I’d suggest looking at hollow wall anchors (also called umbrellas fixings) which are similar in design to the ones you’re describing but heavier duty (steel) and designed to hold the weight of a radiator, though they can be difficult to use if you’re just using a screwdriver (in my limited experience.) Also a new product called Gripit which I have no experience with but apparently are designed for this sort of thing. Seems quite a bit easier to use.
If it’s something that people are using a lot then anything that improves the experience can be seen as increasingly important/valuable.
From a practicality perspective, they offer precision, feedback and speed advantages over membrane/rubber dome types which can be valuable in different use cases.
I haven’t used gamer brand mechanical keyboards in a while, but my previous impression was that they were overpriced and generally at the lower quality/poorer experience end of the spectrum. I think there are likely far better options out there at all price points.
