The Mad Catz R.A.T. 8+ is a unique looking mouse that has a very futuristic design. Its body is modular, meaning you can move around pieces to change its shape and size for it to better fit inside your hand. This design makes it pretty much universal for small to extra large hands, regardless of your grip. Its wired click latency, although higher than some other mice, and many customizable buttons make it a good gaming mouse.

Our Verdict

7.5 Office/Multimedia

Very good for the office. Although it has a unique design that might too futuristic for an office, this mouse has excellent ergonomics thanks to its modular design that lets you customize the mouse's size and shape for it to fit your hand. It also has plenty of customizable buttons.

Pros
  • Customizable shape and size.
  • Universal for all hand sizes and grips.
  • Excellent build quality.
Cons
  • No left-handed variant.
  • Not travel-friendly.
  • Rigid cable.
7.1 Video Games (FPS)

Decent for FPS games. Its click latency is decent, but it's a very heavy mouse. On the upside, its performance is excellent and quite customizable to your preference. The mouse is also modular, meaning everyone should find a configuration that suits their hand for optimal control.

  • Customizable shape and size.
  • Universal for all hand sizes and grips.

5.6 Ultra-Light Gaming

This mouse is pretty heavy and isn't really an option for ultra-light gaming. There are ways to reduce the mouse's weight, but it still won't be comparable to ultra-light gaming mice.

  • Universal for all hand sizes and grips.
  • Excellent build quality.
Cons
  • No left-handed variant.
  • Not travel-friendly.

Cons
  • No left-handed variant.
  • Not travel-friendly.

This always-wired mouse is pretty big, which makes it harder to travel with. Also, we measured the Mad Catz R.A.T. 8+ at its smallest configuration, meaning that it can get significantly bigger than this, too. This won't matter for people who are looking for a desktop mouse to use at home.

The Mad Catz R.A.T. 8+ is pretty heavy, even when taking out the three optional weights that can be added. Even when stripping down the mouse from the palm rest and grips, it's still too heavy for lightweight gaming.

Build Quality

Although the mouse looks a bit weird and unique, it's built like a tank. The main frame is made out of metal with metal screws. The covering is made of plastic but still feels very well-built. However, due to the modular design, there could be potential longevity problems, but right out-of-the-box, it feels very sturdy. There are no squeaking or wobbling parts.

The cable is just okay. It keeps a few kinks from the way it's stored in the box, which is annoying. It's fairly rigid, but less inconvenient than Razer's cables.

This mouse also has onboard memory, meaning you'll be able to plug it into another computer and keep your settings. However, this customization won't be available on macOS.

Amazing mouse compatibility, as out of the box, all the buttons work on both Windows and macOS with their default bindings. However, you can't customize those on macOS, since the software isn't available on that platform.

Compared To Other Mice

The Mad Catz R.A.T. 8+ is a gaming mouse with a very unique design. It has many modular pieces, which make its shape and body customizable to suit your hand, regardless of its size and your grip. It also has a frame made out of metal, giving it a very high-end feel. However, its wired latency is a bit higher than most wired gaming mice, but most people won't notice it. Also see our recommendations for the best mouse for MMOs, the best wired mouse, and the best gaming mouse.

Logitech G502 HERO

The Mad Catz R.A.T. 8+ is slightly better than the Logitech G502 HERO. The Mad Catz is designed for any hand size with any grip type, it has less CPI variation, and it has a slightly wider CPI range. However, the Logitech has lower click latency, it has vertical wheel tilt, and it's fully compatible with macOS.

Glorious Model D

The Mad Catz R.A.T. 8+ is a bit better than the Glorious Model D. The Mad Catz is better-suited for people with small hands using the claw or fingertip grips, it has a better-performing sensor, and it has much more programmable buttons. However, the Glorious is lighter and it has lower click latency. 

Razer DeathAdder V2

The Mad Catz R.A.T. 8+ and the Razer DeathAdder V2 are two similar-performing mice. The Mad Catz has an extra programmable button, it's better-built, and it's suited for any grip with any hand size. However, the Razer has much lower click latency and it's much lighter.

Razer Viper Ultimate

The Razer Viper Ultimate is much better than the Mad Catz R.A.T. 8+. Despite being a wireless mouse, the Razer has much lower click latency. It also has an ambidextrous design and it's lighter. However, the Mad Catz has less CPI variation and it has an extra programmable button.
