Razer Cobra Lightweight Gaming Mouse

Top-class performance in a nice package

The Razer Cobra Pro is a wireless mouse that belongs to the top class. The sensor and switch performance are among the best on the market and the connectivity options make the mouse a suitable device for gaming, study and work.

Sensor:
The optical Focus Pro 30k sensor of the mouse is Razer proprietary and performs exceptionally well. The standard maximum polling rate is 1000hz and results in a 12.4 ms response time when starting a movement, 3.2 ms during a movement and 2.4 ms when stopping a movement. This places the mouse at the top of the rankings when it comes to sensor performance.

Click latency:
The click delay with this mouse is only 3ms, which can be reduced to 1.2 ms using the separately available 8k polling rate dongle from Razer. Don't be fooled by these statistics; 3ms is already extremely good. When shooting in games, the sound of the game runs together with the click of the mouse; a satisfying feeling!

Polling rate:
As mentioned earlier, the default maximum polling rate of the mouse is 1000hz. Using the software, this can be adjusted between 125hz to 1000hz or even 8000hz if you have the appropriate dongle. Please pay attention to this; If you want to make optimal use of the polling rate, the dpi (dots per inches) must be appropriate. If the dpi is too low, you will not make optimal use of the polling rate (unless you move the mouse very quickly). Moreover, a higher polling rate will demand more from your computer. 1000hz is more than enough for many people; 8000hz may make the mouse even more accurate, but it is difficult to notice the difference and will be at the expense of in-game performance. The polling rate via Bluetooth is usually a lot later (often 125 Hz), but I cannot determine this due to... the lack of Bluetooth on my PC. On my Android tablet the Bluetooth polling rate is 95Hz, but that may be due to the limitations of the Android device.

Connectivity:
The mouse can be used with a USB-A dongle, USB-A cable or Bluetooth. The USB-A and cable provide comparable performance. Bluetooth will be slightly slower and less accurate (8-10 ms), but this mode is also not intended for gaming. Having Bluetooth is a very nice extra for me, as many other mice in this class lack this function and I often use the mouse on my tablet or other devices without having to always move the USB dongle. It is also possible to connect the mouse to Android devices with the dongle or cable and this works properly. However, software support will be interrupted, but see the section on software.
Multiple Razer devices such as a keyboard can be connected to the dongle via the software. Replacement parts, such as the dongle, can also be ordered via Razer, which is reassuring if you are someone who often loses small objects. If the dongle is lost, the dongle and mouse can be paired via Razer software.
The dongle can be connected to a supplied extension to improve connectivity.

Weight, comfort and design:
The mouse is very light and quite small, namely 74.7 grams (the product specifications state 58 kilograms, which seems a bit much to me!). Compared to the competition, it is slightly heavier for the 'lightweight' theme, with the weight mainly located on the back of the mouse. This ensures that depending on how you hold the mouse, the mouse feels lighter or heavier and can influence how you move it. With my average hand size, the mouse is easy to hold in different ways (claw grip, palm grip or fingertip grip).
The build feels of high quality: there are no loose or rattling parts and the buttons each feel nice to press. The left and right mouse buttons give a nice, clearly audible 'click', and the other buttons sound fairly muffled. The sides are equipped with rubber/silicone strips that feel nice in terms of grip, but quickly become dirty or greasy.
The design of the mouse really appeals to me. It's small and looks modern, without giving off the extreme in-your-face gamer vibes. Depending on the RGB settings, you can make it look like a fairly modest mouse. The RGB lighting is located as a ring around the bottom of the mouse, in the scroll wheel and in the Razer logo and can be adjusted using the software. The ring gives off a glow on the surface, which creates a nice effect, but is less visible on a dark mouse pad during the day.

Battery:
The battery can easily last a week, depending on your RGB and polling rate settings. I use it with the RGB brightness at 37% and a polling rate of 1000hz. I cannot yet determine the battery life when using Bluetooth.

Software:
The Razer software is clear and offers many options. The RGB options are versatile and can be linked to other devices. The polling rate, button mapping and lift-off distance can also be easily adjusted.
While the sensor settings are saved locally, as are DPI profiles, RGB settings do not seem to be. Only when the mouse connects to the software will the mouse adopt the chosen color profile. The Razer software is also considered a resource-intensive program.
