Razer Cobra Pro  Mouse Review

This mouse has a matte black plastic body with glossy plastic accents and textured rubber side grips on either side. There's a Razer brand emblem on the palm rest and a total of 11 independently customizable RGB zones: One in the scroll wheel housing, one embedded behind the Razer logo on the palm rest, and nine zones positioned around the bottom rim of the mouse that provide an underglow effect.

If you want a wireless mouse with the same shape in this product lineup and prefer plastic sides instead of rubber sides, check out the Razer Cobra HyperSpeed.

This mouse shares virtually the same dimensions as the original Razer Viper Mini. The Razer Cobra Pro is marginally longer and slightly wider since this mouse has rubber grips on either side that the Viper Mini lacks.

This mouse has impressive build quality overall. Its body is made of solid plastic that feels sturdy and has a smooth but not slippery material finish. There's minimal side-to-side travel in the left- and right-click buttons, and no loose or wobbling parts of rattling sounds if you shake the mouse. While there isn't any noticeable flexing in the body, the mouse makes some creaking noises when you apply deliberate pressure to the underside, particularly into the mouse's sides. The creaking is minor but sometimes noticeable when gripping the mouse normally.

This mouse is relatively lightweight, making it easy to move quickly and accurately. The weight is concentrated slightly more towards the back of the mouse. If you're interested in a much lighter wireless gaming mouse with a similar shape, check out the Keychron M3 Mini, the LAMZU Atlantis Mini 4K, or the Hitscan Hyperlight.

The lowest weight result is achieved by removing the plastic puck on the bottom of the mouse that covers the battery compartment. This plastic puck weighs 2g.

This mouse has a low-profile, symmetrical shape with two side buttons on the left. The dimensions of this mouse are virtually identical to those of the Razer Viper Mini. Much like the Viper Mini, this mouse is best suited for small or medium-sized hands and ideal for a fingertip grip.

The shape and size of this mouse also make it suitable for a claw or, to a lesser degree, a palm grip for smaller hands. If you're looking for a mouse that's more suitable for larger hands, check out the Razer Viper V3 HyperSpeed.

Razer advertises that this mouse has a battery life of up to 100 hours when connected wirelessly with its USB receiver, using the stock maximum polling rate of 1000Hz or up to 170 hours when connected via Bluetooth.

Razer also offers several accessories for this mouse available as a separate purchase that provide additional wireless capabilities, detailed below.

• The Razer HyperPolling Wireless Dongle allows you to increase the mouse's maximum polling rate setting to 8000Hz. For more information, see Razer's product page here.
• The Razer Wireless Charging Puck replaces the plastic puck on the bottom of this mouse and allows you to charge the mouse with Qi-certified wireless chargers. For more information, see Razer's product page here.
• The Razer Mouse Dock Pro is a wireless charging dock with a Wireless Charging Puck and an integrated 8kHz transceiver, increasing the mouse's maximum polling setting to 8000Hz. For more information, see Razer's product page here.

If you're looking for a wireless gaming mouse that uses replaceable AAA batteries instead of an integrated rechargeable one, check out the SteelSeries Rival 3 Wireless Gen 2.

This mouse comes with what Razer calls a 'Speedflex' charging cable. It feels durable and is fairly lightweight and flexible.

However, this cable is noticeably stiffer and retains slightly more kinks from its packaging compared to the 'Speedflex' charging cables included with other recent Razer releases, including the Razer Viper V2 Pro, the Razer DeathAdder V3 Pro, and the Razer Basilisk V3 Pro.

This mouse has remarkably good feet that glide very smoothly on mousepads and directly on desks with minimal drag and only minor friction noises.

You can reprogram all of the buttons on this mouse, including the left- and right-click buttons and the profile button on the underside. However, one button must always be set as the primary click button. You can also assign a 'Hypershift' button to toggle to a secondary layer of programmable inputs.

The left- and right-click buttons use Razer's Gen-3 optical switches. Razer advertises that these switches have an estimated lifespan of 90 million clicks.

This mouse has exceptionally low and very consistent click latency. It delivers an extremely responsive-feeling experience for gaming in any genre and is well-suited for casual or competitive play. We tested this mouse at its native maximum polling rate setting of 1000Hz.

We also tested this mouse at a polling rate of 8000Hz using Razer's HyperPolling Dongle, which Razer sells separately. Using the HyperPolling Dongle, we measured the click latency at 1.2 ms. You can see an image comparing our results here as well as a video of our testing at 8000Hz here.

This mouse offers exceptional CPI performance. Its sensor delivers outstanding tracking accuracy, and the physical movements you make with your mouse translate extremely close to your cursor movements on-screen.

This mouse provides superb sensor latency performance. The sensor reacts exceptionally quickly when you move your mouse, and these movements match the timing of the cursor movements you see on the screen extremely closely. This mouse was tested at the maximum stock polling rate setting of 1000Hz.

We also tested this mouse at a polling rate of 8000Hz using Razer's HyperPolling Dongle, which Razer sells separately. Using the HyperPolling Dongle, we measured slightly worse delay to start of movement results at 13.1 ms but a better delay of half movement result of 1.8 and a better delay to end of movement result of 2.2 ms. You can expect slightly better and more consistent overall tracking performance using an 8000Hz polling rate. You can see an image comparing our results here as well as a video of our 8000Hz testing here.

The stock available polling settings are 125Hz, 500Hz, and 1000Hz. This test was performed using a polling rate of 1000Hz.

The Razer Cobra Pro is compatible with Razer's Hyperpolling Wireless Dongle, available separately on Razer's website. This additional receiver allows you to increase the wireless polling rate to a maximum of 8000Hz. For more information, see the product page for the Hyperpolling dongle here.

This mouse has a rubberized scroll wheel with small bumps for added grip. The scroll click button has a satisfying tactility and doesn't take too much force to activate. Scrolling feels precise, and each step feels very well-defined. There's also a relatively quiet but noticeable noise made between steps.

The noise made by the left- and right mouse clicks, all buttons, and the scroll wheel are all fairly quiet.

This mouse uses Razer's Synapse 3 software, which is well laid out and generally easy to navigate. This software allows you to customize various expected options, including RGB lighting, CPI, button programming, polling rate, lift-off distance, wireless power settings, and custom profiles.

However, much like similar software options from other major manufacturers, this software is the source of criticism from the broader community. While we didn't experience any issues during the testing of this mouse, many users online criticize this software for requiring frequent updates and taking up disproportionate system resources, among other complaints. This software may be frustrating if you prefer more lightweight software options or no software at all.

Only the new version of this software, Razer Synapse 4, is available for macOS.

All default button functions work in Windows and macOS. The macOS software is only available on Macs with Apple silicon.
