Zwei Wanna Rock and Roll All Night

Truly innovative, this is a toy that is versatile and elegant. It can be used by men and women, anally or vaginally and by a variety of experience levels. There is a bit of a learning curve, but the effort is worth it. The payoff is amazing G-spot and P-spot stimulation that will leave you breathless.
Well Made
Doesn't allow for easy use of an additional clitoral vibrator
Rating by reviewer:
extremely useful review


I bought and reviewed the Stronic Eins as soon as it came out, so it was a no-brainer that I needed the Stronic Zwei. It works on the same technology, which is basically a heavy weight which is propelled back and forth by magnetic force, so it mimics natural thrusting. It is the answer to a thrusting toy that doesn't take up a lot of space, and require you to explain to any visitors to your house what that large contraption sitting in the corner is.

While the Stronic Eins was designed for vaginal use only, the second iteration of the Stronic line, the Zwei, was designed for both vaginal and anal use. The large flange area near the handle ensures that it is anal safe. While the hope for some was that the Zwei would offer clitoral stimulation as well, in reality that doesn't happen. The flange does contact your clitoris, but as the Zwei doesn't vibrate at all, it offers little in terms of clitoral action. What it does do, it does well. It thrusts and massages your G-spot of P-spot amazingly well.

The Zwei could be used by men or women, and will certainly have an equal appeal to both. It is waterproof, which is a nice feature in any toy.

Material / Texture

The Zwei is made of silicone and plastic. The insertable portion is silicone, and the handle is made of black plastic. Silicone rates a 10 out of 10 on the Eden Safety Scale. The silicone used on this toy is hypoallergenic, latex free, non-porous, and phthalates free.

The texture on the Stronic Zwei is similar to the textured silicone used for the vibrators in Fun Factory's G4 line. It seems to be a love it or hate it situation. Fun Factory silicone tends to be a little on the rough side, but the silicone used on the Zwei is a bit smoother than the silicone used for the Eins. There is a lot of drag to the surface, but I don't consider this to be a negative, as I generally enjoy the rough texture of Fun Factory toys. In this case, the rough texture means that you get some grabbing while it is thrusting. The silicone seems to grab and hold on to the skin at the vaginal or anal opening and carry it along during the thrust. The only way to combat this is to use a substantial amount of lube. If you are using this anally, you'll already be using lube so it won't matter to you, but if you intend to use this vaginally, know that you will need to supplement with lube to get a comfortable thrusting sensation.

There is no texture aside from the roughness of the surface and the bulges that make up the shaft. The silicone is a thin coat which surrounds a plastic core, so it has very little give or flex. The flange is flexible and bendable, and feels comfortable against your body whether it is used vaginally or anally.

The plastic used on the handle is smooth but matte. Plastic rates an 8 out of 10 on the Eden Safety Scale. The buttons are made of a shinier plastic and are comfortable to press.

There is no smell or taste to any part of the Zwei. There are no visible seams or imperfections in the silicone or plastic.

Design / Shape / Size

The upward hook at the tip does an amazing job of hammering your G- or P- spot, and the diameter makes it a versatile toy. It's large enough to satisfy most users vaginally, and not so large that experienced anal players won't be able to use it. The length seems short at first glance, but is certainly long enough to reach your sweet spot. If you are new to anal play, it will most likely be too large for you, but you can certainly work up to it.

One issue I encountered using this toy vaginally, was the flange that makes it toy anal safe seems to get in the way of any additional clitoral stimulation you'd like to add. I couldn't get a nice point of contact with an additional clitoral vibrator while using the Zwei, it blocks off the good parts. If you need vibration along with the thrusting, you can always hold your vibrator against the Zwei, so it will both vibrate and thrust. Yes, the vibrations will be slightly deadened, but it still does the job.

The handle is comfortable and easy to hold. You need to strike a balance between holding the Zwei so it doesn't get away from you, and not holding it so tightly that you inhibit some of the thrust. Once you find that sweet spot, it will amaze you how much it mimics the real thing.

I wouldn't call it discreet. If you leave this laying around, it is fairly obvious it's a sex toy.

Functions / Performance / Controls

The Stronic Zwei is controlled by three buttons: a plus, a minus and a "fun" button. To turn the Stronic Zwei on, you press the "fun" button. It will begin on the "perfect start" setting. Pressing the "fun" button again turns the toy off. No matter what setting or mode the Stronic Zwei is currently on, pressing the "fun" button will turn it off immediately. To turn the Stronic Zwei off while in this mode, you press the "fun" button again.

There are two distinct modes with the Stronic Zwei: the constant/dynamic mode and the algorithmic mode. Once you press the "fun" button, and are in "perfect start" mode, if you press the "+" button you will enter the constant/dynamic mode. Pressing the "+" again will cycle you through the 6 settings in the constant/dynamic mode. If you wish to move back through the settings within that same mode, you press the "-" button. The six settings in that mode are: Samba, Rumble, Quicky, Rollerball, Vienna Waltz, and Rumba. If, after pressing the "fun" button to turn on the Zwei, and you are in the "perfect start" mode, you press the "-" button instead, you will enter the algorithmic mode. Pressing the "-" again will move you forward through the 3 settings within that mode. Pressing the "+" will move you back through them. The 3 settings within the algorithmic mode are: Rattle, Gallop, and Dirty Dancing. To turn the Stronic Zwei off while in this mode, you press the "fun" button again.

Once you get the hang of the controls, they are easy to use. You have the option of several speeds of steady thrusting, or some thrusting patterns, which is pretty unique. There is one very rapid setting which is more like a flutter, and is the closest feeling to a standard vibration. But, be warned; this isn't a vibrator. The Stronic Zwei is very quiet and certainly wouldn't be heard through a door or by your roommates.

The Zwei uses the Fun Factory Click and Charge technology. The plug-in adapter has a magnetic disc that attaches to the toy. On the handle of the Zwei are two small silver magnetic connectors, and when you hold the charger disc close to that spot, it clicks right on. When it's charging, the wording on the disc glows red. Be aware that it can be a little tricky to get it to stay charging. If the disc gets shifted it may lose its connection, so be sure to put it somewhere it won't be bumped while it's charging. Fun Factory warns you to not leave the Stronic plugged in and charging for more than 16 hours. It takes between 3-4 hours to charge, and I'm getting over an hour of use with each charge. Your use time will vary depending on the settings you choose.

You can lock the Stronic for travel, by holding down the "fun" button and the "-" button at the same time. While it's locked you can be sure it won't accidentally get turned on while it's packed in your luggage. To unlock the Stronic Zwei, you press and hold the "fun" button and the "+" button at the same time.

The Stronic Zwei is waterproof, and can be taken in the tub. I will warn you that although I really enjoy using toys in the tub, I didn't care for using this one while I took a bath. The thrusting action really needed lubrication, and lots of it. I found that all lubes I used rinsed away too quickly in the water and left me with too much drag. That being said, it certainly didn't lose any intensity in the water.

Care and Maintenance

You can use a mild soap and water or a toy cleaner to clean the Zwei. Because it has a motor, you can't boil it to sterilize it, or place this toy in the dishwasher. You should avoid using silicone lubes to avoid a negative reaction with the silicone of the toy. Any water based lube can be used with the Zwei. You may need a quite a bit of lube because of the rougher texture of the silicone. I find that using a liberal amount of lube when you start playing works well, and helps make inserting the toy easier until I make enough of my own natural lubrication. There are no nooks and crannies that hide fluids or make cleaning difficult. I find the Zwei an easy toy to care for.

The Zwei can be stored in the box it came in, which is well designed for storage. If you choose to store it somewhere other than the box it came in, be sure to avoid storing it in contact with other silicone toys. If you store silicone toys touching each other, they will damage each other.


The packaging is pretty standard for Fun Factory. There is an outer sleeve and an inner box. Within the inner box, the Stronic rests in a cardboard area, secured with cardboard spacers. The changer has its own little area to the side. There is a small instruction booklet which details how to operate the controls, how to clean it and how to charge it. As is the norm with Fun Factory toys, most of the information is conveyed through pictures, and no written words.

Although not particularly elegant, the package isn't trashy. There are several small pictures of men and women in an embrace, but they are not prominent in the package design. I use the box for storage, and it stacks easily in a toy box or drawer.
