughout the switch's lifespan. Longer springs provide smoother return action and reduce spring ping.
Linear Performance
Smooth, consistent keystrokes with no tactile bump or click. Perfect for gaming where rapid actuation is crucial, or for typing enthusiasts who prefer a fluid, uninterrupted keystroke.
Multiple Weight Options
Choose from 37g (ultra-light), 55g (medium), or 62g (medium-heavy) to match your typing preference. Lighter weights reduce finger fatigue, while heavier weights provide more deliberate control.
5-Pin PCB Mount
Full 5-pin design ensures stable mounting and reduces wobble. Compatible with both hot-swap sockets and traditional solder PCBs. Simply clip the extra pins for 3-pin plate-mount keyboards.
Recommended Use Cases
37g - Ultra-Light: Ideal for speed typists, those with lighter key press preferences, or users looking to reduce finger fatigue during extended typing sessions. Extremely fast actuation for competitive gaming.
55g - Medium: The versatile all-rounder perfect for both gaming and typing. Balanced weight provides good tactile feedback without being too heavy or too light. Great for first-time linear switch users.
62g - Medium-Heavy: Best for deliberate typists who want more resistance and control. Reduces accidental key presses and provides a more substantial feel. Excellent for precision gaming and professional typing work.
