HiSmith Purple Premium Sex Machine Review: Is It Worth Buying?

HiSmith Purple Premium Sex Machine Review: Is It Worth Buying?

The HiSmith Purple Premium Sex Machine (Remote and App) is worth buying if you want the Premium platform and you want it in purple. HiSmith publishes the same internals for the Purple as for the Gold: a 100-watt mute turbine motor, 0 to 240 RPM, 300 N.cm of torque, a 3 to 15 cm adjustable stroke, 30 to 50 dB, 11.5 kg. The purple is an anodised finish, not a different machine.

Who this guide is for

You have decided a thrusting machine is worth the money, you have narrowed it down to the HiSmith Premium family, and now you are staring at a purple one and a gold one and a plain one and trying to work out what the difference actually is. This guide answers that, using the figures HiSmith publishes and nothing else.

What you actually get in the box

The Purple Premium arrives with a 21 cm (8 in) silicone dildo already included, so you can run it on day one without buying an attachment first. HiSmith lists the box contents as the machine, a power supply, the 21 cm silicone dildo, a wire-speed dial, a remote controller and a portable carry bag.

Here are the specifications HiSmith publishes for this machine.

One correction to a description you will see repeated elsewhere, including in an earlier version of this review: this is not a desktop toy. It is an 11.5 kg machine on a steel frame. HiSmith sells a lift platform and an anti-rotation base plate for it precisely because it is meant to be positioned properly, not perched on a bedside table.

The motor and the noise figure, corrected

HiSmith describes the Purple Premium's motor as a 100-watt mute turbine motor producing 300 N.cm of torque at speeds up to 240 RPM. It is not a DC motor. An earlier version of this review said the Premium line uses a DC motor and that was wrong. The confusion is understandable: the power brick outputs DC 24 V at 4.2 A as a safety voltage, so there is DC in the system. That is the supply, not the motor, and HiSmith does not describe the motor that way.

Noise is published, not mysterious. HiSmith states an operating range of 30 to 50 dB for the Purple Premium: roughly 30 dB at low speed, rising to about 50 dB flat out. An earlier version of this review told you to check the product listing for a decibel figure. The listing had it all along. For context on what that means in a shared house, our guide to quiet sex toys covers how far sound actually travels through a wall.

What HiSmith does not publish for this machine is a continuous-use limit. Some machines in the HiSmith range carry one. The Purple Premium does not have a stated duty cycle, so do not assume it can run forever and do not borrow a limit from a different model.

Purple vs Gold vs the standard Premium

The honest question is not whether the Purple Premium is good. It is whether the colour is worth any difference in price. So here is the comparison, using published figures only.

Purple vs Gold. There is no functional difference in anything HiSmith publishes. Same motor description, same torque, same speed range, same stroke, same noise band, same weight, same mount, same app, same remote range. Both finishes are produced by metal oxidation rather than paint, which is why HiSmith says they will not fade. Choose on looks, because there is nothing else to choose on.

Purple vs the standard Premium (Remote and App). This is where the Purple loses. The published motor figures are identical (100 W, 300 N.cm, 0 to 240 RPM, 3 to 15 cm, 30 to 50 dB, 11.5 kg), but HiSmith lists a 20 m remote range for the standard Premium against 10 m or more for the Purple and the Gold. HiSmith also describes the standard Premium's motor as a high-efficiency brush motor rather than a mute turbine, while quoting the same output figures for both. If the colour is worth nothing to you, the plain Premium is the better buy and you should not pay a cent extra for the anodising.

Purple vs Servok Premium. The Servok is a different machine, not a spec bump. It uses a servo drive instead of a crank-link mechanism, its stroke runs from 1.7 cm to 17 cm, and crucially it changes stroke depth from the app while running. On the Purple you stop the machine and reset the locking screw knob. If you want to start shallow and go deeper without pausing, that difference matters more than any colour. What you cannot say is that the Servok is quieter, because HiSmith does not publish a noise figure for it. An earlier version of this review claimed servo motors are quieter. That claim was not supported and it is gone.

Purple vs Premium Original. The Original has no remote and no app. If hands-free or partner control is the reason you are buying a machine at all, the Original is not the one.

Attachments and their real dimensions

Every attachment on this machine mounts through KlicLok. KlicLok is HiSmith's own patented eight-sided click connector, built into the machine. It is not a separate brand, not a company and not a rival to HiSmith. There is no third-party KlicLok ecosystem to shop around in: non-KlicLok toys attach only through a HiSmith adaptor. The eight-sided geometry is what stops the attachment spinning while the machine thrusts.

The machine already comes with a 21 cm silicone dildo, so treat everything below as an addition rather than a necessity. Here are the figures HiSmith publishes for the popular purple-family attachments. Read the diameters before you read the names.

Two things worth saying plainly. First, the 6.7 in vibrating purple dildo is often called a beginner attachment. At 3.5 cm across it is not tiny, and HiSmith positions it for anal and prostate use rather than as a starter size. Second, HiSmith's specification list for the 8 in pink and purple dildo does not mention vibration at all, despite the word appearing in the product name, and the diameter HiSmith lists for it is 9.9 cm. Do not buy it expecting a mid-size vibrating toy. An earlier version of this review described it as a modest step up with vibration built in. That was wrong on both counts.

All of these are 100 percent silicone. Water-based lubricant only: silicone lubricant degrades silicone. HiSmith also warns that storing silicone in contact with PVC toys causes a chemical reaction that damages both.

Setup, stands and the suction cup adaptor

The Purple Premium adjusts for both height and angle out of the box, and HiSmith sells two accessories that change what you can do with it. The Premium Lift Platform is a pneumatic stand with a 55 to 80 cm height range, a 50 x 32 cm ABS top and a carbon steel frame rated to a 60 kg static load, on four lockable castors. The Anti-Rotation Non-Slip Base Plate is a 50.5 x 34 x 6.5 cm plate that sits under the machine and stops the stand rotating, with a non-woven top surface so it can be used on a bed.

The KlicLok Suction Cup Adaptor is the accessory most often misunderstood. It does one job: it lets a suction-cup dildo with a base of 11.3 cm or under clip onto the machine's KlicLok mount. It does not stick the machine to a wall, a floor or a bed frame. It is not a load-bearing anchor and it will not hold your weight or the machine's. If a dildo's base is wider than 11.3 cm, HiSmith says it is not suitable for this adaptor, and that is a limit, not a suggestion.

Safety: stroke depth, anal use, cleaning

A 100 W motor on a rigid rod does not get tired and does not feel you flinch. That is the whole point of the machine and it is also the risk. Set the limits with the hardware before you start, not with willpower once it is running.

• Set stroke before you start. Never during. The Purple Premium's stroke runs from 3 cm to 15 cm and is set with a locking screw knob. HiSmith's own attachment instructions say not to adjust thrust depth while the machine is operating, and to make sure the depth knob is locked before switching on.
• For anal use, start at the shortest stroke. That is 3 cm on this machine. The maximum is 15 cm, and it is worth knowing the real number rather than a comforting one, because 15 cm of driven thrust is a serious depth.
• The rectum does not self-lubricate. Lube is not optional and you will need more than you think. Reapply. Water-based only, because every silicone attachment here is degraded by silicone lube.
• No numbing or desensitising products. Pain is the signal that tells you the machine has gone too far. A machine will not notice you have switched that signal off.
• Stop on sharp pain. Bleeding means stop and seek medical care. Do not push through it.
• Never go anal to vaginal without washing the attachment thoroughly or changing the condom on it.
• Flared base still matters off the machine. Attachments like the 7.5 in slim anal dildo have a removable KlicLok plug. On the machine, the mount holds it. Off the machine, anything used anally must have a flared base, or it can be drawn into the rectum and require surgical removal.
• Keep hair, fingers and bedding clear of the drive rod while the machine is running.
• The suction cup adaptor is not a mount. It accepts suction-cup bases of 11.3 cm or under. It does not anchor the machine to anything.
• No published duty cycle means do not invent one. HiSmith does not state a continuous-use limit for the Purple Premium. If the motor housing gets hot, stop and let it cool.
• Not rated waterproof. HiSmith does not publish a waterproof or IP rating for this machine, and it runs off mains power. Keep it dry. Never submerge it.
• Cleaning. Wipe the machine down; do not put it near water. Silicone attachments can be washed with toy cleaner and warm water. Never boil, dishwasher or bleach anything with a motor, battery or charging port, which rules out the 6.7 in vibrating attachment. Air dry fully, and store silicone away from PVC.
