he Logitech G305 LIGHTSPEED is a wireless gaming mouse with a solid, plastic shell. It connects using a USB receiver and uses a single AA battery for power. Its egg-shaped body is nearly symmetrical, and there's a pair of side buttons on the left and a button behind the scroll wheel that acts as a CPI button by default. This mouse is a bit on the smaller side and may not be well-suited for people with very large hands, but it feels as well-built and premium as some of Logitech's higher-end mice. Performance-wise, it has impressively low click latency and a very low minimum lift-off distance. You can also adjust the CPI by precise increments within a broad range.

Our Verdict
8.4 Video Games (FPS)
The Logitech G305 LIGHTSPEED is a good mouse for FPS gaming. It has great click latency and a comfortable shape that's well-suited for most hand sizes and grip types. All its six buttons are programmable, and its sensor performance is excellent. Due to its small size, it isn't an ideal choice for larger hands. Also, it's heavy compared to many gaming mice on the market, and aside from custom modifications, there aren't any weight optimization options.

PROS
Feels very well-built.
Great click latency.
CONS
Heavy.
