It worked excellently with this repository and some help from Claude Code; a GPT chat might have been useful as well.

Good delivery
Good seller
The product is excellent and works well.
It's quite useful, and for the price I think it's very good; it's a RED switch mechanic.
It has RGB and I think it can be programmed.
The key configuration is quite simple and only needs to be done once. The lights are off by default; if you want to activate them, you can do it in the same software as the keys. The knob is quite useful and in general it's good for shortcuts or something like that. I bought it for Osu! And if you buy it to play, it's very useful, especially for rhythm games, and if you're used to playing with the keys of a notebook, you could feel comfortable with it. The switches are interchangeable, so it's not disposable, but if you want a top-of-the-line one, you should probably look for a higher-end model, although this one serves its purpose well and is quite good for the price.
Delivery one day early, products are as expected although I thought I could do more with them; the actions remain very limited.
