Business Transparency: How we operate?

As a small UK business, we handle every order ourselves — no dropshipping. We curate what we sell, pack orders with care, and stand behind everything we ship, so you receive exactly what you ordered and in the condition you’d expect.

To spread our logistics across two continents, we hold our best sellers in stock in both the UK and our warehouse abroad, managed by our co-owner Russel in Hong Kong. Less common products are sourced on demand from suppliers we trust, which keeps prices fair without warehousing slow-moving stock. Your order ships from wherever it’s in stock and closest to you — so the dispatch time shown on each product listing tells you whether it’s ready for same-day dispatch or 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.

Keychron Z11 Ultra: 65% Split Alice Wireless Mechanical Keyboard, Dual 8K

An arcade cabinet, cut in half

The Keychron Z11 Ultra looks like it was pulled from a 1970s arcade floor: a CNC-machined aluminium chassis with the chunky proportions of a cabinet control panel, and a cassette-style metal cartridge in the lower left corner that slides out to reveal the 2.4 GHz receiver. It is a keyboard with a face, in a category that mostly ships in black rectangles.

Then it splits. The 65% layout is cut into two angled Alice halves, each with its own 4000 mAh battery and its own 8000 Hz wireless link to the receiver, which is the "dual 8K" in the name. Put the halves where your shoulders want them, a mouse pad's width apart or tight together, and your wrists stop twisting inward to meet a straight row of keys.

Built to be quiet and fast at the same time

Gasket mount, six layers of foam

The plate floats on gaskets inside the aluminium case, with six dampening layers, a single-key slotted PCB and a PP plate underneath. Keystrokes land soft and round rather than ringing off the metal, which is the difference between a board you tolerate in an open office and one you forget is there.

8000 Hz on cable and 2.4 GHz

Both halves report to the receiver 8000 times a second, wireless or wired, so the split costs you nothing in responsiveness. Keychron runs it on ZMK, a low-power firmware built for wireless boards, so the high polling rate does not drain the batteries the way it would on a conventional stack.

Tri-mode, dual batteries

USB-C, 2.4 GHz through the stored receiver, or Bluetooth for a laptop or tablet. A 4000 mAh cell in each half means weeks between charges in normal use, and the two halves charge independently.

Finished like a custom, priced like a Keychron

The caps are double-shot PBT in Cherry profile, the legends moulded through the plastic so they never wear, and the switches are a custom HUANUO set tuned for the gasket build. An X-shaped silicone pad on the underside of each half grips the desk and stops case vibration reaching it, so the board stays put even when the two halves sit at odd angles.

Because it is Alice rather than a full ortholinear or column-staggered split, the learning curve is short. The keys are where your fingers expect them; only the two halves have moved. Most people are back to full speed within a day or two, and the reduced wrist angle is something you notice by the end of the first week.

Q&A & Specifications

Questions & Answers

How do the two halves talk to each other?

Wirelessly, each on its own 8000 Hz link to the receiver stored in the left half. There is no cable between the halves, so you can place them freely.

Can I remap keys?

Yes. The Z11 Ultra runs ZMK firmware with Keychron's online configurator, so layers, macros and key assignments are set in the browser.

Does 8000 Hz matter for office use?

Not for typing. It matters in games, where it cuts the delay between a key press and the PC seeing it. For everyday work you can leave it at a lower rate and gain battery life.
