UEROS Nexus Compact Sex Machine in-depth review
A luxury-deluxe sci-fi fantasy thruster that really nails it.
I love to thrust my insertable toys while I’m using them but it gets tiresome after a while, so the idea of a self-thrusting toy is really appealing to me. The first one I tried — the Lovense Gravity — was good but also has some serious flaws that dissuade me from using it very often. Then the Lovense Vulse self-thrusting egg was a complete failure for me which I unceremoniously thrust into the retirement drawer. So I was really excited when UEROS offered me the chance to try out their top-of-the-line Nexus compact sex machine! It’s a luxury item with a price tag to match and it’s not completely flawless, but it‘s an excellent device overall and might be well worth it if you can afford the splurge. Not to mention how stylish it is!
As always, earning and keeping your trust is genuinely important to me. Since the Nexus is a particularly expensive product that I can earn affiliate commissions on, I want to explicitly acknowledge the financial incentive this creates for me to give it a positive review. I try very hard to be transparent and not let that affect my opinions, but only you get to decide whether I deserve your trust and support.

Product design
UEROS is a new sex toy brand created by UPKO, a purveyor of luxury BDSM gear. Although UEROS only offers three toys at the time of this review, they’re genuinely unique — not something we see very often in the sex toy industry! They aren’t currently creating any whole new categories, but these clearly aren’t just low-effort copies. UEROS is doing some very real design work, and it really shows with the Nexus.
Given that I’m a big-city apartment-dweller, the Nexus’ compact size makes it very appealing compared to a full-sized (and even more expensive) sex machine from brands like Hismith. The Nexus also ships with its own storage case. It’s reasonably sturdy (like a typical thin-sided hard-shell suitcase) and has foam cutouts inside to hold the different parts perfectly in place. I haven’t been using the case much since it was easier to leave the machine assembled while I was testing it frequently for this review, but it will be a great help in keeping the dust away. And doesn’t it just look super cool? I genuinely and unironically love the “MOOD ORGAN” designation.

Main unit and base
I adore the look of this thing. The design screams “premium” despite using plastic. In handheld mode, the main unit looks like a futuristic ray-gun that pounds the “victim” tirelessly. I maaaay have once held it up in a misremembered Charlie’s Angels pose while peeking around a doorway shouting “Freeze!! Dildo Patrol!!” 🤣 The optional base features an adjustable arm which makes solo play much easier while looking like futuristic robotics lab equipment. This can play into various fantasies, whether they be sci-fi or hentai or whatever else floats your steamy boat.

Take notice, though, that the main unit is not waterproof. Much like with the Lovense Gravity, that seems disappointing at first but probably isn’t a big deal since it would be difficult to keep the insertable portion lubed up in the shower. Water-based lube rinses off easily, and silicone-based lube can permanently damage silicone toys. Whenever the main unit needs cleaning, wipe it down using a damp (not soaking wet) washrag.
The base also has a high-quality suction cup with a sliding lever. This design is much more effective than a basic suction cup (like the Lovense Gravity uses) for creating a vacuum during attachment, creating a stronger and more reliable suction effect. Instead of pushing some of the air out by physically pressing the suction cup on a surface, this stronger style of suction cup starts out flat so there’s only minimal air between it and the surface, then the cup’s centre is pulled inward by the lever to create the vacuum. As long as the Nexus suction cup is clean and pressed against a smooth surface, it’s not coming off without significant effort. (Until you move the lever back to the release position, of course!)
The adjustable arm can be repositioned in many different ways. It isn’t perfect, however… the arm’s angle can’t be adjusted and the main unit’s handle prevents the unit from being positioned close to surface it’s mounted on. That’s unfortunate because when I’m on my back, I’d like the attachment to be low and angled upward. But thankfully, the arm provides enough adjustability that I can turn the main body upside down and get it in a position close to what I want. (I’ll talk more about positioning in the “In-use experiences” section below.) The joints are held in place with bolts which can be hand-tightened with the permanently-attached knobs. It works fine, though I wish they’d gone with a fancier spring-loaded option that would be quicker to change.

Finally, the remote control is a well-designed accessory. It magnetically attaches to the base so it’s easier to keep track of (and thus avoid losing it) plus it has its own rechargeable battery that charges from the main unit instead of needing a separate charger or coin-cell battery. The remote makes solo play much easier since I can position the Nexus freely in different positions without concern about reaching the on-body controls.

Attachments
Nexus comes with two attachments: one vibrating and one with rotating beads. These are proprietary for the Nexus and there’s no option for attaching your own dildos via a suction cup or Vac-U-Lock adapter. While that’s a bit limiting, it’s not necessarily a bad thing. I can easily imagine someone connecting a huge girthy dildo and complaining that the motor doesn’t have the torque necessary to drive it. The two included attachments are on the slender side, but this is a good thing for helping avoid motor stalls. There are two pins of slightly different sizes to line up, then just insert the attachment and twist clockwise so it clicks into place.

I’d like to see UEROS offer additional styles in the future. In particular, I’d love to try a body-safe non-silicone attachment that could be used with silicone-based lube for smoother operation. But selling extra niche accessories for what’s already a relatively niche device is unlikely to make good economic sense, so I’m not expecting that. I’m still happy with what’s included.
The attachments are both waterproof for easy cleaning. I was initially worried about grime getting trapped in the vibrating attachment’s crevices, but the silicone flexes allowing for me to easily get some soap in there with a finger. Keeping it clean hasn’t been a problem at all.
Not for anal play
First, the attachments lock into place and release with a slight twisting motion. While it’s unlikely they’d get twisted during use and pop off, it’s certainly possible. If that happened, the motor could potentially push the attachment fully into the rectum and it could get lost inside — a potential medical emergency. Not sexy. Not worth the risk.
Second, the anus tends to grip toys more tightly than vaginal muscles do. Since the Nexus has limited torque, I suspect you’d experience frequent motor stalls using it anally, even with copious amounts of lube. It’s not likely to be a good experience, though I haven’t tried it for myself due to the aforementioned risk and lack of interest.
If you’re interested in anal play, you’ll need to look at the more expensive full-size and high-torque sex machines instead where you can use dildos with a flared base for safety. Nexus is a front-hole-only machine.
Battery power and runtime
Thrusters inherently require a lot more battery power than vibrators, so the roughly one hour runtime is understandable. And being battery-powered makes Nexus a much more useful device since it can be set up in multiple different places without being limited by proximity to an electrical outlet.
I have one major complaint, though… I really wish they’d designed this so that it could optionally be used while plugged in, but UEROS explicitly warns against doing so. Imagine you’re watching a movie on a laptop computer and there’s about 20 minutes left, but the battery runs out and you can’t use the laptop while it’s plugged in. Instead, you have to wait until it’s charged back up before you can finish your movie. How frustrating would that be? Who would want to buy that laptop?
With a toy like Nexus that requires some set-up before use, I’m more likely to be looking for a lengthy pleasure session than a late-night quickie. I hate having to keep an eye on the clock to try to avoid the dreaded auto-shutdown at the most inopportune times.
The Nexus allows you to set a “preferred mode” that you can access by double-clicking the power button. I find this very useful for setting up a “quick cool-down” function that takes the speed down to the lowest setting, analogous to the Afterglow mode many Womanizer toys include. Unfortunately, this reveals another disadvantage of the short battery runtime: Nexus will forget your preferred mode if the battery is depleted. And since I often can’t see the display while using Nexus, I can’t see the low battery warning before it’s too late. As a result, I sometimes need to remember to re-program my “preferred mode” at the start of my session.

In-use experiences
I hadn’t appreciated that a machine like this comes with a bit of a learning curve. During my first session, I initially had problems with the motor stalling. (That is, it couldn’t keep the attachment moving.) I think it was primarily due to the angle I was using it at, though I probably needed more lube also. But once I made some adjustments, I found myself laying on my back muttering obscenities and feeling pretty incredible. For a while, I thought I might even cum without touching my clit at all, something that I don’t think I’ve ever experienced. It didn’t actually happen, but perhaps it might have had I been in a less analytical and more pleasure-seeking mindset!
I also tried using the Nexus in handheld mode. The large handle makes this dramatically easier than it is with the Gravity thruster. It‘s a serious struggle to hold the Gravity in place well enough, but I can easily wrap my fingers around the forward part of Nexus’ handle and keep it relatively (though not perfectly) still. The physics of self-thrusting means the toy will always want to expand in the direction of least resistance, and I can put up a lot more resistance with a lot less effort given the Nexus’ design.
Regular readers of t4toy know that I love to mix’n’match toys. The main body of the Nexus does a great job of staying out of my way, and I’ve been able to use any clitoral toy I wish at the same time: bullets, air-stim toys, even full-size wands. No hassles, no interference. And better yet? The Nexus offers fantastic synergy with my clit toys, sometimes even getting me to orgasm on lower settings than usual.
In short, it’s a toy that causes me to mutter things like “oh god keep fucking my pussy” aloud. Few are the toys that compel me to verbalize in words!
Attachment features
UEROS says the attachment has a 30mm range of travel. That doesn’t sound so impressive once I mentally convert it to 3cm — the same range that the Lovense Gravity offers. Yet it turns out to be enough in this case, especially given the speeds it moves at. The Nexus’ slowest thrusting speed is a touch faster than the Gravity’s highest. So even though I do wish I could get some deeper thrusting, I don’t feel like the 3cm range holds me back. The speed of the pounding makes up for it.
As I alluded to before, the attachments don’t offer much girth. (I wasn’t always a fan of girth though these days I am.) But anything larger than these would probably result in the motor stalling more frequently. While I’d really enjoy a thicker attachment, at least I don’t feel like they’re too small.
Of the two choices, I strongly prefer the vibrating attachment. The motor seems to stall less when using it, perhaps due to its flexibility. With the rotating beads attachment, I can barely feel those rotating beads even when the thrusting motion is completely off. Once the thrusting is turned on, all the beads do for me is create extra noise. That’s my experience, at least… some people might get more out of it than I do, of course. While the vibrating attachment doesn’t offer the same feeling as a dedicated vibrator since it’s being moved in and out so rapidly, it still adds positively to the experience.
Positions and mounting
The motor stalls more easily than I’d like, but that’s a difficult problem for any toy like this to solve. It happens when the device can’t push the attachment forward, either because my pussy is gripping it too tightly or because there’s nowhere left for it to go. While lube helps a lot with the former, the latter is often due at least in part to my positioning. But that’s also the true benefit of the Nexus machine: it’s extremely adaptable and can accommodate a ton of different positions. Doggie, cowgirl, upside down, you name it. Since it’s battery-powered, you aren’t limited by cord length and power outlet locations. Figuring out how to use it without stalling is part of the learning curve.
Sometimes the problem is that I’m too close to the base unit and the attachment is pressed against the end of my vaginal canal. But other times, the angle is off and it’s pressing into the walls instead. It’s not uncomfortable to me at all — the Nexus doesn’t have the torque to press hard enough to cause pain or anything. It’s just that the angle really matters and it sometimes takes me a few tries to get it positioned just right.
One of the most user-friendly positions I’ve found starts with the Nexus attached to the wall, pointed up and a slight bit outward. Then I put my back against the wall and lower myself onto it while I remain standing. This works really well once I find the right height to mount it at so I can lower myself onto the attachment by spreading out my legs, then bring them back together to raise myself slightly if my pussy gets too close to the base and I start stalling the motor.
That said, I do most of my masturbating in bed just before going to sleep, so I needed to find a way to make it work for me there if Nexus was going to be something I use often. My bed’s headboard is covered in fabric and the sides aren’t pushed against a wall, so I thought back to how I mounted Gravity on a hand mirror which I held vertically. With the Nexus, I can instead lay the mirror flat on the bed to use as a suction cup surface. This works quite well and although the toy rocks back and forth some as it thrusts, it generally stays in place without sliding back.
For missionary position use, I initially moved the arm so that it held the main body upside down and as close to the bed and mirror as possible with the attachment angled slightly upward. I liked this position a lot, but found the motor to stall a bit more often than I was willing to put up with. So I tried again the next night, this time with the main body right side up and the attachment pointing slightly downward instead. Then I slid an extra pillow under my ass to make the angle more comfortable. And THIS was exactly what I needed! For me, the motor stalls are minimal in this position and the base stays in place with minimal effort on my part. This has become my go-to technique for nighttime sessions.
Controls and display
The Nexus features a four-button interface. Briefly hold the power button to turn it on or off. The plus and minus buttons control the thrusting setting while the extra button (the icon looks like a waveform) controls each attachment’s extra feature, either the vibration motor or the rotating beads.
The device provides both steady speeds and patterns for both thrusting and vibration/rotation. Thrusting offers steady speeds 1 through 4, then two patterns (settings 5 and 6) before looping back around to the stopped state. Vibration/rotation works the same, except only settings 1 and 2 are steady speeds and the remaining four are patterns before cycling back around. It’s a little awkward that I can’t move both up and down in the vibration/rotation settings like I can in the thrusting settings, but it’s understandable since thrusting is this toy’s main focus. The extra features are just that: extras.
The display maintains the same sci-fi futuristic aesthetic, using an interesting font for the numbers. (The top number is for the thruster, the bottom number for the extra feature.) They can be a little tricky to read, especially if the screen is angled away from me or upside down, but it’s not difficult to figure out. The display also features two indicators on the sides. The left one is a low battery warning, though it also seems to inconsistently turn on when the motor stalls. It’s unclear to me how much battery is left when the warning comes on, as I often can’t actually see the display when I’m using the Nexus.

The indicator on the right side confirms that a “preferred mode” is being saved. By holding the plus and minus buttons, you can save the current setting and rapidly get back to it later by double-clicking the power button. I use this to simulate the “Afterglow mode” that many Womanizer toys offer — it lets me quickly return to the lowest settings so I can continue enjoying it during my orgasm. On the other hand, the motor tends to stall during my orgasms since my pussy is clenching around the attachment, but that’s not the device’s fault. I mean, I guess it actually is since it made me cum, but you get what I mean. 🙂 This mode has one unfortunate caveat, though — Nexus won’t remember the preferred mode after the battery runs out, so I have to remember to set it again when I start my next session.
Nexus also offers two special modes: orgasm and brake. Hold the plus button to temporarily and immediately jump to the fastest thrusting speed, or hold the minus button to temporarily and immediately pause the thrusting. I think it makes a lot of sense to require holding down the plus button, but I wish the braking function were “sticky” when I release the minus button — the main reason I want to pause is to re-apply lube, which would be easier if I weren’t having to keep my thumb pressed on the button. Because of that, I rarely use the braking function and instead just click minus until it gets back to zero. Even so, I applaud UEROS for recognizing the usefulness of such a feature and including it.
It’s unlikely that the device would get powered on accidentally if it’s in the carrying case, but Nexus provides a travel lock feature for extra assurance. Pressing the power button in this mode helpfully shows a padlock on the display screen. Toggle the travel lock by holding the power and vibration buttons while Nexus is powered off. Holding these buttons while the Nexus is powered on, however, instead turns the light rings on the main body on or off for the current session. While I love how they compliment the device‘s appearance, I usually masturbate in dim lighting and really appreciate the ability to turn them off.
One little oddity about the remote control: it has its own independent power state. If the light on the remote doesn’t illuminate when you press a button, hold down its power button to turn it on. Holding down the power button to turn the remote off will also turn off the main device if it’s powered on.
Verdict
The Nexus is an excellent machine, but I have to think hard about whether it’s worth nearly US $300. It occupies a position in the market between basic thrusting toys and large full-on sex machines, and I haven’t had an opportunity to try the latter yet. But instead of thinking of the Nexus as probably a step down from that, what if I instead look at it as bringing a lot of what’s good about sex machines to a space-saving form factor? From that perspective, the Nexus is easy to recommend if your budget allows — it’s far better, and many times easier to use, than the Lovense Gravity in my opinion.
If you aren’t space-limited, however, then the big question becomes whether you’d be better off putting your money toward a more expensive full-on sex machine instead. And unfortunately, I just don’t have the firsthand experience needed to compare them. It’s obvious to me that the larger machines generally have more torque and run on mains power for practically-infinite runtime, but I imagine they have their own flaws too.
The Nexus’ only serious flaw in my view is the short battery runtime combined with the inability to run the machine from mains power. If you can live with that limitation and if you aren’t seeking anal play, then the Nexus may be just right for your needs. However, I’d also like to see UEROS stand behind their product with a longer warranty than one year — while that’s a very common period for general consumer electronics in this price range, many of their peers in the premium sex toy industry offer longer coverage.
For those reasons, I’ve decided to make the UEROS Nexus sex machine a “provisional” Top Pick. I’ll re-evaluate this decision in the future if I get to try additional thrusters and sex machines, but for now the bottom line is this: I spent my own money on the Lovense Gravity, but I wish I’d spent it on this instead.
Phew. That was a long review, but I had a ton to say about it. Thank you to UEROS for offering me the opportunity to test this out and share my thoughts with all of you! …and now I finally get to enjoy using it without stopping to take notes every few minutes! 🤣
