It's a wireless mouse and pretty old, but the Logitech Anywhere MX. Been using mine since 2012 and still going strong, good battery life, good build quality, and I know it's not for gaming, but it just works. (And you can use it with one or 2 batteries for different weight if you want)
edit: i know there's an Anywhere MX 2 but it's rechargeable and not heavy enough for my taste. Also i think it's bluetooth, so inevitable latency issues.
