The Logitech G MX518 Legendary mouse is a revived version of the original Logitech G MX518, which was released in 2005. The 2019 version is good for gaming thanks to its wide and adjustable CPI range, as well as its remarkably low click latency. All of its buttons can be remapped in the Logitech G HUB software, and you can even set a G-Shift button to give you a second layer of controls. It's comfortable to use, but since it's quite long, people with small hands may not be able to use it comfortably with any grip type. Sadly, most of its parts feel cheaply made, and some of its buttons have different pre-travel distances than the rest, which feels very weird. Overall, it's a good gaming mouse for its price.
Our Verdict
The Logitech G MX518 is okay for office use. The scroll wheel can't be unlocked for infinite scrolling, but it's comfortable to use. However, people with small hands may struggle to reach the buttons with any grip type. It's decently built, although some parts of it feel cheap. However, it has many programmable inputs and it's fully compatible with Windows and macOS.
- All buttons are programmable.
- Fully compatible with Windows and macOS.
- Large size may not be ideal for small hands.
- No infinite scroll.
The Logitech G MX518 is good for FPS gaming. It has a remarkably low click latency, a wide CPI range with very little variation, and a high polling rate. Its feet glide well on a mousepad and directly on a desk, but sadly the cable isn't very flexible and it retains kinks. Also, it's fairly heavy for its size, and some parts of it feel cheaply made.
- Remarkably low click latency.
- All buttons are programmable.
- Large size may not be ideal for small hands.
The Logitech G MX518 is good for MMO gaming. It's comfortable to use, although people with small hands may not be able to use it comfortably with any grip type. It has a remarkably low click latency and an adjustable CPI range. You can program all of the buttons, and you can even set a G-Shift button to give you a second layer of customization. Unfortunately, it only has two side buttons, which isn't as much as dedicated MMO mice have.
- Remarkably low click latency.
- All buttons are programmable.
- Fully compatible with Windows and macOS.
- Only two side buttons.
- Large size may not be ideal for small hands.
The Logitech G MX518 is a decent ultra-light gaming mouse. It's fairly heavy for its size and its rubber cable retains kinks from the packaging. It's also too long for small hands to reach all the buttons comfortably. On the upside, it has a remarkably low click latency, and its feet glide well on both a mousepad and directly on a desk.
- Remarkably low click latency.
- All buttons are programmable.
- Heavy for its size.
- Large size may not be ideal for small hands.
The Logitech G MX518 isn't designed for travel. It's a wired gaming mouse that is best suited for an at-home gaming setup. Its non-removable wire and heaviness don't make it very portable.
- Fully compatible with Windows and macOS.
- Heavy for its size.
- Large size may not be ideal for small hands.

Popular Mouse Comparisons
The Logitech MX518 Legendary is a good and affordable gaming mouse, but it doesn't rival other options in its price range. Most parts of it feel cheaply made, the scroll wheel has uneven steps, and the buttons have different pre-travel distances, which is off-putting. For other options, see our recommendations for the best mice and the best wireless mice. If you're interested in Logitech products, also check out the best Logitech mice.
The Logitech G MX518 Legendary and the Logitech G5 have the same shape and size. The MX518 Legendary is a refresh of the original MX518 with an improved sensor, so unsurprisingly, its CPI range is much wider than the G5. It also has a lower lift-off distance, a more consistent sensor, onboard memory, and an extra side button.
The Logitech G502 HERO is better than the Logitech G MX518 Legendary. The G502 HERO feels better built and more comfortable for most people. Also, it has a lower lift-off distance and many more programmable buttons. However, the MX518 Legendary's feet glide better, and its sensor is slightly more consistent than the G502 HERO.
The Razer Viper Mini is better than the Logitech G MX518 Legendary. The Razer feels better built, and its feet glide better. However, the Logitech has a better sensor and a wider CPI range that can adjust more precisely, and since it's a larger mouse, it should be more comfortable than the Razer for larger-sized hands.
The Logitech G MX518 Legendary is better than the Corsair M55 RGB Pro. The Logitech has more programmable buttons thanks to its G-Shift button, a wider and more precisely adjustable CPI range, and its sensor is much more consistent. However, the Corsair feels better built and has RGB lighting.
