Asus's ROG 20th anniversary edition gear is pretty much all about extravagance. Just look at the $600 Azoth Extreme Edition 20. The Harpe II Extreme Edition 20 is much the same, with gold plating and a whopping 65,000 DPI. It is bougie in feel, look, and price.
I couldn't possibly call it a bad gaming mouse, because taste aside, it's a bit of a beast. It's just not a feasible buy for someone only looking for a competitive-level gaming mouse, and that's before mentioning the weight increase that comes with shoving gold inside it.
