something mouse reviewers never talk about is the software.
sure you can say razer makes the best mice, but then you have to deal with synapse.
logitech is the best for gaming mouse in the software department, at least of the big mouse makers, since you can actually close logitech's software and it won't run in the background unless you want it to.
do not buy corsair or razer mice because they all have really garbage software, and some of the cheaper mice require software to change literally anything.
