I grabbed the G403 a while back because I prefer wired mice. Same exact design and feel as this one though, and it's the best mouse I've ever owned. Very smooth, and feels great with the adjustable weight inside it. The RGB is… neat I guess? I don't do custom stuff with the RGB at all because that doesn't interest me.
