If there’s one thing we can say about sextech, it’s how grown-up it’s become in recent years. Nowadays, these devices are cleverer than ever – they connect to apps, sync to interactive adult content (including VR in some cases), and can even be controlled remotely by someone else, which can be either hot or deeply cursed, depending on your mood.
Two of the most talked-about options in this space are the Kiiroo Keon and the Autoblow AI Ultra, the latter of which we already pitted against its predecessor in our Autoblow AI+ vs AI Ultra comparison, where cheap materials undercut the Ultra’s price point despite it winning on performance. These devices are similar in the sense that both are designed to offer automated stroking (or should I say, blowing) motion and both lean heavily on synced content to make the experience feel more “real”.
However, each machine approaches this idea very differently. The Keon is essentially an automated stroker system built around Kiiroo’s FeelConnect ecosystem and is battery powered. The AI Ultra is Autoblow’s current flagship, packing video sync, downloadable routines and a more “all-in-one machine” vibe but it needs to be plugged in.
After months of testing both, I’ve pulled together all the key details and real-world quirks to work out what each device is actually like – and which one makes the most sense to splurge on, if you’re in the market for one.
Please note: Since we tend to test toys for months, where possible, a new Keon model is already on sale. Our next comparison will be the Kiiroo Keon 2 vs Keon.
Why use an interactive stroker?
If you’ve only ever used a manual sleeve, the big jump here isn’t just how it moves for you – it’s that the motion can be controlled, repeatable and synced. Interactive strokers are aimed at people who want something more immersive than standard up-and-down friction, and ideally something that pairs stimulation with what you’re watching on screen (or what a partner is controlling).
In the best-case scenario, synced content creates a stronger mind-body link. You’re seeing a movement, and the device responds in time with it. That can feel more involving than just watching a video while using a basic stroker. There’s also the convenience factor, like when you’re not relying on your hand, you can focus more on positioning and comfort – or even just be lazier about it.
Of course, none of this guarantees it’ll feel like the real thing (will it ever?). Often times, many interactive toys nail intensity but feel robotic, while others feel physically great but the syncing is a faff. The Keon and AI Ultra both try to solve that problem – just with very different priorities.
Design: Substance over style
Let’s start with the bad news. Neither of these machines looks particularly premium for the money. The AI Ultra, in particular, is a fairly large device with a plastic-heavy build. It’s practical, it’s easy to wipe clean and the buttons are straightforward, but aesthetically it still has a very white-plastic-appliance energy about it. For the money being asked, it’s fair to expect a bit more polish for the money. Compared to devices like Kiiroo’s higher-end ecosystem products (or even just the general slickness of modern sextech), the AI Ultra feels a touch utilitarian.
The Kiiroo Keon isn’t exactly a looker either, but it’s way more sleek-looking than the AI Ultra, at least. It’s basically a stroking machine chassis with a sleeve system mounted inside, and it’s still big and heavy. Dimensions put it at 220 x 130 x 146 mm, and the weight is 1.1 kg without the stroker – rising to 1.9 kg once you add the Feel Stroker in. That’s a lot for something you may end up holding at awkward angles. The upside is that Kiiroo did improve the layout versus older designs: Controls are placed along the sides rather than awkwardly on the front, making in-session adjustments much easier and more ergonomic in my opinion.
Where the Keon wins points is that the stroker can be used manually on its own, which sounds like a small thing until you remember how many tech-driven toys become useless the second the battery dies or the app misbehaves. Kiiroo’s RealFeel stroker is also described as extremely Fleshlight-like, sporting that familiar tube format, a vacuum cap to adjust suction and a soft-but-structured internal sleeve with bumps and nodules for sensation.
The AI Ultra’s sleeve system, meanwhile, is geared toward Autoblow’s own ecosystem. The Ultra’s “full-shaft gripping” concept is basically central to the product. It’s not modular in that you can swap the tubes and customize it – it’s very much a dedicated machine that expects you to use it as intended.
Both are big, plastic and unapologetically bedside devices. But the Keon’s physical design feels like a refined successor to an existing format, while the AI Ultra feels like a purpose-built machine that prioritizes function and features over any sense of luxury.
Features: How do they compare?
On paper, the AI Ultra looks like the more feature-packed product. It’s a mains-powered unit with built-in patterns and the option to expand via online features. You get a wide stroke range, a library of downloadable routines, and a strong push around video syncing. It’s designed to give you variety without needing external add-ons, and it’s obvious it wants to be the one device you buy and build a routine around.
In practice, the standout feature is the video sync angle. When it works well, syncing movement to content can be genuinely immersive, and Autoblow has leaned hard into that with the AI Ultra. You also get the comfort of consistent power because it plugs into the wall, so you’re not watching a battery indicator or dealing with fading performance as the charge drops.
The Keon takes a different approach. It’s not trying to be a self-contained pleasure machine. It’s trying to be the best stroking engine in Kiiroo’s ecosystem. In manual mode, it’s basically speed and stroke length, which is fine but not exciting. The point is what happens when you connect it to FeelConnect and start using interactive content, VR experiences or connected control.
Battery power is a big feature here, too. Being able to use it without being tethered to a wall changes where and how you can use it. The trade-off is that the battery life varies depending on settings. For example, full-stroke, full-speed sessions drain it faster. Still, for me, the freedom was worth it.
That said, Kiiroo’s app situation needs patience. You have to use FeelConnect 3.0, and the naming can be confusing because older versions still exist. Once I had the right app, connection was generally fine, but it’s the sort of setup hurdle that can kill the mood the first time you use it.
The other big feature win for Keon is future potential. Kiiroo’s ecosystem is built around interactive content and compatibility, and even if not every platform is perfect, it’s a broader playground than a single-brand library approach.
To sum up, the AI Ultra is the feature-stacked all-in-one, while the Keon is the flexible system that makes more sense if you actually care about interactive content beyond what one brand serves up.
Performance: Which feels better, more real and easier to live with?
This is the section where I fully expected the AI Ultra to walk it, simply because video sync is such an easy headline win. And to be fair, when everything’s set up properly, it can be seriously involving. The motion is strong, the grip can feel properly intense and syncing stimulation to what you’re watching genuinely does something to your brain that standard up-and-down stroking doesn’t. If you’re chasing immersion and you like your sessions guided by content, the Ultra absolutely has moments where it feels a step ahead.
But once that initial novelty wore off, I found myself reaching for the Keon more often, and it came down to one thing: It felt better in a more basic, physical sense.
A lot of that is down to the RealFeel stroker. It’s Fleshlight-like in the ways that matter: soft but structured, with internal texture that adds sensation beyond plain friction. The vacuum cap also makes a big difference. When you get the suction dialed in, it creates a more natural, grippy feel that makes the stroking motion feel less repetitive and a bit more believable. It’s still a machine, but even straight out of the gate, the sensation is spot on.
The Keon can also go hard when you want it to. It has the speed to keep up with fast scenes and the punch to feel satisfying, but it’s also good at slower, shorter strokes if you take the time to find the right combination. As with most automated strokers in this category, the downside is the noise. At higher speeds, the Keon can sound like a busy bit of machinery, and there’s a rattle from how the stroker sits in the unit. It didn’t ruin the experience for me, but it’s not discreet, and if you’re using it somewhere you need to be quiet, it’s not an ideal option.
The AI Ultra is a different story. It’s powerful, but it’s also fussier. It needs plenty of lube, and positioning matters more than you might expect. When it’s lined up properly, it can feel immersive and intense – especially with synced content – but when it isn’t, it can feel like you’re wrestling the device to get the right angle, which can pull you out of the moment a little.
Noise-wise, the AI Ultra isn’t silent either. It’s less rattly than the Keon, but there’s still plenty of motor sound. Neither of these is a stealth device, so I wouldn’t buy either expecting discreet use.
Where the AI Ultra loses ground over time is in how the sensations feel across repeated sessions. The syncing is impressive, but I found it could feel more robotic, like it’s executing a program rather than delivering something naturally varied. It gets you there, no question, but it didn’t have the same consistently satisfying physical feel as the Keon.
The Keon, on the other hand, just fits into more routines. Sometimes I wanted synced content, sometimes I didn’t. Sometimes I wanted to use the stroker manually and skip the app entirely. The Keon lets you do that. The AI Ultra feels like more of a commitment every time, mainly because it’s bigger, plugged in and more particular about setup.
As for which feels most like a genuine blowjob, neither fully nails it, and anyone promising that is overselling, in my opinion. The AI Ultra’s video sync does help create a stronger illusion, but the Keon’s sleeve feel and suction tuning gave me the more believable physical experience overall.
Which is worth buying?
Costing roughly $228 (£186) at the time of writing for the Kiiroo Keon (bundled with the RealFeel stroker), versus a similar asking price for the Autoblow AI Ultra of $299.95 (£199), you’re not exactly choosing between cheap or expensive. You’re choosing between two premium-ish devices that justify themselves in different ways.
If you want battery-powered freedom, a stroker you can still use manually and you’re specifically interested in interactive ecosystems (such as VR, compatible sites, connected experiences), the Kiiroo Keon makes a strong case for your dosh. Just as long as you’re willing to accept some fiddly app/platform quirks and a bit of rattle at higher speeds.
However, if you want a more self-contained, consistently powered flagship with a major emphasis on video sync, downloadable routines and straightforward on-device control, the Autoblow AI Ultra is the more compelling option. Even if it does suffer from the classic sextech sin of looking a bit plasticky for the price.
Final verdict: And the winner is…
Both of these devices are good at what they do, and each one has the ability to deliver genuinely impressive sessions once you’ve learned their quirks. The AI Ultra is the more obvious choice if you want an all-in-one machine with built-in variety and a strong focus on video sync. It’s a powerful, immersive machine in most circumstances, and it removes battery anxiety by staying plugged in.
But if you want the device that feels like the better-made, better-to-live-with machine, the Kiiroo Keon is the one I’d opt for. As you can probably tell by what I’ve said so far, it’s by no means perfect. The app setup can be annoying at first, and the rattling at high speeds can be a real buzz killer. The fact that the stroker can disengage if you start fiddling mid-session can also be infuriating, but – despite all that – it consistently delivered the better sensation for me. Plus, its modular sleeve format makes it far more versatile long term, if you ask me.
Overall winner: Kiiroo Keon
If you want the device that feels nicest to own and delivers the most consistently satisfying sessions, Keon takes it. The AI Ultra is still a strong option if video sync is your top priority, but as an all-round interactive stroker you’ll actually keep coming back to, the Keon earned its spot on my shelf.
