Hismith Premium 4.0 Sex Machine Review

Let’s talk about doing nothing. Well, not nothing exactly, but close.

Sometimes I just want to get fucked without doing half the work myself. Not lazy, exactly. Just realistic about what my arms and hips are willing to commit to on a random Tuesday night. I’d been daydreaming about a proper sex machine.

Something powerful enough to handle the thrusting so I could actually focus on how it felt instead of making it happen. And not just solo, something that would work when Luka and I wanted to play together too.

The Hismith Premium 4.0 turned out to be a really good way to explore all of that.

How we tested the Hismith Sex Machine?

I ran it through several solo sessions trying different positions and the full range of speeds and modes. Then Luka and I used it together. We tested it on the bed, on the floor, with me giving him oral while it thrust into me, and during double penetration. I tried both the wired remote and the app.

Hismith Sex Machine review in short

Things we like about Hismith Sex Machine

Powerful and consistent thrusting that feels like getting properly fucked. The KlicLok system makes swapping attachments quick and secure. Lots of positional flexibility thanks to the adjustable legs. Works well solo and even better with a partner. Huge range of extra dildos and attachments available.

Things we disliked about Hismith Sex Machine

It is loud, especially at higher speed (though that comes with the territory for something this powerful.) Needs a firm surface to run at full power without shaking. Assembly takes a few minutes if you cannot leave it set up. The top speed is seriously fast and not for every session.

Key takeaway from Hismith Sex Machine review

This machine is powerful, well-made, and delivers real thrusting power, stays locked in place, and the modularity means you can keep expanding what you do with it. It is not discreet or quiet, but if you have the space it is genuinely fun and versatile for both solo and partnered play.

Hismith Sex Machine box contents and unboxing

The Premium 4.0 arrives in a large box, and inside that is a canvas bag holding everything, with Styrofoam keeping the parts protected. The bag isn’t just for shipping either, it works as storage afterwards, which is useful for something this size. There’s also a separate dust cover to keep over the machine when it’s put away.

Inside you get the main machine, the wired controller with the digital display, six antiskid covers, two support T-rods, the power adapter, an M2 and an M5 Allen wrench, the dust cover, and the canvas bag itself. It also comes with one Hismith silicone dildo with the KlicLok base, which I’ll get into more below.

Hismith Sex Machine size, weight and material

The Premium 4.0 is a serious piece of equipment. It weighs 25 lb (11.5 kg), and while that’s heavy, it’s not awkward to move when you need to reposition it.

The build is sturdy and good quality, made from stainless steel and ABS plastic, with no wobble.. Standing, it’s around 18 inches (46 cm) high, and the machine body itself is around 18 inches (46 cm) long and 12 inches (30 cm) wide.

The arm section where the attachment mounts runs about 12 inches (30 cm). Each of the two legs has its own set of locks for adjusting height, and because they work independently, you can set one leg higher than the other to change the angle of the thrust.

How well it stays planted comes down to the surface. On the floor it doesn’t shift at all. On a table or a soft bed it holds position but shakes at higher speeds, and a firmer surface handles that much better.

The included dildo is soft silicone with a realistic shape, measuring 8 inches (20 cm) in total length, with 6 inches (15 cm) insertable and 1.5 inches (3.8 cm) wide. It clicks into the KlicLok base super easily and stays locked no matter how hard or fast the machine runs.

To release it, you pull down part of the lock and it comes off. It never releases on its own during use.

The wired controller measures 4.5 inches (11.4 cm) long and 3.75 inches (9.5 cm) wide, and it sits comfortably in the hand.

Hismith Sex Machine features

Controlling the machine

The Premium 4.0 can be controlled two ways: the wired controller, or the Hismith app on your phone.

The controller has an LCD screen, a wheel for adjusting speed, and a button that cycles through 8 preset modes. The cord is long enough to hold it yourself while the machine runs, or to hand off to a partner so they can take over.

The two work as an either/or. You’re either running a set speed, holding one steady pace, or you’re in one of the modes, which vary the tempo for you, running slower then faster in a rhythm rather than staying constant.

I found myself reaching for the modes more, since having the tempo change on its own felt better than sitting on one speed.

The stroke itself is adjustable too, from just over an inch up to around 5 inches, and the speed tops out fast. The very top end hits 267 strokes per minute, which is genuinely more than I needed most of the time, but it’s there if you want it.

The Hismith app

Connecting to the app is easy. Bluetooth finds the machine instantly. Once you’re in, there are four modes: solo play, remote play, mode play, and group play.

Mode play is where it really shines. It comes loaded with presets, including ones that imitate the rhythms of real sex and anal sex, and it’s nice to just pick one and let go rather than managing the controls yourself.

Mode play also lets you build and save your own pattern if none of the presets are quite right.

Remote play lets you invite a partner into the app so they can control the machine from anywhere, which makes it a strong option for long distance.

Group play creates a room others can join, though that’s one we haven’t tried.

KlicLok and attachments

The machine uses Hismith’s KlicLok connector system, which is what makes swapping attachments so quick and secure. Everything clicks on and off without tools, and once it’s on, it stays put.

The machine comes with one dildo, but the bigger point is how much you can add to it. There’s a range of extra attachments available to buy, including dildos in different sizes and styles, masturbator cups for penis owners, and various adapters that expand what the machine can do.

Our experience using Hismith Sex Machine

Using Hismith Sex Machine Alone

For the solo sessions I wanted to see how easy it was to use and how quickly I could switch positions. I started on my back on the bed with the machine lowered all the way down.

Once I had the dildo lubed up and lined up, it slid into my pussy smoothly and the thrusting started deep and steady. It felt incredibly intense having something fuck me at a consistent rhythm while I just lay there with my legs open. I could play with my clit at the same time and it built up fast.

Switching to doggy was quick. I raised the legs, got on all fours, and let it pound me from behind. The deeper stroke felt amazing and the consistent pace made me come hard the first time I tried it.

I also put the machine on a low coffee table and took it standing up, bent over. That angle hit different and felt dirtier, almost like someone was fucking me while I was trying to stay quiet.

The modes that vary the tempo (slow and teasing for a few seconds, then suddenly faster and harder) were my favorite. At the top speed it gets almost punishingly fast. I loved it for shorter bursts, but my pussy needed a break after a while.

Using Hismith Sex Machine Together

First Luka took the remote and played with the modes while the machine fucked my pussy. He’d slow it down when I was getting close, then crank it up again just to tease me. Handing that control over to him while I was on my back with my legs spread felt surprisingly hot.

Then we moved the machine to the floor. I got on my knees in front of Luka and started sucking his cock while the machine thrust into me from behind.

Being completely hands-free meant I could focus on taking him deep in my throat without losing the rhythm. The combination of his cock in my mouth and the machine steadily fucking me made me come with him still in my throat.

We also tried double penetration. I climbed on top of Luka so his cock was buried in my pussy, then we positioned the machine behind me for my ass. The adjustable legs made lining it up easier than I expected.

Once both holes were full it was overwhelming in the best way. The machine did most of the hard work so I could just rock between them. Luka said watching me take both at once was one of the hottest things he’s seen me do.

Is the Hismith Sex Machine a loud toy?

It’s not quiet. There’s no getting around that, but with a machine this powerful I didn’t expect it to be, and honestly it can’t really be. The motor makes itself known, more so the faster it goes. For a machine doing this much work, though, the noise felt about right rather than excessive.

How to clean a Hismith Sex Machine?

The dildo cleans like any silicone toy, warm water and mild soap, then left to air dry.

The machine body isn’t waterproof and shouldn’t be submerged, so it just gets wiped down with a damp cloth to clear any residue.

One thing that sets a machine apart from a regular toy is the moving parts. It’s worth keeping them maintained so everything keeps running smoothly over time, which is a quick, occasional bit of upkeep rather than something you deal with every session.

And when it comes to lube during use, stick to water based, since oil based lube breaks down silicone over time.

Special considerations when using Hismith Sex Machine?

At 25 lb (11.5 kg), this is a heavy piece of equipment, and it takes some assembly each time if you don’t have space to leave it set up. Getting it into position and putting it together involves a fair bit of lifting and handling, so anyone with limited strength, mobility, or joint pain may find the setup demanding, or may need a hand with it.

The top speed is genuinely fast, and the thrusting is powerful. Starting slow and working up is the sensible approach, especially the first few times, and the adjustable stroke length helps here since you can keep the depth shallow while you get used to it.

Water based lube is a good idea for comfort given the machine keeps going at a steady pace without stopping the way a person would.

On the accessibility side, the adjustability is a real plus. Because the height and angle can be set to whatever works for your body, and because you can control everything from the wired remote or the app without having to reach the machine itself, it’s easier to tailor to different needs than a lot of fixed setups.

The app control in particular means you can adjust things without moving, or have a partner do it for you.

Final words

The Hismith Premium 4.0 turned out to be exactly the kind of machine I hoped it would be – strong, adjustable, and expandable.

It works well for lazy solo nights when I just want to lie back and take it, and it’s even better when Luka and I use it together.

Setup takes a few minutes and it’s definitely not discreet, but the payoff is worth it.

We don’t have a dedicated space for it, so putting it together is part of the deal every time. Instead of letting that kill the mood, we started making a date of it.

The machine gets set up in advance, and by the time everything’s ready, the waiting has done half the work and we’re both worked up before it’s even switched on.

I can already tell we’re going to get a lot more use out of this one.
