He likes the grip, the backlit logo which complements his keyboard and he likes the adjustable scrolling.

I was worried that the adjustable scroll wheel would make it feel cheap or rattle but fortunately, it doesn't

Great responsiveness, good weight and balance, smooth scrolling, RGB lighting but reserved and professional looking, good customization without being way over the top.

I had a Logitech MX Master, and compared to that:+adjustable DPI, on the mouse, via a rocker button, that's pretty handy actually+'clutch' to release that DPI setting, so the mouse goes nice and slow for detailed work- the Logitech has a nice free spinning wheel for fast scrolling up and down a browser page.- Logitech has slightly better ergonomics for my big hand
