Epomaker x Aula F75 vs Keychron V1 Ultra 8K

The F75 is the board that made gasket mounting a budget feature. The plate floats on poron gaskets rather than being screwed to the case, and Aula stacks five dampening layers underneath, so the stock sound is the deep, muted profile enthusiasts spend money chasing instead of the hollow ping a cheap tray-mount board makes.

The switches arrive factory-lubed and the stabilisers are usually acceptable out of the box, which matters more than any spec on the listing: unlubed stabilisers rattle on the spacebar and enter key, and fixing them means pulling keycaps and applying grease. Sockets are hot-swap for 3-pin and 5-pin, and the board runs wired, over 2.4GHz and over Bluetooth.

What you give up is control and refinement. Configuration runs through Aula's own Windows software rather than VIA or QMK, so remapping on a Mac or Linux machine is awkward and the software will not outlive the product. The plastic case flexes if you pick the board up by one corner, and reviewers consistently single out the volume knob as loose and the small display as dim and easy to scratch. None of that reaches your fingers while you type.

The V1 Ultra 8K is the V1 8K with the one limitation removed. Same 75% gasket-mounted platform, same hot-swap sockets, same PBT caps, plus 2.4GHz and Bluetooth, and an 8000Hz polling rate that survives the wireless link rather than being a wired-only mode. TechRadar measured its battery claim as the headline feature and called the figure absurd, in the good sense.

The firmware changes with it. ZMK is the open wireless-first stack, so the layers and macros you configure are stored on the board and behave the same across operating systems, and there is no background application deciding whether your keyboard works today. If you have used VIA on a wired Keychron, the concepts carry across even though the tooling is different.

What you are paying for is the radio and the battery, not a better typing experience. Head to head with the wired V1 the sound and feel are the same, so if the board never leaves one desk the premium buys nothing. The switch to ZMK also means the QMK configuration files and community layouts written for the wired V1 do not transfer directly, which is a genuine annoyance if you already have a layout you like.
