Logitech G502, the exact model doesn’t matter as there are a few of them. Not sure they have many differences, some might be older. The one I am currently using is the G502 Hero, and I have a G502 proteus core as a backup. The hero is RGB if you’re into that, the proteus core is Logitech standard blue LED. Both have customizable weight. 10/10 recommend these mice, I think most people will say the same
