The 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
While the Logitech G305 is designed primarily as a gaming mouse, it's decent for office use. It feels very well-built and solid, but it's somewhat heavy for its size. It has two side buttons, and all buttons are programmable using the customization software compatible with Windows and macOS. However, if you have extra large-sized hands, you may find it unwieldy, depending on your preferred grip type. Also, the scroll wheel lacks a free-scrolling mode and left/right tilt inputs, which are useful features for many workflows.
- Feels very well-built.
- Tons of customization options using the companion software for Windows or macOS.
- Connects wirelessly with its USB receiver.
- Might be a bit too small for people with larger hands.
- Scroll wheel lacks L/R tilt buttons and a free-scrolling mode.
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.
- Feels very well-built.
- Great click latency.
- Heavy.
The Logitech G305 is a decent mouse for MMO gaming. While it doesn't have as many side buttons as dedicated MMO mice, all its buttons are programmable, including the CPI button behind the scroll wheel. It also has great click latency and great sensor performance, with many customization options within Logitech's G HUB software. Unfortunately, it's a bit on the smaller side, and those with larger hands will likely only be comfortable using a claw or fingertip grip.
- Feels very well-built.
- Great click latency.
- Tons of customization options using the companion software for Windows or macOS.
- Might be a bit too small for people with larger hands.
- Heavy.
- Not nearly as many side buttons as a dedicated MMO mouse.

Differences Between Sizes And Variants
While we tested the white version, the Logitech G305 LIGHTSPEED is also available in black, lilac, and blue. There's also a variant that's part of a League of Legends collaboration lineup, with K/DA coloring. Outside of North America, this mouse is sometimes called the Logitech G304 LIGHTSYNC. As we understand it, the only difference is in name, and we expect our test results to remain applicable for this alternatively named variant.

The Logitech G309 LIGHTSPEED and the Logitech G305 LIGHTSPEED are wireless gaming mice with egg-like symmetrical shapes. They're both powered by a removable AA battery, but the G309 supports Logitech's POWERPLAY, meaning you can use it without a battery if you have a compatible mousepad. The G309 is lighter, has a newer sensor and optical switches, and supports Bluetooth.
The Logitech G502 HERO is a better gaming mouse than the Logitech G305 LIGHTSPEED. It feels better built, has more programmable buttons, and you can set the CPI more precisely. Its scroll wheel also has L/R tilt buttons and a free-scrolling mode. On the other hand, the G305 can be used with any grip type by people with smaller hands and is more portable thanks to its smaller, wireless design.
For most uses, the Logitech G703 LIGHTSPEED with HERO Sensor is better than the Logitech G305 LIGHTSPEED. The G703 is lighter, more comfortable to use, and has better performance due to its wider CPI range and lower CPI variation. Its build quality also feels better, and it has RGB lighting, which the G305 lacks. However, the G305 is smaller and more portable, and its ambidextrous shape makes it more suitable for left-handed use even though its side buttons are on the left side.
The Logitech G305 LIGHTSPEED and the Razer Orochi V2 are good wireless gaming mice with strengths in different areas. The Razer is significantly lighter, connects wirelessly with its USB receiver or via Bluetooth, and uses either an AA or AAA battery. It's well-suited for fingertip grip, but only for large and medium-sized hands. Comparatively, the Logitech only connects wirelessly with a USB receiver, and it uses one AA battery. That said, you can adjust its CPI more precisely, and its software is compatible with Windows and macOS. It's well-suited to all hand sizes with a fingertip grip.
