Mad Catz R.A.T. 8+ Mouse Review

The Mad Catz R.A.T. 8+ has a very unique and futuristic look. The mouse looks modular and allows tons of customization options since you can change its shape and size. It also has RGB lighting that you can set inside its software.

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.

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.

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.

Thanks to the very large range of sizes and shapes you can give to the mouse, the Mad Catz R.A.T. 8+'s ergonomics are excellent. You're more than likely going to find a way to modify the mouse for it to fit your hand. However, there isn't a left-handed variant available.

Nobody should have any issues using the Mad Catz R.A.T. 8+ with a palm grip.

Nobody should have any issues using the Mad Catz R.A.T. 8+ with a claw grip.

Nobody should have any issues using the Mad Catz R.A.T. 8+ with a fingertip grip, although it might be easier if you completely remove the back panel where your palm would rest.

This is a wired-only mouse that can't be used wirelessly.

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.

• Mad Catz R.A.T. 8+ mouse
• 2 extra palm rest panels
• 1 side grip panel
• 1 side panel with pinky finger rest

You might off-center the sensor a bit if you drastically change mouse's shape and size configuration.

For a wired gaming mouse, the click latency is slightly higher, but this won't cause any issues for most players.

The Mad Catz RAT 8+'s performance is incredible. It has an insanely wide range of DPI settings, which you can adjust by increments of 50, meaning you're sure to find the perfect sensitivity for you. The mouse is also advertised to have an even higher maximum polling rate. However, when using a mouse rate checker application, instead of our usual test, we noticed that the overclocked polling rate was rather inconsistent, but could jump up significantly above 2000Hz too. Therefore, we don't recommend overclocking the polling rate and going over 1000Hz.

The Mad Catz R.A.T. 8+ has plenty of customizable buttons, but the left click and profile switching buttons aren't. On the upside, you can even reprogram every scrolling direction on both mouse wheels.

The Mad Catz R.A.T. 8+ has a vertical and a horizontal wheel, and both of them offer good feedback thanks to their incremented design. You can also remap the scrolling to whatever you want inside the software.

The Mad Catz R.A.T. 8+ Software offers plenty of customization options. You can set your RGB profiles on three different lighting zones and remap all the mouse's buttons to your preferences. 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.
