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 casual gaming thanks to its wide and adjustable CPI range, as well as its decently 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.
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.
The Logitech G MX518 is good for FPS gaming. It has a decently 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.
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 decently 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.
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 decently low click latency and its feet glide well on both a mousepad and directly on a desk.
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.
The Logitech G MX518 (2019) is a revival of the original MX518 (2005). The revived version has the same curvy shape, with the same Logitech G logo at the back, but it has a different design on its top. The revived version has a smoother look with a glossy gradient that goes from light grey to black. The Legendary has two side buttons, two buttons above and below the scroll wheel to increase and decrease the CPI, and a default CPI button. Sadly, there's no RGB lighting zone.

This mouse isn't great for travel due to its fairly large size and wired-only design. However, this shouldn't be an issue for people looking for a gaming mouse for their desk setup.
It's somewhat heavy for its size, and unfortunately there's no way to optimize the weight.
The build quality is decent. The sides are made of slightly textured plastic which helps provide a better grip, but the top is a glossy, slippery plastic that feels a bit cheap. There's a small amount of flex when you squeeze the back, but it shouldn't be noticeable while using it. The buttons feel poorly made and aren't satisfying to click. There's a weird uneven pre-travel distance, where some buttons have longer distances than others. Also, the top buttons have a noticeable wobble.
This mouse feels comfortable to use, although people with small hands may not feel comfortable using it with any grip type. Due to its slight curve and left-side thumb rest, it's designed for right hands, and its sides have a textured detail on the plastic that helps with grip. However, the CPI buttons around the scroll wheel are awfully placed, and it isn't comfortable to reach them. The button in front of the scroll wheel feels much too forward, and the button behind the wheel feels too pushed back.
When used with a palm grip, people with small hands might struggle to reach the front side button as well as the button in front of the scroll wheel. People with extra-large hands might find struggle with the right and left clicks since their fingers may hang off the front.
When used with a claw grip, the front side button and the button in front of the scroll wheel may be difficult to reach for people with small hands.
People with small hands and medium hands may struggle to reach the front side button and the button in front of the scroll wheel when using it with a fingertip grip.
This mouse is wired and can't be used wirelessly.
This mouse has a decent cable. It's made out of rubber and retains kinks from the packaging.
The Logitech G MX518's feet are good. They glide well on both a mousepad and directly on a desk, although there's a slight scratchiness due to the sharpness of two straight edges. Although it doesn't come with replacement feet, third-party versions are available, but we haven't tested them.
The Logitech MX518 Hero has a wide CPI range that can be adjusted in increments of 50. The sensor remains fairly consistent whether you move the mouse fast or slow. You can choose between four polling rates: 125Hz, 250Hz, 500Hz, and 1000Hz.
The Logitech MX518 mouse has a great number of buttons. You can program every button through the Logitech G HUB software, including the middle click on the scroll wheel, but you can't program the up and down scroll. You can also assign a G-Shift button which allows for a second layer of programming.
The mouse wheel has a smooth rubber feel that isn't grippy at all. The steps aren't very pronounced and you can hardly notice it when scrolling up. Although you can feel the steps while scrolling down, the step definition feels slightly uneven. Also, there seems to be a slight lag when scrolling.
The clicks on the Logitech G MX518 are loud, but they shouldn't bother you unless you're in a very quiet environment.
The click latency is decent. Although it should be fine for casual gaming, it isn't recommended for competitive gaming. For a similarly-shaped mouse with much lower latency, check out the Nixeus REVEL Fit.
The Logitech G MX518 has excellent compatibility with the Logitech G HUB. It's very user-friendly, so you can remap the buttons and change the sensor settings very easily.
The Logitech MX518 gaming mouse has no variants. You can see the label of our unit here.
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.

The Logitech G502 HERO is better than the Logitech G MX518 Legendary. The G502 HERO feels better built and more comfortable. Also, it has a lower lift-off distance, many more programmable buttons, and a much lower click latency. 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, has a better cable, a much lower click latency, 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 Razer DeathAdder V2 is better than the Logitech G MX518 Legendary. The Razer feels better built, and its feet glide better. Also, it has a lower click latency, more programmable inputs, and a lower lift-off distance. However, the Logitech has a more consistent sensor, and it's fully compatible with macOS.
The Logitech G203 Prodigy is better than the Logitech G MX518. The Prodigy feels better built, is better suited for small hands, has a lower lift-off distance, and a better click latency. On the other hand, the MX518 has more programmable buttons, and its curved shape feels more comfortable.
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. However, the G5 has lower click latency and better quality PTFE feet.
The Logitech G MX518 Legendary and the Nixeus Revel Fit share the same unique right-handed shape. The Logitech has a wider CPI range, a set CPI that you can adjust more precisely, and a more consistent sensor. It also has more programmable buttons, including two on the front and back of the scroll wheel, and you can assign a G-Shift button for a second layer of programming. The Nixeus has much lower latency, and it has RGB lighting, which the Logitech lacks.
The Logitech G300s is better than the Logitech G MX518. The G300s feels better built, it has a lower click latency, and it's smaller, so people with smaller hands should be comfortable using it with a palm or claw grip. However, the MX518 has a much wider and more precisely adjustable CPI range, and its lift-off distance is lower.
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, it has a wider and more precisely adjustable CPI range, and its sensor is much more consistent. However, the Corsair feels better built, has a lower click latency, and has RGB lighting.
