Excited For A Thrashing Whale Tail

When I first heard about the Fun Factory Bi Stronic Fusion I loved the idea of this super flexible “whale tail” design providing some broad stimulation to the clitoris. From the look of it, this was a great design idea for some delicious clitoral stimulation – a thick, rounded base in the middle for some pinpoint stimulation and the flexible “wings” on either side to spread out the vibrations. What’s not to like? Of course, the thrusting feature also fascinated me. My eyes lit up with excitement when I first turned it on and it felt like the vibrator was trying to escape my grip! I’ve never tried a thrusting or pulsating toy before, so it’s safe to say I was excited to see what was in store. At first glance, this thrusting dildo vibrator definitely seemed like it would deliver some serious pleasure, and I was down for the ride!  

The Issue With Rabbit Vibrators

As much I wanted to love the Fun Factory Bi Stronic Fusion, I have to admit that I never got it to work for me. No matter how much I tried to use it in different ways and in different positions and angles, this vibrator just couldn’t provide me with enough stimulation to bring me to orgasm (or even remotely close!). I’ve never really had much luck with rabbit vibrators as I often feel like my anatomy just doesn’t align with the fixed distance between the shaft and the clitoral stimulator. Either I don’t get the right kind of pressure on my clit or the shaft is pressed into an awkward angle. This was also the case for the Fun Factory Bi Stronic Fusion.  

Idea VS Execution

As I mentioned earlier, I really did have high hopes for this sex toy. I still do think that the ideas behind the overall design of this product are great! Although, the execution just leaves some things to be desired. That silicone “whale tail” can provide some broad clitoral vibrations, but the “flexibility” is still compromised by the angle of the internal shaft, as the tail will then dig into your clit when maneuvered into a different position. When this happened, I couldn’t enjoy the vibrations as they were not quite hitting the right spots for me. However, the insertable shaft has a good size and shape to it and I really enjoyed the hands-free thrusting! I actually found myself wanting to enjoy the thrusting without having the “whale tail” in the way. In order to orgasm, manual clitoral stimulation usually works for me, and I like to have the option of slightly moving around whichever object I’m using to stimulate my clit (whether that’s a vibrator or a clit sucker). With the Fun Factory Bi Stronic Fusion, the little pleasure I could enjoy from the pulsating motion would never be able to assist me towards an orgasm as the clitoral tail gets in the way for any manual massage. So, while there are pleasurable intentions behind the design, the (non-adjustable) execution makes this toy quite difficult to use if one’s anatomy does not line up perfectly with the features of the product.

The design represents both the good and the bad about my experience with this toy. I still believe this is a beautiful rabbit vibrator that (ideally) provides stimulation to all the right spots. The smooth and girthy shaft with a few ridges along the side features a slightly curved tip for extra g-spot massage. The "whale tail" has a thick and rounded center for firmer direct clitoral stimulation and thinner flexible "wings" to envelop the clitoris and send the vibrations to a broader area. As impressed as I am by the overal design of this product, I also have to emphasize how it is exactly the design that made it impossible for me to use. The fixed distance and angle between the two stimulation points simply did not work for my body - and that's probably the case with a lot of other people with similar anatomies. I feel there are ways Fun Factory could have made the Bi Stronic Fusion a little more adjustable and accessible to a more diverse group of people.

Obviously, I found the Fun Factory Bi Stronic Fusion quite diffult to use in order to build pleasure, but that was more of a design issue. If you find that this product works really well for your body then I will say that the Fun Factory Bi Stronic Fusion is very easy to use. The three-button conrol panel allows you to easily adjust the different stimulation modes without having to scroll through each one every time. The "FUN" button activates the motors when pressed for half a second and also works as an immediate off-switch. The buttons are also well-placed on the handle so you can easily access them during use.

I already own my fair share of products from Fun Factory. I am familiar with the overall quality of products from this brand. Despite my critique, I will emphasize that I think the Fun Factory Bi Stronic Fusion is a premium quality product. It delivers impressive pulsations and vibrations that are powered by two separate motors. It is USB rechargeable with a magnetic charging cable. It's also 100% submersible for bath-time play. All in all, whether it works for me or not, this is a great quality product.

The Fun Factory Bi Stronic Fusion is definitely not a cheap toy. Of course, I personally think it's a bit too expensive for something that only works for certain body types or anatomies. It would definitely be disappointing to cash out on something that basically doesn't get the job done for you. That said, it is a toy that delivers a lot of different sensations, is completely waterproof, anal safe, and generally great quality. Sure, it's not going to be cheap! If your anatomy is compatible, I'm sure it's actually a great investment in your pleasure. But I think it potentially is a lot of money to spend on something that you can't be quite sure will work for you.

The Fun Factory Bi Stronic Fusion performs well in the way that it definitely packs some power in those stimulation modes. I am still very impressed and pleased with the different thrusting modes - again, I would have loved if I cold enjoy this feature by itself! I also tried using the vibrations in the "whale tail" independently, while the shaft was not inserted. The powerful vibrations there felt quite enjoyable on my nipples, labia, and clitoris. The Fun Factory Bi Stronic Fusion stays true to its promises of intense stimulation modes and that is a big plus!

The Fun Factory Bi Stronic Fusion comes in a sleek box that slides right open. The top layer of cardboard holds all the informational pamphlets. There's a user manual with all the information you need to operate the toy, along with some tips and tricks of fun ways to use the Fun Factory Bi Stronic Fusion. There's also a small safety pamphlet with warnings for safe use of the product, as well as a general warning attached to the handle of the toy, saying that use of this product may be harmful for pacemaker wearers. Included is also a long magnetic USB charger.

The Fun Factory Bi Stronic Fusion is made of 100% body-safe and non-porous materials: silicone and ABS plastic. It is fully waterproof and super easy to clean before and after use. Simply rinse off any residue, lather it up with a mild, unscented soap (or your favorite sex toy cleaner), and rinse throughly with warm water. Let it dry completely before storing it safely away from lint and dust. A lot of Fun Factory products have this slightly sanded silicone that feels a bit grippy. It very easily collects dust and hair, so be sure to clean it before use as well!

As mentioned earlier, this is not my first rodeo with rabbit-style vibrators. While I’ve come to terms with the fact that some of them just don’t work for me, I still appreciate the features individually. A special feature of the Fun Factory Bi Stronic Fusion is the strong pulsating motion that is meant to provide some hands-free thrusting bliss. The thrusting sensation is very impressive, and definitely something I would love to explore indenpendently of the clitoral vibrations! The “whale tail” is also an impressive component, as I initially thought the design would do wonders for my clit. Who knows, maybe it would have with the right placement.

  • Powerful thrusting motion
  • Anal safe
  • Broad wings for enveloped clitoral stimulation
  • 100% waterproof

  • Long charging time VS battery life
  • Not suitable for people with a pacemaker
  • May not work for everyone's anatomy

Don't get me wrong. I don't dislike the Fun Factory Bi Stronic Fusion. I really do think it is a premium quality sex toy. I really hoped it had sent me to pleasure (and orgasm) heaven, but it was simply not a match for my vulva. If it is a match for you, I'm pretty sure this toy could quickly become a staple in the bedside drawer. Although, I don't want my personal experience to inform my overall rating too much, I still feel like my underwhelming experience is not unique. If this toy really does not work with my anatomical dimensions (in terms of flexibility and stimulation angles) then the overall design is partly flawed, as many others may also experience that this design simply does not align well with their erogenous zones. I do think there are few improvements to be made in terms of making the toy more adjustable (not just flexible) as this might render it much more accessible to a wider range of people.

Although I’ve tried my best to give you all the information you need about this vibrator, I might have missed something. If you still have some unanswered questions about how this toy works, take a look at the full user manual for the Fun Factory Bi Stronic Fusion here!

Since the Fun Factory Bi Stronic Fusion is made of silicone, it is not advised to use any silicone or oil based lubes. These will damage the material over time. You should always opt for good quality water based lube when using the Fun Factory Bi Stronic Fusion.

Anyone who wants to! Even though the Fun Factory Bi Stronic Fusion is designed to give optimal amounts of pleasure to vulva and vagina owners, that doesn't mean that other people can't use it. First of all, people who are partners to vulva and vagina owners can obviously share in the pleasure by using it on their partner. Secondly, the Fun Factory Bi Stronic Fusion is also safe and suitable for anal play! That means anyone with an anus can enjoy it. For non-vagina owners, the "whale tail" can even stimulate the perineum while the curved shaft massages the prostate.

You can always use any sex toy with a partner, by asking them to use it on you, use it on them, or have them watch you use it on yourself. Those are the basics. But a great bonus about the Fun Factory Bi Stronic Fusion is that you can also use it for some intense double penetration. The handle may be a bit bulky to maneuvre around but it is not impossible to engage in some triple stimulation with clitoral vibrations, pulsating g-spot vibration, and some anal penetration with a penis or dildo.
