Why Buy an Automatic Masturbation Toy

Guys have gotten on just fine using their hand, and they often wonder why they need a fancy automatic masturbator sleeve.

The only way to explain it is as a comparison of degrees:

By this point in your life you know how you like to get off.

You’ve figured out a good way to grip and squeeze yourself and how fast you like to go.

You probably get off every time you want to without any problems.

Is that all you want though?

Kiiroo doesn’t think so and I’m inclined to agree with them.

The Onyx 2 uses a series of contracting rings to simulate thrusting, squeezing, and the motion of your partner.

It gives you a much more lifelike masturbation experience and is honestly pretty incredible.

You can use this kind of masturbator alone, paired with porn, or with a partner.

The Onyx 2 from Kiiroo

One of the most innovative uses for the Onyx 2 is for couples in a long distance relationship.

It allows them to play together using paired toys no matter where they are in the world.

Overall automatic masturbators are lots of fun, but you do need to ask yourself several things before buying one.

Automatic blowjob machines aren’t cheap, so you do need to consider your budget.

Most cost $200 or more and many require additional accessories to reach their fullest potential.

Another big consideration is how you’ll be using it.

If you travel a lot you probably don’t want to lug around a heavy, battery powered male sex toy you can’t put in your checked bag. A fleshlight would be a better option for this.


Don’t get me wrong, I think they’re great products that provide a lot of value.

I just want you to make sure you’ve thought things through before making a purchase.

Bottom line:

If you have the budget and you plan to use it at home, these are definitely worth it in my opinion.

The Kiiroo Onyx 2: An Overview

Kiiroo Fleshlight Onyx 2

The Onyx 2 is and updated version of Kiiroo’s popular Onyx male masturbator.

Right now this is rated as our top male sex toy of the year!

It uses 10 contracting rings that work in sequence to simulate sex or a blowjob.

The inner sleeve is made by Fleshlight for maximum pleasure and is removable for easy cleaning.

Out of the box it comes with the masturbator itself, a USB charging cable, a sample pack of lube and the insertable sleeve made by Fleshlight.

You also get a manual and warranty registration card, but those aren’t nearly as fun are they?

By itself it’s a pretty great automatic masturbator but that just scratches the surface of what it’s capable of.

The Onyx 2 has full Bluetooth connectivity features.

It can be paired with a wide variety of porn or linked to other sex toys.

You can use this to play with your favorite cam models or spend intimate time with your partner while away from each other.

The Onyx 2 has a 1000 mAh battery that charges up with a micro usb cable.

You get about an hour of play for every 4-6 hours of charging.


  • Relatively lightweight and compact for automatic masturbation toys.
  • New design incorporates a more powerful yet quieter motor.
  • Able to link up with porn, cam girls, or a partner’s toy.


  • Doesn’t provide actual thrusting.
  • Has a much less textured inner sleeve than many competing masturbators.
  • Has long charging period, though comparable to similar products.
  • On the pricey side at $200+.

The Key Features

So the Kiiroo Onyx 2 is a cool Bluetooth connected blowjob simulator, but what does that really mean?

Let’s break down each part of what makes the Onyx 2 so special and why you should seriously consider picking one up.

Powerful Motor Rings

Arguably the most important part of the Onyx 2 is its powerful motor.

It uses 10 contracting rings with a textured feel to them to simulate a milking, thrusting motion.

It has more power than the original Onyx’s motor and yet is somehow still quieter.

When going full blast it’s significantly quieter than something like a fan.

I didn’t find it at all distracting by itself and if you use earbuds or headphones you can’t hear it at all.

What’s really cool though is how powerful it is.

Kiiroo claims it can provide 140 strokes per minute on maximum speed and I don’t doubt that it will.

When going full blast it feels like you’re just pounding away with a partner, the intense stroking and clenching action doing everything it can to get you off.

The speed is just one part of the equation though:

What really sets the Onyx 2 apart is how much you’re able to control the sequence and pacing of the rings.

Solo Play

The solo play function of the Onyx 2 is impressive, though it is overshadowed a bit by the connected features.

To get started you just slip the Fleshlight Superskin sleeve into place and lock it in with the plastic ring.

You should always thoroughly lubricate the Onyx 2 and your penis before play.

Like with most male sex toys I recommend you only use water-based lubricants for this.

Make sure you insert your penis before you turn it on.

There’s a power button located on the front of the Onyx 2 that activates it and starts it running on low.

You can adjust the pace using the touch sensitive pad above the power button.

Just run your finger up and down the length of it to speed it up or slow it down until you find that sweet spot.

If you’ve already connected it to the Kiiroo Feel Connect app you can also control it from there.

This lets you precisely target the pattern and speed of the contractions as you play.

Many people I’ve spoken to in the past mentioned that thrusting in and out of the Onyx 2 was a great way to increase your pleasure.

It combines the automatic contractions with real thrusting, though of course just letting it do all the work feels amazing too.

Online and Paired Options

Here’s where things get really interesting:

The Onyx 2 was designed from the ground up with Bluetooth connectivity in mind.

The Kiiroo Feel Connect app allows you to pair your masturbator with porn, other toys, or simply give you greater control over the motion.

Getting started is easy, just download the app and follow the steps outlined in Kiiroo’s quick setup guide.

Once you’re hooked in you can choose from a variety of traditional or VR porn to play with.

Kiiroo’s specialists have created programs that sync the motion of your Onyx 2 to what’s happening on your screen.

You feel every inch of the porn stars tight, wet vagina as the actor thrusts deeply inside her.

Enjoy playing with cam girls?

There are several camsites that set up their performers to connect with your Kiiroo products.

You can tip your favorite cam girl and let her give you a virtual handjob while controlling the pattern and speed of the vibrator inside her.

In a long distance relationship?

sex toy set for couples from kiiroo

Kiiroo has a special couples pack that includes an Onyx 2 and one of several Bluetooth capable vibrators.

Once they’re linked together you can adjust your partner’s toy while they tease and suck you using yours.

For couples frequently apart for work they’re a great way to have an intimate experience together.

This toy was the top pick in my long distance sex toy buying guide.

Travel Friendly

One of the biggest drawbacks of most automatic male masturbators is how bulky and heavy they are.

The Onyx 2 beats out the majority of the market here.

Just looking at it you can see the work Kiiroo put into keeping it slim and discreet.

It has a slimline black body that looks very nondescript from the outside.

There’s a plastic cap the seals it off when you aren’t using it and the whole thing is just over 10 inches long.

Even including the battery and sleeve it weighs under three pounds.

That’s incredible compact and lightweight compared to its competitors.

Given that it’s marketed to guys in long distance relationships this is a major selling point.

Lots of consultants, managers, and other hard working professionals find themselves away from home a significant amount of the time.

Being able to fit this discreetly into your carry on for some naughty play with your partner is a great way to keep your sex life going when apart.

Customer Reactions

People who use the Onyx 2 consistently praise its sleek and attractive design.

They love how easy it is to set up and get started and how many intense strokes it can provide per minute.

Most loved the library of pairable porn and many remarked on the fun it allowed them to have while they were away from their partner.

A few complaints were made about the long charge time but as everyone with a smartphone can tell you, it takes a while to charge back up a lithium ion battery.

Alternatives: Other Great Automatic Masturbators

Fleshlight Launch Powered by Kiiroo

Fleshlight Launch Powered by Kiiroo

It’s no surprise to find another of Kiiroo’s products compared against the Onyx 2.

They make some of the best and most interactive male sex toys on the market.

The Fleshlight Launch is arguably better than the Onyx 2, but does fall short in some specific categories.

Key features of the Launch include:

  • Let’s you use any Fleshlight product.
  • Includes full Bluetooth connectivity features.
  • Provides actual movement and thrusting.
  • Can be paired with a large library of porn or linked with a partner’s toy.

The Fleshlight Launch is actually a two part system. The Launch itself is a circular device that you slot any Fleshlight into.

Once in place it begins to physically move the Fleshlight up and down on your penis.

Watching it go is actually kind of wild at first.

The sensation it provides with this motion needs to be felt to be understood.

Suffice it to say it’s probably the best pure blowjob simulator experience possible.

The Launch has all the same connectivity features that the Onyx 2 does as well. You can use it with porn, cam girls, or pair it with your partner’s toy.

I hesitate to say that one is better than the other because they’re truly different products.

The Launch is an excellent at home male masturbator. It gives you the most realistic simulation of sex available at the moment.

The problem is it’s not very portable at all. You need to take both the Launch and any Fleshlights you want to use it with.

The Onyx 2 has everything the Launch does except for the physical thrusting.

Carefully consider where and how you’ll use your automatic masturbator and make your decision based on that.

AutoBlow 2

AutoBlow 2 blowjob simulation machine

The AutoBlow 2 is another automatic male masturbator that uses a very similar mechanism to the Onyx 2’s.

It has 5 instead of 10 arms that move up and down your penis within a textured sleeve.

Key features of the Autoblow 2 include:

  • 5 moving beaded gripper arms to tease and stimulate your penis.
  • Uses A/C power for extended play sessions.
  • Built from heavy duty materials to last.
  • Allows the use of several textured sleeves.

The Autoblow 2 is the updated version of the original AutoBlow product.

It provides 50% more gripping strength and power than the original and is overall more robust.

The actual masturbatory experience it provides is top notch and it’s usually a little bit cheaper than the Onyx 2.

Like the Onyx 2 it doesn’t give you a real thrusting sensation but the moving beads do a great job simulating a pulsing vagina.

Where it really falls short is in connectivity features.

As of now it doesn’t allow any kind of pairing with porn or other toys.

If you’re just looking for a stand alone automatic male masturbator it gives the Onyx 2 a good run for its money.

Final Thoughts

When it comes right down to it you have to ask yourself one question:

Do you need an automatic male masturbator?

Probably not… But I bet you want one pretty badly.

They’re one of the best ways to improve your solo play sessions or be intimate with a partner over long distances.

The Kiiroo Onyx 2 is a well made male masturbator that’s absolutely packed full of interesting features.

It combines a really nice physical experience with tons of innovative connectivity options.

You can enhance your private time with porn or give your partner a way to get you off no matter how far away you are.

To me, that definitely warrants some serious consideration.
