Keychron has been steadily updating its mechanical keyboard line-up with ZMK firmware and its new Silk POM mechanical switches. One of the more recent updates is the Keychron P6 Ultra, which features a full-size layout, 8 kHz polling, and an understated design with a neat party trick. The hallmark feature of the P6 Ultra is its quick-disassembly ball-catch closure mechanism, which allows for toolless disassembly of the aluminium case. This is becoming more common in mechanical keyboards, because it allows you to more easily get at the internals for modifications, although it does introduce a drawback in that it makes the front height slightly taller—the P2 Ultra measures in at 22.25 mm as a result. Aside from the quick-release closure, the P6 Ultra also features a programmable knob, and the entire keyboard is customizable and programmable in Keychron Launcher, the brand's VIA-like web driver.

The P6 Ultra is available on Keychron's online store for $199.99 and on Amazon for $179.99, and it can be purchased with the Silk POM Red (linear), Brown (tactile), and Banana (early-bump tactile) switches. It is only available in black, and it comes with black Cherry profile double-shot PBT keycaps with gray and orange accent keys. Keychron says the 4,000 mAh battery in the P6 Ultra is capable of keeping it going for 660 hours on a single charge, at least without the backlighting disabled. With the backlighting on its lowest brightness, that drops to 200 hours per Keychron. It features both 2.4 GHz and Bluetooth 5.3 connectivity for convenience and broad compatibility. Unlike many of Keychron's other mechanical keyboards, this seems to be based on a design similar to that of the Lemokey P2 HE, which also features the same silicone bean gasket mount and quick-disassembly feature.
