Hismith Premium 4.0 sex machine review: best in class?

Hismith’s Premium 4.0 fuck machine thrusts up to 267 strokes per minute, from soft grind­ing to full-​wall bullying.

It holds up against my goril­la grip coochie clench­es, and syncs its speed with the vol­ume of my moans — all while the machine itself stays qui­et, leav­ing my eardrums to enjoy audio erotica.

Bronze Age war­lord and king Agamemnon could con­jure cunt and booty­hole on com­mand, but could he thrust like the Hismith sex machine's adjustable stroke length?

1.2–5.0 inch­es, indef­i­nite­ly, with such con­sis­tent fervor?

Could he, lit­er­al roy­al­ty, expe­ri­ence the extent of erot­ic ecsta­sy I do as a mere mer­chant, scribe, and witch in the Common Era?

Could he even fath­om a woman reach­ing such hedo­nis­tic heights, end­less orgasms, Eros strikes entire­ly sev­ered from repro­duc­tion and polit­i­cal practicalities?

No. No, he could not.

Could any­one from that era imag­ine end­less flesh-​like phal­lus­es of all these sizes and shapes, some with slid­ing skin, to pop on and off the Hismith Vac-​U-​Lock con­nec­tor? Maybe some per­verts played with pre­his­toric poly­mers, but not like the body-​safe mate­ri­als we have today.

Hismith goes beyond the Velvet Thruster's self-​contained bar­rel cam mech­a­nism and into high-​end adjusta­bil­i­ty and angling in a bulki­er but easy-​to-​set-​up unit. As far as ready-​made sex machines go, Hismith’s Premium 4.0 is one of the best in its size class.

Borderline tor­tur­ous orgas­mic over­whelm. It jolts my G‑spot and my A‑spot in one go. 25–35% speed here is plenty.

I’m so grate­ful to be alive at the same time as the Hismith Premium 4.0 fuck machine — and all the attach­ments to mix and match with it, and clean run­ning water, and plen­ti­ful puri­fied lube.

Perks of the Hismith Vac-U-Lock adapter

If you've been con­sum­ing my con­tent for a while, you prob­a­bly didn't come this far to only come this far.

In our day and age, the knowl­edge work­ers have con­jured Hephaestus for the secrets of forg­ing sand into sil­i­cone — a sub­stance sup­ple like skin that is some­how san­i­tized like a met­al. Fine ridges, big bumps, juicy glan­des, hel­la cor­pus spon­gio­sum on the under­side of the shaft? The options are endless.

Vac-​U-​Lock vs. KlikLock vs. suction cup base

Get the Vac-​U-​Lock attach­ment for your Hismith sex machine so that you can attach arti­sanal dil­dos with com­pat­i­ble base ports from the likes of Dee's Big Daddies, Uberrime, Hankey's Toys, Uncover Creations, b‑Vibe, and more. Just do it and thank me later.

Vac-​U-​Lock dil­dos come in such a wide range of shapes and sizes, and from mass-​manufactured firm phal­lus­es to slid­ing skin to exot­ic extrater­res­tri­al and eldritch enti­ties.

Yes, Hismith has some in-​house KlicLok dil­dos, includ­ing sup­ple dual-​density mod­els, but by the time you're shop­ping for a pre­mi­um fuck­ing machine, you prob­a­bly have strong pref­er­ences for your phalluses.

Yes, you can get the dock­ing plate for your suc­tion cup base dil­dos — I under­stand that more peo­ple have suc­tion cup base dil­dos than Vac-​U-​Lock base dil­dos, so porque no los dos?

If your favorite thrust­ing dil­do is flat-​based, you can use that with a suc­tion cup adapter, though it can get finicky with firmer toys and cer­tain speeds and angles.

Personally, I favor the Vac-​U-​Lock con­nec­tion for its ver­sa­til­i­ty, sta­bil­i­ty, and sim­ply fun with angling.

That brings me to what I love about the stroke length range.

Hismith Premium 4.0 sex machine stroke length & positioning

I CAN USE A LONG, FLEXIBLE (say, Shore 0030) DILDO TO BEND AND BUMP MY CLITORIS WITH EACH ANGLED THRUST WHILE MY CERVIX IS SERVICED with the short stroke length option! In this way, the 65% speed set­ting is my sweet spot.

OR I CAN SAVOR THE LONGER DONG-​BONKING, slid­ing six inch­es back and forth, push­ing me into bor­der­line tor­tur­ous orgas­mic over­whelm. It jolts my G‑spot and my A‑spot in one go. 25–35% speed here is plenty.

When lying down in mis­sion­ary with the Hismith Premium sex machine, I can angle my hips back for for­ni­cal fuck­ing, slid­ing in front of or behind my cervix for vig­or along my vagus nerve. Or I can tilt my hips for­ward or put a wedge cush­ion under me for max­i­mum clob­ber­ing of the CUV com­plex (also known as the G‑spot).

You can adjust it to do doggy-​style, but that's not my favorite way to use it. In mis­sion­ary with a flex­i­ble dil­do, I can lean for­ward, let the toy bend, and adjust the stroke length.

I love the single-​inch finess­ing for pure plea­sure. I love the longer, stronger prop­er pound­ing for mak­ing myself a masochis­tic mess. Oh, gosh, the slip­ping and slid­ing are gen­er­ous, but it's the forced orgasms that hurt so good.

I could see myself using every stroke length in between, depend­ing on which dil­do I con­nect to it.

Do I need 267 strokes per minute? Not with the longer thrust length, I don't — 25% to 65% is per­fect for me.

Hismith Premium 4.0 sex machine intensity

As for for­ti­tude? Yup, it keeps going and going.

The Hismith Premium sex machine thrusts up to 5 strokes per sec­ond, with a torque of about 300N. In plain English: it can go real­ly fuck­ing fast.

It might stall when specif­i­cal­ly com­bin­ing low speed and high stroke length, but there's such a wide range that slow­ing down a lit­tle at the upper end isn't a big deal.

Do I need 267 strokes per minute? Not with the longer thrust length, I don't — 25% to 65% is per­fect for me. And gen­er­al­ly, there’s going to be a bal­ance between stroke length vs. speed and torque with any fuck machine.

If you're famil­iar with my work, you know my ten­den­cy to clench and eject a toy when I orgasm. I've cum a lot with the Hismith Premium and my beloved Big Daddy Dante XL, but assum­ing I've cor­rect­ly set up and posi­tioned it, I've only seen stars with the insertable portion.

With the Hismith sex machine, the sound-​activated set­ting on my phone sens­es my sighs and screams, then con­verts them to kinet­ic cunt-​punt. I cum. The thruster fucks faster. I scream and whim­per some more. It not only stays in me, but keeps going and going, even hard­er than before.

Can you use a Hismith sex machine with a huge dragon dildo?

If you’re look­ing for a sex machine to use with huge and knot­ted toys — which aren’t my type, but I get the appeal — you might want to look at more pow­er­ful mod­els to main­tain speed and stroke length. Otherwise, you might find your­self using short­er strokes or going slow­er than you would 100% ide­al­ly like.

For me, it’s enough, but drag­on dong fanat­ics should keep in mind the tradeoff.

Could I use a big­ger, tru­ly behe­moth mon­ster dong with the Hismith Premium 4.0? Yes. But also, I'd rather ride one to lever­age my body weight, and it doesn't take much move­ment for mag­nif­i­cent impact.

Tl;dr of how I personally feel about the HIsmith Premium

Adjust the thrust­ing and angling to savor every bump and ridge. Twist your hips. Let some­one else cuff you and take con­trol. It all feels so fuck­ing good. The strength, the ver­sa­til­i­ty, the rel­a­tive­ly qui­et con­trap­tion con­fig­u­ra­tion. I can't say enough good things about the Hismith Premium 4.0 fuck machine!

Granted, I had my AirPods and a tryquinn​.com audio. There's some mechan­i­cal whirring, but very slight.

How loud is a Hismith Premium sex machine?

While I gen­er­al­ly think "whisper-​quiet" is a mar­ket­ing buzz­word, the Hismith Premium sex machine is indeed quite quiet.

In my (erot­ic) voice record­ing with the Duo-​Play 2.0, you could bare­ly hear the thrust­ing mech­a­nism in the back­ground. It's a dif­fer­ent Hismith mod­el that's meant for part­ner play but actu­al­ly less sta­ble and makes mar­gin­al­ly more sound.

And here's a video of it. (Just to demon­strate the motion. I know some of you want to see me using it, but the focus here is my enjoy­ment, mmkay?)

I had my Hismith Premium 4.0 propped up against a hotel room wall and didn't wor­ry about what guests in the next room would think.

If you live with oth­er peo­ple, yeah, it's hard­er to be visu­al­ly dis­creet with a full-​sized fuck­ing machine, but its noise lev­el is noth­ing com­pared to the com­pact reciprocating-​saw-​like mod­els.

Play some white noise. Assemble and dis­as­sem­ble this fuck machine in about ten min­utes. It's fine.

Hismith Bluetooth app control

We can use the cord­ed remote or a hand­held slab made of sand, met­al, and light to con­trol the machine with our dig­its from a distance.

Translated: yes, Hismith sex machines have a Bluetooth app con­trol option.

Here's what the Hismith app can do, at a glance:

• Simple speed slider
• Ambient sound activation
• Thrusting pat­terns gallery
• Long-​range part­ner play
• Set a max­i­mum speed

And the sound-​activated set­ting is a lot of fun for teas­ing, then swap­ping to the sim­ple speed slid­er to fine-​tune the frequency.

I wish I had got­ten a Hismith Premium sex machine sooner.

Hismith sex machine pros and cons

Are there any downsides?

Yes, but they're quite min­i­mal in exchange for every­thing I get with the Hismith Premium 4.0.

• You can't change stroke length tru­ly on the fly, but it's easy enough — pause it, turn the knob, move the lever arm to your desired posi­tion, and turn it back on.
• It gets mild­ly annoy­ing to dis­con­nect a cord when adjust­ing the angle, since the platform's clamp opens in the same area as the port and plug. You might have to unplug and re-​plug and clip and unclip a few times to get the height and tilt just the way you want it.
• It's not the heav­i­est sex machine and can shift if you BACK DAT ASS UP on it. Just make sure to prop it up against a wall or heavy piece of fur­ni­ture — no big deal — or get some hard­ware to mount it.
• The T‑braces can slide a lit­tle bit — also not the best, but it doesn't affect usage much for me.

Overall, there's some iner­tia to set­ting up, but not much more than oth­er sex machines I've tried.

I love plen­ty of big things and lit­tle things about the Hismith Premium 4.0 — the stroke length, qui­et thrust­ing, Bluetooth app, can­vas bag, and stur­dy foam cush­ion­ing make it all worth it. (Yessss!!!! Ease of car­ry! No Styrofoam pack­ag­ing bullshit!)

Setting yourself up for prime pleasure

While we're dis­cussing the prac­ti­cal­i­ties, here are some sug­ges­tions for set­up, so you have a peace­ful expe­ri­ence where you're not dis­rupt­ing pre­cious thrust time to — oh no! — take the toy out and get up to get lube.

Perhaps the most impor­tant detail is get­ting the depth right:

1. Turn on a real­ly slow set­ting and halt the machine once the rod sticks out as far for­ward as it can.
2. While it's paused, posi­tion it at the max­i­mum depth inside you.
3. Then, turn on the speed back on.

That way, you don't unex­pect­ed­ly ram your­self deep­er than you were expecting.

Beyond that, some small­er adjust­ments include the following.

• Be mind­ful to have some­thing sta­ble behind your fuck machine — or use hard­ware to mount it, if that's your thing.
• Maybe get a sticky mat to reduce sliding
• Have pil­lows and posi­tion­ing aids ready ahead of time to poten­tial­ly ele­vate your hips or legs — be pre­pared to exper­i­ment your first time set­ting it up.
• Keep some thick, minimal-​drip gel lube with­in arm's reach
• Maybe lie down on a tow­el, both for your flu­ids and to wipe your hands

You're wel­come.

My verdict on the Hismith Premium 4.0 sex machine

I wish I had got­ten a Hismith Premium sex machine sooner.

Straight up; it’s a seri­ous upgrade from com­pact thrusters. Velvet Thrusters are still spe­cial for their porta­bil­i­ty — say, for a week­end trip or a tote-​bag-​friendly date night.

However, Hismith Premium mod­els win for balancing:

• Versatility — OMG! Compatibility with my favorite big, juicy, squishy dil­dos! Vivacious stroke length range and pow­er! A flex­i­ble dil­do shaft caress­ing my clit or erot­ic overwhelm!
• Value — Do I need all the frills from my sex machine Bluetooth app or the beefi­est and bulki­est bang­ing from Bad Dragon dil­dos? No, I do not, though you might be into that upgrade.
• Vacation-​ready — Hismith fuck machines come in can­vas car­ry­ing bags, which to me is a big deal for tak­ing the toy from home to hotel room to dungeon.

I’m grate­ful to be bet­ter fucked than any roy­al­ty even just 200 years ago.

Some oth­er sex machines spe­cial­ize in dif­fer­ent things — some are even more pow­er­ful, more pre­cise, more Bluetooth feature-​intensive, more cus­tomiz­able, more fan­cy for dou­ble pen­e­tra­tion or simul­ta­ne­ous part­ner play. (If you need some­thing for huge dil­dos, look into their Max mod­el.)

But for me, the Hismith Premium 4.0 is more than enough to fuck my brains out, deep dick­ing with all my favorite deep cervix-​servicing dil­dos. I get the slid­ing, the strength, the next-​to-​nothing soft sounds, the soul-​snatching sen­sa­tions, the screaming.

And if you’re will­ing to for­go the Premium 4.0’s LEDs, the Premium 3.0 mod­el might be your sen­sa­tion­al sweet spot — it's an even more com­pet­i­tive price for what you get.
