One-minute review
The SteelSeries Nimbus Cloud positions itself as the “world’s first true dual-mode cloud controller”. It starts out as a generic-looking Bluetooth gamepad before doing its best Autobot impersonation and extending out to become a mobile grip that connects to your phone via USB-C, too.
It’s a clever idea and it’s backed up by an impressive spec sheet that ticks all the usual premium controller boxes. Hall Effect thumbsticks and triggers, mechanical face buttons, programmable rear buttons, and compatibility with Mac, PC, iOS, and Android.
That all sounds great, but after a week of using the Nimbus Cloud, it sadly lived up to its name. Cumulonimbus clouds are the type that bring heavy rain and thunderstorms, and my parade has been well and truly rained on.
When it works, it’s not a bad controller and falls neatly in line with the likes of the stock Xbox Wireless Controller. However, for a $149.99 / £129.99 / AU$359.99 controller, the Nimbus Cloud simply has too many flaws that spoil the day-to-day experience. There’s a list of buts coming here and it doesn’t make for particularly pleasant reading.
Build quality is fine, but it’s generic rather than carrying any kind of premium vibe. The triggers use Hall Effect sensors, which is good, but they feel mushy and throttle control in racing games proved a frustrating experience. The mechanical face buttons are crisp, but over both Bluetooth and USB-C I encountered missed inputs when pressing them more than once.
My iPhone 17 Pro fit, but it was far from a secure hold and it required the removal of the rubber inserts, leaving the phone resting and rubbing against bare plastic. SteelSeries lists Mac as a compatible platform, but my testing on a MacBook Air was a mess, with inverted sticks, wrongly mapped inputs, and Steam not playing nice either.
If this were a cheaper option or first attempt from a challenger brand then I’d find it easier to focus on the decent core elements and look past the finer details. However, at $149.99, you’re paying over the odds for an under par experience, regardless of which mode you’re running it in.
SteelSeries Nimbus Cloud: Price and availability
- Costs $149.99 / £129.00 / AU$359.99
- Available from SteelSeries and some third-party retailers
- Released September 2025
The SteelSeries Nimbus Cloud is a relatively new addition to the range, launching in the back half of 2025 at $149.99 / £129.99 / AU$359.99. That’s top-end territory for a mobile grip or PC controller on its own, though it’s certainly more palatable for a device aiming to be both in one.
For comparison, the Backbone Pro mobile grip and Razer Wolverine V3 Pro PC controller will both set you back around the same on their own. But you could grab both the GameSir G8+ for mobile and 8BitDo Ultimate 2 for PC and have a little budget to spare.
It is worth shopping around, too, because the price seems to vary dramatically. Apple lists the Nimbus Cloud £20 higher in the UK than SteelSeries on its own website. And I’ve seen the price drop as low as £64 while writing this piece.

SteelSeries Nimbus Cloud: Design and features
- Cleverly extends from a compact PC controller to a full-width mobile controller grip
- Broad compatibility across platforms
- Nicely sized and positioned rear buttons
Pick up the SteelSeries Nimbus Cloud in its collapsed form, and, apart from a curious split down the middle, you’d be forgiven for thinking it’s a fairly standard Bluetooth gamepad. It has the familiar Xbox-style stick layout, ABXY face buttons, bumpers, triggers, a d-pad, and view/menu buttons.
There’s no center button like an Xbox guide button, though there is a Home button that directs you to your device’s home screen or, on iOS, Apple’s Games app. It’s all pretty standard stuff.
Build quality is alright rather than impressive. I wasn’t blown away by how it felt in my hands but equally there wasn’t any area of particular concern. It’s surprisingly light at just over 250g, which is welcome for a mobile controller with a battery, but that lightness comes with a hollow feeling that doesn’t scream premium.
Nothing rattles or creaks, but it’s no better than a stock Xbox controller and lacks the little premium touches like rubberized or textured grips that you’d expect for $150. SteelSeries says the battery is good for 20 hours of play over Bluetooth and that seems about right based on my testing. There’s passthrough USB-C charging too, but no 3.5mm audio output.
The magic trick is when it engages Transformer mode (an unofficial name I’m giving it). Pull the two halves apart and the Nimbus Cloud unfurls into a telescopic mobile grip, revealing a USB-C connector on the upper right side that plugs directly into your phone.
The mechanism involves multiple overlapping sections that extend, and credit where it’s due, it’s a very clever bit of mechanical design. It just seems to keep going with more and more phone deck appearing from nowhere. It’s satisfying in a fidget-toy sort of way and while using it in PC controller mode I caught myself idly expanding and collapsing it a few times during cutscenes.
Phone compatibility is a mixed bag and unlike other dedicated mobile grips it’s not simply a matter of case on vs case off. I tested with both an iPhone 17 Pro and a POCO X5 Pro. The POCO has a slim, nearly flat profile and fit physically with the stock set of rubber inserts.
By design your phone is seated in the upper half of the grip rather than centrally, though, which leaves it feeling somewhat exposed and prone to knocks. The iPhone 17 Pro was almost a non-starter as with either size of the included rubber inserts the camera bump was too thick to fit neatly.
Even after removing the inserts entirely, which leaves the phone resting against bare hard plastic, it didn’t fit in a way I’d consider usable long term. Beyond worries about it getting scratched to bits, I was concerned about the amount of stress going through the USB-C connector. There’s noticeable movement and wobble with the phone inserted, it never feels square, and one bad bump feels like it could snap the connector off inside your phone’s port.
The rear of the SteelSeries Nimbus Cloud has two programmable buttons that sit in a natural resting position for your middle fingers. I’d call them a hybrid between a paddle and a button and it’s a design that works well ergonomically, requiring just the right amount of force to activate while avoiding accidental clicks.
However, the lack of any official companion app means you can only bind or remap these through iOS’s built-in Game Controller settings. On Android, I couldn’t remap them at all.
For a controller at this price from a brand with the resources of SteelSeries, the absence of a dedicated app for customization is difficult to understand. Competitors like Razer, GameSir, and Backbone all offer robust software companions, and some of those are half the price.
SteelSeries Nimbus Cloud: Performance
- Hall Effect sticks and mechanical face buttons feel great
- Triggers are mushy and lack control
- Connectivity and compatibility is a real mixed bag across platforms
Whether in controller or grip trim, the Hall Effect thumbsticks are the SteelSeries Nimbus Cloud’s strongest performing feature.
They’re quite firm with a relatively fast spring-back and slightly shorter travel than some competitors I’ve tested. That means they’re precise enough for shooters and responsive enough for general gaming, though the smaller range of movement might take some adjustment. Unlike some competitors, there’s no option to swap or adjust the sticks and SteelSeries has played it reasonably safe with a shortish stick height and traditional caps.
The triggers also use Hall Effect sensors, but they’re muddy and I didn’t feel like they consistently recreated their physical movement in game. It’s hard to explain, but where good thumbsticks let you feel dialed in when playing racing games like Forza Horizon 6, on the Nimbus Cloud I felt disconnected when trying to modulate the throttle. This was the same whether I was playing locally on my PC or via cloud gaming on mobile, so wasn’t a Bluetooth latency issue.
The mechanical face buttons are super clicky, tactile, and satisfying to press, as is the d-pad. They’re responsive for general gameplay; however, I noticed the Nimbus Cloud would occasionally miss inputs in situations where I was pressing the same button repeatedly.
This originally cropped up when spam jumping waiting for the Battle Bus in a Fortnite lobby and I was able to confirm it with dedicated testing after getting eliminated. Interestingly, this didn’t seem to be an issue when pressing a combination of buttons so appears to be a debounce problem. The face buttons are pretty quiet but the same can’t be said for the bumpers. It’s nice to see these use mechanical switches, but unlike the face buttons they’re loud and almost sound like a cheap old-fashioned mouse.
When stretched out in mobile grip mode the SteelSeries Nimbus Cloud performs well. On both iOS and Android it was immediately recognized, though the controller itself is a little shy in confirming this for you. The four battery LEDs do briefly light up initially, but I’d like a persistent indicator like you find on rivals.
Both Fortnite and Call of Duty Mobile recognized the controller on launch with no extra config or mapping needed, as did Xbox Cloud Gaming. It all worked nicely and naturally out of the box, which is just as well, because without an app you’d be completely stuck otherwise. I mentioned it before, but the Nimbus Cloud having no companion app feels like a real misstep. Rivals like the GameSir G8+ allow for deep customization like dead zone adjustment and hair trigger modes, both of which are notably absent here on a controller that costs nearly twice as much.
Where things fell apart completely in my testing was when I tried to use the Nimbus Cloud with macOS. SteelSeries lists Mac as a compatible platform, but in my experience it was borderline unusable. It happily connected via Bluetooth without any fuss, but that’s where the joy ended.
In Forza Horizon 6 via Xbox Cloud Gaming I was greeted by the left stick input being inverted and triggers that were mapped to start and select. It turned out the bumpers were acting as triggers instead, and while I attempted to remap through macOS system settings, it didn’t seem to be respected in game. This wasn’t a Forza problem; either, Stardew Valley didn’t even recognize it at all. Steam fared just as badly, albeit in a different way. There it detected the Nimbus Cloud as two separate controllers simultaneously, neither of which worked correctly.
The good news is that I was actually quite impressed with how the SteelSeries Nimbus Cloud performed over Bluetooth (as long as you’re not a Mac main, of course). My iPad Pro immediately recognized the Nimbus Cloud without issue and playing Fortnite natively could easily have been mistaken for a scaled-down console experience.
Connected to my Windows gaming PC I happily spent a couple of hours in Roadcraft and at this slower pace the Nimbus Cloud kept up nicely. I did have to go through the full Steam controller setup procedure, however, something I’ve not needed to do with controllers in the past. Cloud gaming was fine on Windows too, up was up, down was down, and triggers were triggers.

How I tested the SteelSeries Nimbus Cloud
- I spent a few days testing across devices, including an iPhone 17 Pro and POCO X5 Pro, an iPad Pro, a MacBook Air, and a gaming PC
- I played Fortnite and Call of Duty Mobile natively on mobile and iPad, Roadcraft on desktop, and Forza Horizon 6 via Xbox Cloud Gaming.
- I tested it in both collapsed and expanded modes
Over the course of a week I tested the SteelSeries Nimbus Cloud across multiple platforms and game genres. Mobile testing was split between an iPhone 17 Pro and a POCO X5 Pro, covering both iOS and Android in the extended USB-C mode. I played a mix of native mobile games and cloud-streamed titles via Xbox GamePass.
For Bluetooth testing, I paired the Nimbus Cloud with a Windows PC and a MacBook Air, looking at games on Steam and cloud gaming on both platforms. When I noticed potential missed button inputs during regular gameplay, I used a dedicated button testing app to verify.
