SteelSeries Rival Pro Review

Design

• More contoured shape
• Lightweight and sturdy with dense plastics
• Minimal button arrangement

The Rival line of SteelSeries mice has been the more ergonomic shape against the more neutral Sensei, and that doesn’t change here. It takes the familiar feel of a Rival, and optimises it for more modern tastes with a mean and minimalist look in either black or white, complete with a splash of colour with an orange scroll wheel.

SteelSeries has said it has redesigned both the new Rival Pro and its sister, the Sensei Pro, in conjunction with pro players and key influencers to get the right feel.

At just 53g, it’s especially light, although the plastics used in its construction feel dense, so the Rival Pro doesn’t feel like a cheap mouse. It’s also competitive against the 50g the Viper V4 Pro is, and is some eight grams lighter than the G Pro X2 Superstrike. The weight saving has even gone so far that you won’t find a USB-C port at the front, but there’s a good reason for that.

The ergonomic shape, with a more contoured finish, makes this feel more like the Logitech G Pro X Superlight 2 Dex, which I think makes it better suited for productivity tasks as much as for gaming. After all, I’ve always been a fan of more shaped mice, rather than the increasingly homogenous shape that ultralight wireless mice have tended to have in recent years. 

The button arrangement here makes sense, with the two main ones and a scroll wheel on top, plus two side buttons on the left, and one for DPI switching and power on the underside. You’ll also find this rodent’s innovative swappable battery system on the underside, but I’ll get into that a little later on.

SteelSeries has been through a lot of trouble to save weight with this mouse to accommodate all of its clever internal trickery with UWB and the swappable battery system, such as using mechanical means to attach the battery, rather than magnets and going through multiple revisions of the internals to get the weight distribution right while keeping the mass down as low as it can be without compromising on the Sensei Pro’s internal structure.

Performance

• Fast 42,000 DPI sensor
• True 8000Hz polling
• Clever UWB connectivity and swappable batteries

SteelSeries hasn’t held anything back on the internals of the Rival Pro, throwing genuinely flagship-tier hardware at a mouse that already has to compete in one of the most crowded categories going.

Front and centre is a new TrueMove 42K Pro sensor, capable of up to 42,000 DPI. In practice, it’s precise and quick to respond – testing it extensively in Counter-Strike 2, it’s up there with the best sensors I’ve used, full stop.

Underneath, it’s a custom PixArt 3955 sensor running at the 20,000 FPS capture on offer. SteelSeries went to PixArt and asked for it to be tuned to its maximum rate purely for accuracy’s sake, which is exactly what the mouse’s Max Performance mode is built to take advantage of.

That said, 42,000 DPI is overkill for most day-to-day scenarios and can feel twitchy at that ceiling – though it does come into its own for fast wrist flicks and quick rotational aim. For actual CS2 sessions, I settled around 1600 DPI, and closer to 3200 DPI for general desktop use, and the Rival Pro stayed sharp and responsive at both.

Polling is rated at a genuine 8000Hz, achieved by oversampling a 9000Hz internal readout even where the connected PC can only process 8000Hz. That same approach covers both cursor tracking and click input from the onboard optical switches (configurable in software), so you can dial in settings as you wish.

The headline addition, though, is an Ultra Wide Band wireless connection, which needs a bigger, more complex antenna setup than standard 2.4GHz. The reasoning is straightforward: the more traditional 2.4GHz band is getting crowded, with most homes now packed with devices competing for the same spectrum. UWB sidesteps that by operating in the 6–9GHz range and spreading data across multiple channels, giving roughly 20 times the bandwidth of 2.4GHz and a more stable connection as a result.

Put together, the Rival Pro is a phenomenal gaming mouse. Much of what’s under the hood is honestly beyond what most of us mere mortals could ever perceive in practice, but the ergonomic shell makes it easy to appreciate regardless – it sits comfortably for long sessions while still feeling light, quick, and endlessly responsive when the moment calls for it.

Naturally, this level of performance tends to come at the cost of battery life. SteelSeries has worked around that with a swappable battery design: expect up to 16 hours per battery at full performance, or 32 hours total across the two included. Dial polling back to 1000Hz, and that stretches to 60 hours per battery, for 120 hours combined.

Software and Lighting

• Extensive software customisation with GG suite
• No RGB lighting to speak of

SteelSeries has employed its tried-and-tested GG suite for the Rival Pro, offering a range of customisation on everything from DPI to polling rate and button remapping to lots more besides. 

You can choose DPI on separate X and Y axes, alongside the polling rate for both clicks and sensor and enable the Max Performance mode mentioned above. Alongside this, GG provides you with the option to match your sensitivity to a previous mouse you’ve used for a seamless transition to your new one. There is a new version of the brand’s 3D Aim Trainer coming in the future called Performance Coach, which can keep you warmed up in between downtime in certain games and tell you where you’re going wrong, which is very clever.

There is also the option of GG Web, which provides a web-based UI that runs in a browser and pares back some features, but is another choice if you can’t install software on a PC but still want some customisation – handy for eSports tournaments that are traditionally played on locked-down PCs. It’s the first time SteelSeries has offered this, which is nice. To get the full functionality, though, you’ll want to use the proper GG suite.

As is common for ultralight gaming mice, you won’t find any flashy RGB lighting with this Rival Pro either, in the name of conserving battery and looking mean
