Op18k low user count?

Just curious why only maybe 1-2 pro players across multiple games use this mouse? I thought it would be way more popular? It's accessible, cheap, solid QC, flawless performance, shape is great? Not that it matters as I really like it myself, more just curious why more professional players aren't using it? The aim/mouse community seems to love it but outside of that I see nothing.

I also don't think it's just the wire, I believe the case seems to be the same for the op1w 4k too.
