[Toy Review] Hismith Premium 4.0 Sex Machine

I’ve wanted to do a Hismith review ever since they first came onto my radar, and I’m delighted to have received the Hismith Premium 4.0 sex machine to test. Now that Mr C&K have taken it for an extensive spin, I can tell you upfront that (spoiler alert) yes, it’s worth the money.

Let’s get into it.

Hismith 4.0: Details & Stats

Official product image: Hismith

The Hismith Premium 4.0 is a modular sex machine made from stainless steel and ABS plastic. It weighs 11.5kg and measures 18.03” x 17.67” x 10.23” when fully assembled.

Yes, this is a hefty piece of kit!

Along with the machine, the kit also contains:

  • The frame (comes in several pieces for assembly at home)
  • A power supply
  • A wired digital display controller
  • A set of anti-skid covers
  • A realistic silicone dildo measuring 8.3″ in total length (5.8″ insertable, 1.6″ maximum width)
  • A waterproof canvas storage and carry case
  • A dust cover
  • 2 Allen wrenches for assembly

The Hismith Premium 4.0 runs on a 100W turbine motor. It has a massive 100 inbuilt speeds, with a maximum speed of 267 strokes per minute (that’s around 4.5 strokes per second!) The stroke length is also adjustable, from 1.3″ up to 5.03″. The included wired remote control has a 2.5″ digital display. You can also use the machine with the Hismith app, if you like.

The machine is highly adjustable, with a full 180° of range.

I received the Hismith Premium 4.0 in black to review, but it’s also available in purple.

Assembly

Everything you need to set up your Hismith Premium 4.0 sex machine is included, so you won’t need any additional tools. (Though you might find a tape measure or ruler handy to ensure the vertical bar is positioned centrally when secured to the horizontal bar.)

We found the instructions clear and the process straightforward.

It’s totally possible to set up the Hismith 4.0 by yourself, but it’s easier with two people. From unboxing the machine to plugging it in and switching it on, the process took me and Mr C&K about 30 minutes. But remember this is a one-time process. You can take your machine apart between every use, of course, but I don’t recommend it unless absolutely essential.

The Kliclok mechanism is secure, and makes it super easy to attach and detach a dildo or other toy. Swapping out your attachments takes literally seconds. It appears to be a proprietary design, so you won’t be able to use toys from other brands with your machine out of the box, but Hismith offers various adapters to make other toys compatible. Hismith also has an extensive catalogue of compatible dildos, masturbators, and anal toys available.

Once your machine is set up, adjusting the angle is easy thanks to quick-release locking mechanisms (no tools required, so you won’t need to break the mood if you need to adjust mid-session.)

Hismith 4.0 Sex Machine Review: In Use

It’s hard to know where to start with all the things I love about the Hismith Premium 4.0.

Hismith 4.0 Premium sex machine

When we took it for a test run, the reason behind the Hismith 4.0’s weight and bulk became apparent. Even on a soft surface (our bed, in this case) it was able to stand on its own and remain in position on all settings. If you’re looking for a truly hands-free sex machine, this is it. I like that I can keep my hands available to touch my partner or hold a vibrator while I’m using the machine.

When I’ve tried cheaper sex machines and thrusting toys, one of the biggest problems has been that they simply… stop mid-use. They’re often no match for the clenching of a vagina (or a butt), particularly at the point of orgasm, causing them to get stuck or just cut out. Absolutely no such issues here. Even on the very slowest setting, the Hismith 4.0 keeps up a steady, smooth, and consistent thrust.

The adjustable stroke length is perhaps one of my favourite features of this machine. I’m someone who doesn’t always enjoy very deep penetration and, even when I do, it requires a lot of warm-up to get there comfortably. Being able to choose a short stroke length and gradually increase means I don’t have to risk getting painfully poked in the cervix.

The adjustable angles are also, of course, excellent. It means you can use the toy in all kinds of positions. Seated, standing, lying down, on your back, doggy style… truly endless possibilities.

These features, combined with an incredible 100 speeds, means you can create exactly the experience you want to have. And, of course, you can change things up as you go or do something different next time, if you like. Speaking of all the speeds: start low and work your way up. For the sake of the review, we tried every single one of the Hismith 4.0’s 100 speeds. Personally, I can’t go any higher than the 50s and still be having fun, but your mileage may vary. The roller wheel on the remote control makes it easy to change speeds rapidly if you need to.

There are also patterns to play with, and (particularly important if you’re using the higher speeds) a quick-stop button that turns the thrusting off immediately.

The included dildo is more or less perfect. While I would have preferred a less realistic aesthetic (the option to choose your own dildo or attachment would be cool!), I otherwise can’t fault it. The size is satisfying but not intimidating. It’s just flexible enough to be comfortable but just rigid enough that it doesn’t fall out or miss during use. And in some positions, the balls stimulate my clit when I have the machine set to a longer thrust length.

Noise-wise, the Hismith 4.0 is also impressive. Nothing of this level of power is going to be silent, but it’s also not obtrusive. And, mercifully, it doesn’t make the horrible screeching/squeaking noise that many thrusting toys give out. (Story time: I was once at a sex club and I heard a noise from across the room that sounded, I kid you not, like a seagull squawking. I looked over and realised the noise was coming from a very squeaky fucking machine.)

Hismith sells a huge range of accessories and add-ons to make its machines more versatile. There are platforms and extenders to increase the height, leg rests, vibrator holders, and more. I appreciate that it comes with a storage case and a dust cover.

More Options with the Hismith App

I’ll be honest: app functionality isn’t really my thing. I try a lot of toy apps as part of this job, but I rarely (read: basically never) use them as part of my actual sex life outside of the testing and reviewing process. We all spend so much time on our phones anyway. I don’t really want to be using it during sex, too.

But if you’re a fan of toy apps, you can get even more functionality out of your Hismith sex machine with the Hismith app. It’s free to download, and allows you to choose a pre-programmed thrust frequency or create your own, hand over control to a partner (including long-distance), connect with other users via chat (and hand over control to them, if you like), and change your machine’s speed with the swipe of a finger.

Hismith 4.0 Sex Machine Review: Verdict

Hismith 4.0 Premium sex machine

I can’t believe I’m telling you a toy that retails for £569/$599 is worth the money, but I am!

If you enjoy penetrative sex and you’re looking for a toy that will do the hard work for you, the Hismith Premium 4.0 is a brilliant investment.

This is an incredibly well-designed and well-made machine. I fully expect it to last for years. The app functionality, the option to add different attachments and accessories, and the exceptional versatility really take this one to the next level.

Great work, Hismith. You’ve converted me. I also invited my lovely metamour to try this machine and, in her words, “it’s raised the bar so much it’s ruined any other sex machine for me!”

[Guest Post] We Cancelled the Threesome and Bought a Sex Machine

Today’s guest post is kindly sponsored by Hismith, manufacturer and retailer of premium sex machines.

My partner and I had been talking about a threesome for six months. It started on a road trip, one of those conversations where you’re tired and honest and the guardrails come down. Neither of us had done it before and we both found the idea electric: bringing someone new into the mix, seeing each other through someone else’s eyes, breaking out of the five-year routine that had started to feel a little too predictable.

But the hypothetical discussions that were fun at midnight felt heavy and a little too real in the light of day. The logistics alone were a nightmare. Coordinating three schedules, managing jealousy, finding someone we both liked—it suddenly felt less like planning great sex and more like executing a corporate merger. Every time we found someone we thought we might be into, the same questions and insecurities arose. Who was more into them? Whose idea even was this, really? 

That’s when it hit us: what we actually wanted wasn’t an extra person in our bedroom. It was just… something new. Something that would shake up our routine without shaking up our relationship. So we tabled the idea of opening up our relationship and started looking at things we could enjoy just the two of us instead. Ultimately, we bought the Hismith 4.0 Premium.

I didn’t expect it to work. Not the machine itself; I’d read enough reviews to feel confident it would perform. What I didn’t expect was how much this new sexual adventure would bring to our relationship. 

You might (reasonably!) wonder why we’d spend nearly $600 on a sex machine instead of choosing something cheaper and less space-intensive, like a dildo or vibrator. But when we started looking at toys together, we realised that what we were looking for wasn’t just power or speed, but a toy to play a specific role. A typical vibrator or dildo still requires someone to hold it, position it, control the rhythm. A sex machine, though, takes this labour out of the equation. My partner could lie next to me, witnessing my pleasure without any physical obligation to perform. The Hismith sex machine enabled us to shift between the roles of active participant and relaxed witness, and that’s what ultimately made the threesome fantasy unnecessary. We didn’t actually want a third person. We just wanted the equivalent of a third pair of hands.

The Specs

The Hismith 4.0 Premium has a stainless steel and ABS plastic body. Its 100W brushless turbine motor can deliver up to 267 strokes per minute, with a stroke length that’s adjustable from 1.3”up to 5.03”. It retails for $599/£599. 

Fully adjustable, the Hismith 4.0 allows you to enjoy various different positions. One One silicone dildo (5.8” insertable length) is included, and the KlicLok system allows you to purchase and use additional attachments if you like. It also comes with a wired digital display controller, a set of antiskid covers, an adaptor, a canvas storage and travel bag, and the various components you’ll need to set it up. 

This machine weighs 11.5kg and measures 18.03” x 17.67” x 10.23” when fully assembled. 

What We Loved About This Hismith Sex Machine

The Hismith 4.0’s KlicLok quick-change system is a breeze to use. I’ve tried machines where swapping out one attachment for another meant sweating over a tiny screw while the whole thing wobbled. With this one, though, it’s as quick and easy as swapping a camera lens. With different types, textures, and sizes of toys available, you might find yourself swapping them more than you think, sometimes mid-session. But because there’s zero friction to doing it, there’s no reason not to. 

The Hismith app also pleasantly surprised me. I’m cynical about smart toys, which are often laggy and frustrating to use. But the Hismith 4.0’s Bluetooth connection was rock solid and responsive, with virtually no delay. 

Noise-wise, this machine definitely makes a noticeable sound, but the level is totally acceptable. The brushless motor hums but doesn’t scream. If your walls are thin, you might want to stick to lower settings late at night or when others are home.

Things to Be Aware Of 

I love this machine, but storage is an issue. This thing pretty much as to live out in the open. Though a large carrying case is included, it’s not a “tuck in the nightstand drawer and forget about it” product. If you have room-mates or nosy visitors, plan your setup accordingly. And if you live in a small apartment and space is at a premium, you might like to consider a mini sex machine instead. 

The Shifts That Surprised Me: What The Hismith 4.0 Sex Machine Did For My Sex Life

The biggest surprise wasn’t the pleasure and orgasms this machine gave–that was expected. No, what surprised me the most was the pressure it lifted.

I’m the type of person who worries about performance during sex. “Is this taking too long?” “Is my rhythm off?” “Are they still enjoying this or do they just wish I’d hurry up and finish already?” With this machine, that anxiety evaporated. There’s nothing to manage because there’s no person on the other end to disappoint. No coordination is required. Just presence. The machine does the labor and all you have to do is feel. If you’ve ever been the partner who worries you can’t last long enough, or the partner who worries they’re asking for too much, you might recognise the relief you feel when you find a solution that works. For us, that solution was a fucking machine. 

The first time we tried the Hismith sex machine, my partner said something I think about a lot. They said: “I finally got to fully relax and just watch you feel good, without carrying the pressure of having to make it all happen.” That’s not something a handheld toy can offer, but it also wouldn’t have been a fair expectation to put on a third person. The machine allows us to go as long as we want and stop when we’re done. 

Is the Hismith 4.0 Sex Machine Worth It?

$600 is a significant investment, and this machine isn’t going to be“impulse purchase” territory for most people. But the build quality is exceptional. And, compared to the emotional cost of a threesome we absolutely were’nt ready for, it was a bargain. 

If you’re looking for something that functions as an extra pair of hands without the pressure, jealousy, or scheduling hell of opening up your relationship, a sex machine can be a fabulous investment. Just maybe skip it if you don’t have the storage space!

5 Things to Consider Before You Buy a Sex Machine

Compared to the various other toy categories I review all the time, such as vibrators, dildos, and strokers, sex machines (AKA fucking machines) are a relatively niche corner of the sex toy market. This is partly due to cost; choosing to buy a sex machine can be a major financial investment, costing hundreds to thousands of dollars. They can also take up a lot of space.

Even so, based on reviews I’ve read, sex machines have an enduring fan base and seem to have grown in popularity and prevalence in recent years.

A sex machine is simply a machine designed to simulate sex with a partner, particularly penetrative vaginal or anal sex. You attach a toy – such as a dildo or masturbator – to the mechanism, and the machine then thrusts back and forth. Many machines have additional features such as an adjustable angle, adjustable speeds, remote control or app-control functionality, programmable settings, space to add an external vibrator such as a wand, and more. Ride-on designs are also popular.

Many people enjoy sex machines because you can enjoy them hands-free and because they can provide a more immersive, lifelike sensation compared to other types of toys.

So if you’re thinking about making the leap, what do you need to know before you buy a sex machine?

Space Concerns

Sex machines vary in size, but even the smaller ones are much bigger than your typical hand-held sex toy. Before you buy a sex machine, always make sure you have the space for the model you’re considering. This means making sure you have a safe and spacious place to set it up and use it, but also that you have somewhere to store it if you’re not going to have it set up permanently.

If you live in a small apartment, need to be discreet, or have limited storage space available, you might want to consider one of the small sex machine models on the market. Take measurements of your space, and triple check before you click the “buy” button. Don’t forget to think about practicalities such as easy access to a power socket to plug your machine into, too.

Budget

How much a sex machine costs varies enormously. The most basic models can cost under $100, while high end sex machines can run into thousands of dollars. Before you start shopping, decide what kind of budget you’re comfortable with. Before you buy one, consider the budget you’re comfortable allocating for a sex machine.

In general, cheaper machines will be more basic and have fewer features. However, they might still suit your needs just fine if you’re on a budget. If you’re looking for extras such as remote or app controls or greater levels of personalisation/adjustability, you can expect to pay more.

Don’t forget to account for dildos or other attachments, lube, positioning aids, travel or storage cases, or whatever other extras you might need as well as the machine itself.

Comfort and Positioning

Learning how to use a sex machine comfortably and pleasurably can take some practice. One thing you’ll need to figure out is the most comfortable and practical positions in which to use it.

Before you buy a sex machine, think about how you will actually use it in practice.

Many people find that it is easiest to use a sex machine while reclining on their back on a bed, or face down in a “doggy style” position. Others prefer to use another surface such as a couch or spanking bench to achieve the desired position. Positioning aids such as sex furniture, sex position wedges, and sex swings can also be a great option, as can add-ons for your machine designed to adjust its height or angle to suit you.

Another aspect of comfort in use is stroke length. This simply means how far back and forth the toy moves when the machine is switched on. A longer stroke length will give you deeper penetration, while a shorter stroke length will give you shallower penetration. Some machines offer adjustable stroke length, while others are fixed at one particular length.

Before You Buy a Sex Machine, Consider Toy Compatibility

Some sex machines come with a dildo (or several) included. Others don’t have toys included and you will need to buy these separately. Sex machine attachments don’t stop at standard dildos, either. You can also get fantasy toys, ejaculating or squirting dildos, anal toys, masturbation sleeves, and much more.

Your sex machine will be compatible with toys using a certain attachment type, and this can vary between manufacturers and machine models. This may mean you won’t be able to use your existing toys with your new sex machine, or you may need to buy an adaptor to enable you to do so. Always check before you buy a sex machine to make sure that your toys are compatible or that you can get toys that will work for you and fit your chosen machine.

Whatever toys you choose, make sure you opt for body-safe materials. 100% silicone is best! Reviews are a great tool in helping you to find the best toys to use with your sex machine.

Aesthetic

You might not care at all what your sex machine looks like. On the other hand, you might care a lot! Perhaps you want a machine that feels like “you”, or something that ties in with the decor of your bedroom, home dungeon, or other playspace. Before you buy a sex machine, consider whether aesthetics matter to you.

Sex machines are available in numerous different designs and colours. So whether you’re looking for sleek black or silver, hot pink, or something more unusual like red, gold or blue, there’s sure to be a machine that suits your preferred aesthetic.
