The EVGA X20 is a decent FPS gaming mouse, but it's very heavy, and while its click latency is good, some gamers may prefer a more responsive-feeling option. That said, it feels well-built and has a comfortable, right-handed shape suitable for most hand sizes and all grip types. You can precisely adjust the CPI by increments of 50 within a broad range, and it has a fairly low minimum lift-off distance. However, you can't adjust it as low as EVGA advertises, and it's higher than many other mid-range FPS gaming mice.
