Watch out, there’s a new snake in town: With the Cobra product line, which was only introduced at the end of June, peripheral manufacturer Razer expands its portfolio of gaming mice with two new models. With a symmetrical design and compact dimensions, the rodents also want to serve smaller hands, while the latest technology slumbers under the hood. Our Razer Cobra Pro review clarifies whether the venomous snakes bite their way to the top of the best gaming mice.

Razer Cobra Pro: design and build
- Symmetrical design
- Grippy, rubberized sides
- High-quality workmanship
Measuring around 120 mm x 62.5 mm x 38.1 mm and weighing 77 grams, the Razer Cobra Pro marks something of a slightly smaller (but heavier) version of the Viper V2 Pro, which we called the manufacturer’s best gaming mouse to date in our review last year.
The Cobra also relies on a symmetrical design that is supposed to appeal to left- and right-handers alike. In fact, the nager is visually reminiscent of the V2 Pro in many respects, but it has a few differences.
The most important thing for real gaming fans: While the Viper remained unlit, the Razer Cobra Pro features the iconic Chrome RGB lighting. The lighting can be individually adjusted in eleven lighting zones, including a colorful underbody lighting (if desired).
The ribbed and rubberized side parts of the rodent are also eye-catching and very pleasant. They contrast nicely with the matte look and also significantly improve the feel of the mouse.
The clickable scroll wheel also features the rubber coating and scores with a pleasantly precise grid. In addition, the bright frame around the mouse wheel can now be illuminated as well. On the underside, we find two wide PTFE gliding feet in white, as well as an additional area around the sensor, which offer excellent gliding properties.
The USB-A receiver can be stored in the magnetically holding, screwable lid underneath. In addition, the manufacturer’s Charging Puck can be used here to wirelessly charge the Cobra Pro on the Razer Mouse Dock.
In addition, two dedicated buttons on the bottom can be used to switch between up to five onboard profiles, while the mouse powers up here and allows switching between Bluetooth and 2.4 GHz wireless operation.
The USB-C port for charging is located on the front, though the mouse can still be used with the cable connected. A high-quality, fabric-covered USB-A to USB-C cable is included with the rodent.
The build quality of the Razer Cobra Pro is excellent. Everything feels very sturdy and of high quality. There is absolutely nothing to complain about here.
Practical and sensor test of the Cobra Pro
- Eight programmable buttons
- Long-life optical switches
- For small to medium hands
The Razer Cobra Pro comes up with a total of eight programmable buttons, with the number of customizable controls increasing to 10 if you assign both directions of the scroll wheel individually.
The manufacturer relies on high-quality optical mouse switches from their own production for the two primary keys, which are supposed to have a life span of up to 90 million clicks and trigger pleasantly fast. Yes, we already know them, among others from the Viper V2 Pro. The click noise is not necessarily the most powerful, but very pleasant.
With its compact body, the gaming mouse is best suited for claw or fingertip grip. Only users with particularly small hands should also be able to reach for the Palm grip.
Combined with the weight of around 77 grams, the new mouse treads a middle ground, so to speak, between the ultra-light models and the larger, heavier mice with more buttons, which makes it a bit more difficult to classify it in the target group.
Esports-oriented gamers might find the Nager a bit too heavy, and it lacks additional keys for MOBAs and MMOs. But quite honestly:
I find the Razer Cobra Pro very comfortable to use, which is also due to my rather small hands. It feels very comfortable in the hand and is neither too heavy nor too light. The number of additional keys offered is completely sufficient for me.
On the other hand, there are rodents on the market that do exactly that (with the exception of the beautiful RGB lighting) at a much lower price. At least at first glance, because with the installed technology, it gets interesting with the Cobra.
Sensor test and performance of the Razer Cobra Pro
- Excellent 30,000 DPI sensor
- Precise tracking
- DPI differences between Bluetooth and wireless
Razer equips the Cobra Pro with its own Focus Pro sensor, which realizes a resolution of up to 30,000 DPI. We already know this from the Viper V2 Pro as well, where it also achieved excellent results and wowed with outstanding precision on different surfaces.
The 750 IPS tracking speed and 70G mouse acceleration also secure the new gaming mouse a place high up in the performance leaderboard. Thanks to newly added Bluetooth connectivity, the nager can also be used in a power-saving way with PC and notebook, tablets or smartphones if you don’t care about maximum performance.
This is because the latency is minimally higher than in wireless mode, where it is again barely noticeable. Thus, HyperSpeed wireless mode is once again recommended for competitive gamers, but everyone else will also be satisfied in Bluetooth mode.
Thanks to the grippy sides, the Cobra Pro provides a pleasant feel even in long-term use in conjunction with the very high performance. The polling rate of 1,000 Hz is absolutely sufficient in my eyes. However, those who like can increase this to 4,000 Hz with the optional Hyperpolling Wireless Dongle.
What I did notice, however, is that the DPI settings differ between Bluetooth and wireless modes. Normally, I use 3,200 DPI, which via 2.4 GHz receiver is also the speed I’m used to. Via Bluetooth, however, the same 3,200 DPI turns out noticeably faster and should correspond to around 4,000 DPI. A bug? Probably.
Excellent battery life of the Cobra Pro, but…
- Excellent battery life…
- … However, only with deactivated illumination
The manufacturer advertises the Razer Cobra Pro with a battery life of up to 100 hours in HyperSpeed wireless mode, as well as up to 170 hours via Bluetooth, which are excellent values.
However, this is only half the truth. Based on my measurements, the gaming mouse should actually reach these values, but only if the RGB lighting is omitted.
It should be clear that these eleven light zones suck quite a bit on the battery. In fact, the battery life is reduced to around 40 hours when the illumination is deactivated at full brightness. That is of course still a good value, but far from what one would have expected based on the manufacturer’s specifications.
It’s a shame, because the gaming mouse’s RGB lighting is really top-notch and, being largely confined to the underside, quite subtle and pleasant to use.
App connectivity: Razer Synapse
The companion app for the Cobra Pro, as always, is Razer Synapse. After the initial connection with the mouse, the drivers and menus are downloaded automatically, and it is also possible to operate without any software at all.
Synapse scores with a tidy design, but the settings options depend on whether the mouse is operated via wireless or Bluetooth. The tabs or options for setting the sampling rate and the surface calibration, for example, are only available in wireless mode.
The range of functions is as expected. Besides the possibility to freely assign all buttons and save them in a total of five onboard profiles directly on the nager, you can customize the RGB lighting down to the last detail and synchronize it with other Razer devices.
The smart dimming feature that turns down the lighting in wireless mode to 0 percent, 25 percent or 50 percent when the mouse is not in use proves to be especially handy.
Razer Cobra Pro review: conclusion
The Razer Cobra Pro is something like the manufacturer’s ideal mouse for everyone. Lightweight, but not ultra-lightweight. Symmetrical and thus, although the additional keys can only be found on the left, also suitable for left-handers. Small, but not too small – so that players with small and medium-sized hands are served excellently.
The build quality is impeccable, and the rubberized sides are a pleasant addition. Eight programmable buttons are perfectly sufficient for most applications in my eyes. And the RGB lighting is a successful addition for those who like it – especially since Razer implemented it excellently.
Those who need more buttons or a larger mouse will find suitable alternatives. Be it from Razer or other manufacturers. However, two points of criticism remain: On the one hand, the battery life decreases rapidly when the RGB lighting is enabled, and on the other hand, the price is quite high.
However, Razer cannot necessarily be blamed for the latter, since competitors with a similar performance level are just as expensive or even cost more. So, if you are looking for a convincing all-rounder in the field of gaming mice that also does an impeccable job in everyday office use, you will definitely find what you are looking for in the Razer Cobra Pro.

94/100
High-performance, precise and high-quality wireless gaming mouse that scores with strong RGB lighting and good battery life. However, the runtime drops significantly when the illumination is active, and the price is also quite high.
