SteelSeries Prime Mini Wireless
MSRP $130.00
“The $130 SteelSeries Prime Mini Wireless feels a step below other esports mice.”
  • Sturdy and ergonomic design
  • Crispy optical magnetic switches
  • Long battery life
  • Super light
  • Large USB-C dongle with no storage
  • Expensive
  • Too small for most hand sizes

You don’t normally think of high-end esports mice in a portable form, but that’s what the SteelSeries Prime Mini is. It takes the light ergonomic design of the Prime Wireless and cuts it up to create a gaming mouse that’s not only smaller, but lighter, too.

SteelSeries didn’t cut features out to achieve a slim form. The Mini still packs the same sensor, optical magnetic switches, and buttons as its full-size counterpart. With both mice at the same price, though, the Prime Mini feels like a downgrade for most hand sizes.

That’s not to mention how it stacks up to the best gaming mice. Although a high-end esports mouse with a spec sheet to match, the Prime Mini doesn’t reach the same heights as its competitors. Its design and switches are second to none, though, which may be worth it if you pick up the full-size model.

There aren’t a lot of mini gaming mice around, and the SteelSeries Prime Mini doesn’t change that despite its name. It’s only slightly smaller than the full-size Prime, shaving 1.7mm on the height, 1.7mm on the width, and most importantly, 5mm on the length. It also cuts down the weight from 80 grams to 73 grams. That’s light, but not as light as the Logitech G Pro X Superlight at 63 grams.

Although smaller than the SteelSeries Prime, the Mini isn’t smaller than a lot of wireless esports mice all around. The Logitech G Pro Wireless is shorter and thinner, and the Razer Viper Ultimate is shorter and thinner than both of those.

The difference is the length, where the Prime Mini shaves about 5mm off mice of similar caliber. The change to the height never bothered me, but the length and width did. Even with smaller hands, it never felt like I had enough to hold onto in palm grip, with the back end of my palm slipping off the mouse onto my desk. Similarly, the smaller width meant that I was dragging my pinky along.

I really missed the extra length and width on the Prime Mini.

Claw grip was a lot more comfortable, which is the case with most smaller gaming mice.

Still, I can appreciate the design. The Prime Mini feels like the Corsair Sabre Pro Wireless with a more aggressive slant. The right side of the mouse juts out on the back, and there’s a fairly deep indent on the left for your thumb.

I love the design and how the mouse feels — it comes with sturdy plastic that doesn’t feel hollow like the Razer Viper Ultimate, and it rested almost too well in my palm. I just wish I could have experienced the design in its proper form. I really missed the extra length and width on the Prime Mini, which ruined what would otherwise be probably one of my favorite gaming mice.

Sensor and buttons

SteelSeries says the Prime Mini comes with “crispy clicks,” and they are the crispest clicks I’ve ever experienced. There’s a loud, satisfying snap with each press, which is due to the Prestige OM optical magnetic switches under the hood. The Razer Basilisk V3 has optical switches, too, but they don’t feel as crisp as the Prime Mini.

Because the switches are optical, they aren’t subject to debounce delay like mechanical switches.

This is my favorite aspect of the Prime Mini. The switches are as satisfying as can be, and because they’re optical, they aren’t subject to debounce delay like mechanical switches. SteelSeries rates the lifespan for 100 million clicks, too, doubling the 50 million click lifespan on most high-end gaming switches.

In addition to left- and right-click, the Prime Mini comes with forward and back thumb buttons, as well as a DPI button to toggle through the five customizable presets. The DPI button is on the bottom side of the mouse, which is annoying, but it makes sense. This is an esports mouse, and you don’t want to bump your DPI around in the heat of battle.

The switches are the star of the show while the sensor takes a back seat. The mouse comes with SteelSeries’ TrueMove Air 18K DPI sensor, which you can adjust in 100 DPI steps. At $130, that’s behind the curve. The Logitech G Pro X Superlight has a 25K DPI sensor, and the Corsair M65 RGB Ultra Wireless has a 26K DPI sensor. The Corsair mouse has a 2,000Hz polling rate, too, while the Prime Mini is locked to 1,000Hz.

It’s accurate and fast, but not as much as the competition.

Connectivity and battery life

The Prime Mini comes with Quantum 2.0 Wireless technology, which offers “performance that feels just like wired,” according to SteelSeries. Although I’m far from an esports player, the wireless connection never posed a problem in Destiny 2 raids or my recent addiction to New World

SteelSeries claims 100 hours of battery life, likely due to only a strip of RGB lighting around the scroll wheel. After using the mouse for almost a week, I only knocked off about a third, so you’ll have a lot of time between top-ups. Plus, the mouse supports fast charging through the USB-C port.

Quantum is your only option, though. Despite a trend toward Bluetooth and low-latency wireless on mice like the Logitech G604, the Prime Mini only comes with SteelSeries’ wireless connection. That’s not a huge deal, but I always like having Bluetooth as an option for using the mouse with my home theater setup.

The wireless is solid, but I can’t wrap my head around the wireless dongle. It uses USB-C instead of USB-A. Most motherboards only come with a single USB-C port, and only the most recent cases come with a USB-C port upfront. I have a lot better things to occupy my USB-C ports with than a wireless mouse dongle.

Worse, it’s a big dongle. It’s about an inch long ignoring the connector, which compares to about a quarter on an inch on Corsair and Razer dongles and a third of an inch on Logitech models. The Prime Mini is primed for travel given its small and light design, but there’s nowhere to store the dongle on the mouse like there is with basically all other high-end wireless gaming mice.

SteelSeries includes an adaptor so you can hook it up to your machine with USB-A. This just doesn’t feel like the best solution. I would’ve much preferred a USB-A dongle I could store underneath the mouse instead of a chunky USB-C one that’s just waiting to get broken while plugged into my laptop.

Gaming performance

I have some niggles with the Prime Mini, but there’s no denying it’s a solid gaming mouse. There’s tactile feedback with any mouse, but I felt it on the Prime Mini. Each shot in Destiny 2 or in my endless runs of Deathloop felt like they mattered, with the Prestige OM switches bringing a sense of depth to every click.

That’s not the reason to buy this mouse, but it’s a nice bonus given the mouse’s overall gaming performance. The sensor may fall behind the competition, but it’s still fast enough to hold up in twitchy shooters like Valorant and sweep around the screen to activate a skill in Final Fantasy XIV. 

The Prime Mini is tiny, sturdy, and light.

Size proved to be an issue once again, though. I found myself wanting to switch back to my tried and true Razer Viper Ultimate while playing just so I had a little more to hang onto. The Prime Wireless and Prime Mini Wireless are the same price from SteelSeries, and I’d recommend sticking with the full-size model for most hand sizes.

For gaming, I could see myself using the Prime Mini Wireless while traveling. It’s tiny, sturdy, and light, making it an excellent high-end travel companion for gaming. As mentioned, though, the large dongle and lack of storage for it puts a damper on the travel experience.

Our take

The SteelSeries Prime Mini Wireless is a gaming mouse of high quality and unfortunate design decisions. The shape is remarkably comfortable, but it’s too small, and the optical magnetic switches are excellent, but they’re paired with a sensor that falls short of the competition. It’s not a bad mouse, but it’s not the best — and at $130, being the best is important.

Are there any alternatives?

The SteelSeries Prime Mini trims about 5mm off of the length of most competing mice, so there aren’t many direct alternatives.

If you don’t mind a little extra length, it squares off against the Corsair Sabre Pro Wireless, Logitech G Pro X Superlight, and Razer Viper Ultimate.

How long will it last?

The Prestige optical magnetic switches are rated for 100 million clicks. Assuming 10,000 clicks a day, that comes out to just over 27 years before the mouse wears out. Basically, it will last until you decide it’s time to upgrade.

Should you buy it?

No. The full-size Prime Wireless will be more comfortable for most people, and it’s a decent option at $130. The one exception is for those with small hands. There aren’t a lot of small, high-end gaming mice. The closest competitor is the Logitech G305 which is cheaper, but also heavier and with lower specs. Otherwise, pick up the full-size version.

SteelSeries’ wireless gaming mouse is charged for battle in 15 minutes
SteelSeries Rival 650 Wireless Gaming Mouse

Wireless mice typically aren’t the first choice for most gamers; input lag can be a hindrance on performance and power-hungry batteries can leave players dead in the middle of an intense battle. SteelSeries thinks it can change all that with its new Rival 650 gaming mouse -- the first wireless mouse with fast charging and only 1ms of latency. Modeled after the wired Rival 600, SteelSeries hopes to bring the benefits of wireless to the gaming world.

Powered by an internal battery, the Rival 650 can deliver over 10 hours of charging time with only 15 minutes of charging. While the mouse packs a healthy 24 hours of battery life, gamers should be able to feel a bit more confident that they won’t find themselves left in the dust with its fast-charging abilities. Of course, players can still choose to go wired with the included detachable soft rubber cable if they desire.

SteelSeries serves up the first Hi-Res Audio-certified headset for gamers

Despite the boom in technology regarding graphics cards and gaming displays, SteelSeries believes speakers and headphones are severely behind the times. That is where the company's new Arctis Pro + GameDAC headset comes into play; it supposedly takes gaming audio to an entirely new level thanks to "breakthrough" technology cranking out hi-fidelity sound for a more immersive experience. 
SteelSeries says the new flagship headset is the first in the gaming industry slapped with the Hi-Res Audio label. Hi-Res Audio is a certification platform introduced by the Digital Entertainment Group, The Recording Academy, record labels, and other audio-focused organizations in 2017 to promote devices that deliver sound at CD-level or higher quality.  
“Until now, innovation in gaming graphics and displays have outpaced progress in gaming audio solutions,” SteelSeries CEO Ehtisham Rabbani said in a statement. “The Arctis Pro is designed for gamers who seek high-fidelity audio and who want to hear everything the sound engineers created, the same way they seek high-res, immersive visuals.” 

The new headset relies on the ESS Sabre 9018 Reference DAC chip to produce 96kHz/24-bit audio without the need to downsample. The headset also includes two 40mm drivers with a frequency response of up to 40,000Hz, almost double what you find with standard gaming headsets. Other highlights include 121 decibels of dynamic range and 95 decibels of total harmonic distortion and noise. 
Packed with this Arctis-branded headset is a USB-based digital-to-analog converter and amplifier for gaming. This unit consists of an embedded OLED screen so you can visually balance the game and chat audio, keep track of the volume levels, and tweak the 10-band equalizer bars. The device also includes a dedicated Hi-Res Audio mode for the best audio quality, and onboard controls for PlayStation 4 streaming. 
While the Arctis Pro and GameDAC costs a hefty $250, the vanilla Arctis Pro unit is easier to swallow at a cheaper $180. It's not a Hi-Res Audio-certified system, as the GameDAC unit isn't included with this model. But like its more expensive sibling, this model includes the company's Prism RGB illumination system supporting 16.8 million colors. It also supports ClearCast microphone technology for "studio-quality" chats, Headphone:X v2.0, and includes an in-line dial to balance game and chat audio.

Steelseries’ TrueMove3+ optical sensor debuts on Rival 600 gaming mouse
steelseries rival 600 truemove3 rival600 02

Steelseries has unveiled a brand new gaming mouse at CES 2018: The Steelseries Rival 600. But as impressive as the overall package is, it's the sensor system it employs that has tongues wagging. The TrueMove3+ dual sensor setup tracks general player movements and lift-off distance more accurately than ever before.

One of the biggest considerations to make when purchasing a new gaming mouse is what sensor type to go for. Optical ones tend to lack any form of acceleration, while laser sensors operate better on different surfaces. Now gamers need to consider whether they want to go for a gaming mouse with just one sensor, or opt for Steelseries' new dual-sensor design.
