Getting the right mouse can make a big difference to your experience. The best gaming mouse for you will be designed for the things you do & the games you play, suit the way you hold it and be at a size that feels comfortable.
If you're not gaming, it's very unlikely you'll need a high-precision laser mouse, so you can keep costs down and shop for an option that fits your chosen aesthetic.
For years there were strong arguments against buying a wireless gaming mouse, but latency is no longer really an issue where good quality mice are concerned, so the most significant difference now is cost and aesthetic. if you're willing to pay extra for a cable-free desktop and don't mind the hassle batteries bring, a wireless mouse is a great option.
If you want a very lightweight mouse then stick to wired. a battery will add a surprising amount of extra weight to your mouse.
