The Razer Viper is an excellent wired gaming mouse. It's very similar to the wireless Razer Viper Ultimate, although it has slightly inferior feet and doesn't come with a charging cradle. On the upside, the wired Viper is very lightweight and has amazing performance and low click latency. The mouse's shape is great for fingertip grip users thanks to its low-profile body and is very comfortable to use.

Our Verdict

7.6 Office/Multimedia

The Razer Viper is a good office mouse. It has a total of four side buttons that can be used to help you navigate your browser. It's very well-built and is comfortable to use for long hours. However, it isn't wireless and some people might find the cable to be bothersome.

Pros
  • Excellent performance; customizable.
  • Very well-built design.
  • Very lightweight.
Cons
  • Somewhat stiff cable; not as flexible as some other options.
8.6 Video Games (FPS)

The Razer Viper is an excellent FPS mouse. It has very low click latency and feels responsive. It's pretty light, which is great, especially since it doesn't feel flimsy at all. Also, its body has a low profile that is great for different grips, but especially for a fingertip grip. Its sensor performance is amazing, but the cable is a bit stiff and might drag on your desk.

Pros
  • Excellent performance; customizable.
  • Very well-built design.
  • Very lightweight.
Cons
  • Somewhat stiff cable; not as flexible as some other options.
8.1 Video Games (MMO)

The Razer Viper isn't designed as an MMO mouse, but with four side buttons, it has a few more inputs than most typical gaming mice. However, it doesn't have as many as dedicated MMO mice. Its performance is still excellent and its design is comfortable to use during long raids.

Pros
  • Excellent performance; customizable.
  • Very well-built design.
  • Very lightweight.
Cons
  • Somewhat stiff cable; not as flexible as some other options.
8.7 Ultra-Light Gaming

The Razer Viper is an excellent ultra-light gaming mouse. It's surprisingly lightweight for a non-honeycomb-patterned mouse and has amazing performance. However, it might be a good idea to use a bungee for its cable as it's not the most flexible and can create some drag.

Pros
  • Excellent performance; customizable.
  • Very well-built design.
  • Very lightweight.
Cons
  • Somewhat stiff cable; not as flexible as some other options.
4.9 Travel

The Razer Viper isn't designed for traveling. This wired mouse won't be ideal to use in tight spaces like a plane and isn't very portable.

Pros
  • Excellent performance; customizable.
  • Very well-built design.
  • Very lightweight.
Cons
  • Somewhat stiff cable; not as flexible as some other options.

This wired mouse is identical in style to the wireless Razer Viper Ultimate. It has an ambidextrous, low-profile design with an aggressive look. It has RGB lighting on the manufacturer's logo, but not around the scroll wheel. Overall, it looks like a high-end gaming mouse.

Like most wired gaming mice, it isn't the most portable. With its cable, it might be harder to put in a laptop case or use in tighter areas like on the plane. However, this shouldn't be an issue if you're looking for a gaming mouse to leave at home with your setup.

This mouse is very lightweight for a typical mouse. It's even slightly lighter than the Razer Viper Ultimate without its cable, but not quite as light as ultralight gaming mice like the Cooler Master MM710 or Finalmouse Ultralight 2 - Cape Town. If you like the Razer Viper and want something similar that's a bit lighter, however, check out the smaller Razer Viper Mini.

Build Quality

This mouse is very well-built. It feels the same as the wireless Razer Viper Ultimate, but with slightly inferior feet. On the upside, there's no rattling part and the mouse wheel feels durable. Also, the mouse click buttons are satisfying, although they wobble a bit. Just like the Ultimate, this mouse has optical switches for the main click buttons.

This wired mouse is extremely comfortable to use. It has a very low-profile and short design, which is great if you're a fingertip grip user. Both sides have nice, textured grips and the two side buttons on both sides are easy to reach. If you prefer a mouse that has a right-handed ergonomic shape, check out the Logitech G403 HERO.

Its cable is decent. It's better than the older Razer cables but not as good as the recent ones on their Ultimate lineup. Our unit's braided cable isn't very flexible, but on the upside, it's fairly lightweight. For a similarly performing mouse, but with a better cable, check out the Endgame Gear XM1.

This mouse has limited customizability with Razer Synapse 3. Although you can customize everything related to button-mapping, RGB lighting, and polling rate, the mouse doesn't have full on-board memory, so you won't be able to use this mouse on another computer with all your pre-saved settings. If you want a mouse with on-board memory and excellent software, check out the SteelSeries Sensei Ten.

Windows Compatibility Fully
macOS Compatibility Partially

While it's fully compatible with Windows, there are a few things that don't work on macOS. The right side buttons don't work in right-handed mode and since the software isn't available on this operating system, you won't be able to remap the controls to something other than their default settings. If you want a mouse that has software that can be installed on macOS as well, check out the SteelSeries Rival 310, though it doesn't perform quite as well overall.

Compared To Other Mice

The Razer Viper is an excellent gaming mouse that sets itself apart by its design. While it doesn't have a honeycomb pattern to reduce its weight, it's almost as lightweight as some that do. It's also very similar to the Razer Viper Ultimate but in a wired design. See our recommendations for the best gaming mice, the best wired mice, and if you'd prefer a wireless design, also check out the best wireless gaming mice.

Razer DeathAdder V2

The Razer Viper and the Razer DeathAdder V2 are very similar performing mice, and their main differences are shape and weight. The Viper has a lower profile body while the DeathAdder has a higher back hump. The Viper is also lighter than the V2 and has an ambidextrous design, while the V2 has a right-slanted design.

Razer Viper Mini

The Razer Viper Mini and the regular Razer Viper are both excellent wired gaming mice. The Mini is a bit lighter and smaller, making it better for fans of ultra-light mice or those with smaller hands. The cable of the Mini feels a bit better and maintains fewer kinks, but the sensor performance of the regular Viper is better, and it has a wider and more adjustable CPI range. The full-sized Viper also has two additional buttons on both sides, as opposed to just on the left side on the Mini. 

Razer Basilisk

The Razer Viper is a better mouse than the Razer Basilisk. It's noticeably lighter and has a lower click latency. Its cable is also slightly better. On the other hand, the Basilisk is better for palm grip users thanks to its ergo-shaped design with a thumb rest. It also has RGB on the mouse wheel and a sniper button. However, it only has a button on the left side, while the Viper has some on the right side as well.

Glorious Model O

The Razer Viper performs similarly to the Glorious Model O and is as lightweight, although it doesn't have a honeycomb pattern to reduce its weight. The Viper has two sets of side buttons and its body is slightly smaller than the Model O. However, the Model O is also available in a smaller size, which is called the Glorious Model O-. When it comes to the cable, the Model O's is noticeably lighter and more flexible.

Razer Mamba Elite

The Razer Viper is a better gaming mouse than the Razer Mamba Elite. It's lighter and its cable is slightly better as well. Its shape might be a bit better suited for fingertip grip users and people with smaller hands, but the Mamba Elite is better for people who like a palm grip and people with larger hands. If you're a fan of RGB lighting, the Mamba Elite also has side LED strips.

Razer DeathAdder Elite

The Razer Viper is a better mouse than the Razer DeathAdder Elite as it's noticeably lighter. However, some people may prefer the DeathAdder shape, especially if you're a claw grip user. The click latency is lower on the Viper, although most people won't notice the difference.

SteelSeries Sensei Ten

The SteelSeries Sensei Ten and the Razer Viper are both excellent gaming mice. However, the Viper is surprisingly lightweight for a non-honeycomb-patterned mouse and has amazing performance making it the better option for ultra-light gaming. The Viper is also more comfortable to use in an office setting.

Logitech G502 HERO

The Razer Viper is a better FPS gaming mouse than the Logitech G502 HERO. These two mice have very different shapes. The Razer has a low profile and is great for a fingertip grip while the Logitech is much bulkier and is more comfortable when using a palm grip. The Razer is noticeably lighter, but its scroll wheel doesn't have tilt inputs and can't be unlocked for infinite scrolling like you can do with the Logitech's wheel. Additionally, the Logitech's software is compatible with macOS, while the Razer Synapse software isn't.

Razer Viper Ultimate

The Razer Viper and Viper Ultimate are nearly identical. The Viper Ultimate is wireless, while the Viper is wired-only. The Viper is actually a few grams lighter than the Ultimate, but other than that, they are pretty much the same. You get a nice RGB charging cradle with the wireless Viper Ultimate and the cable is a bit more flexible. 

Endgame Gear XM1

The Endgame Gear XM1 and the Razer Viper are two very similar mice when it comes to performance. They're both very light and have a tremendous sensor performance. However, the XM1 has a noticeably more flexible and lighter cable than the Razer Viper. On the other hand, the Viper has RGB lighting on its back logo and has a lower profile with a slightly longer body.

Razer DeathAdder V2 Mini

The Razer DeathAdder V2 Mini and the Razer Viper are both excellent gaming mice. The Viper has a wider CPI range that can be adjusted more precisely than the DeathAdder V2 Mini, but its click latency is lower and it doesn't have onboard memory like the DeathAdder V2 Mini. The DeathAdder V2 Mini is also slightly lighter.
