Feels like HTX blew up out of nowhere with a ton of long form content at once, but they were huge in Chinese social media already, and finally decided to start translating previous content to english and uploading to Youtube.

I'd watch a video about the making of this video.

The sound is described like creamy or thocky.

You can get aula f75 for cheap, arround 50$, there are plenty of sound tests on youtube as it's very popular.

I got that version and I am happy, but if I was to buy a new one I would get the full size f108 because it's important for me to have distance between arrow keys and other keys. And tbh I would just get an apple keyboard or something similarly slim because it's more confortable for me. However for thicc keyboards, aula f75 has great specs and sound at a very good price.

I recently learned that it's not just the switch, but also the gasket, so the switch plate material, the foam layers and even the keycap itself. I built two different split keyboards recently with the same simple Kailh box red v2 switch and they sound and feel completely different just because of the thickness of the switch plate and the type of keycaps I use.(check this for example https://www.youtube.com/shorts/HIldaxljpzc )

You can check if you find the switches colors here(it looks like an Akko purple pro, but not quite) https://keeb-finder.com/switches

Whereas rtings has a filtering list that also has sound profiles in the review pages.

I imagine it's uncomfortable to grip since you need to be careful to not press a key doing so. Since you can't rely on fingers much for grip, you could put more force pressing downward with your wrist but that would also add friction with the table. Mice are small enough that you can fit your hand around it, but a keyboard is large and flat.

Put keyboard in perfect ergonomic position on the desk, move mouse, now the keyboard's in a terrible ergonomic position.

Also you have to keep a much bigger area clear for it.

I'm assuming it's too heavy and has too much contact surface (so more friction), making it too hard to glide smoothly.

There's probably something with the position of the hand when you move the mouse as well. At least I seem to be moving mostly the wrist when I use my mouse, meaning that my hand and forearm are not always aligned; without this alignment, I feel there's more strain on the wrist when typing.

I'd also guess fatigue. Pushing around that huge thing constantly

Same, looks like an amazing idea.
