If you have used a regular TPE dildo before, the first thing you are likely to notice when looking at the Hismith Auxfun Extra Length is not its shape, but the Flexible Pipe at the back.
That was also the main question I wanted to answer after actually testing it:
Is this flexible pipe just an interesting-looking design, or does it actually make a difference during use?
For this test, I did not look at it simply as another TPE dildo. Instead, I focused on its flexibility, the changes brought by the extra length, the connection structure, and whether it remained comfortable during longer sessions.
My conclusion is fairly straightforward: the Flexible Pipe is not a meaningless design, but the difference it makes is not quite as dramatic as the product photos might suggest.
If you are looking for an adult toy that is longer, softer, and can also be used with the Hismith system, there are several things about this product worth considering.
Designed for users who want deeper reach, stronger fullness, and a more customizable machine-assisted experience.

Hismith Auxfun Extra Length TPE Dildo: What Did I Actually Test?
This is a product that is clearly positioned as an extra length dildo.
It uses TPE material, and its overall feel is different from that of a typical silicone dildo. TPE usually feels softer and more elastic, but that also means you need to pay more attention to cleaning and storage.
If you are comparing TPE with other common dildo materials, Glass vs Silicone Dildos: Which Material Is Better? offers a closer look at how different materials affect feel, cleaning, durability, and everyday use.
During my test, I mainly focused on several questions:
- Does the TPE material feel natural?
- Does the Extra Length design actually make a difference?
- Is the Flexible Pipe genuinely useful?
- Is the connection stable?
- Does the increased length make it harder to control?
- Does it feel bulky during longer sessions?
- Is it better suited to regular users, or to people who already have Hismith equipment?
These questions are more useful than simply looking at the product dimensions.
First Impression: Soft, but Not Without Support
The first thing I noticed after handling the product was the softness of the TPE.
If you have mainly used silicone dildos before, the difference between the two materials is fairly easy to notice.
For another hands-on example of how material, firmness, and long-term comfort can affect the experience, you can also read our Tantus Realistic Dildo Review: Realistic Design, Material Performance, and Long-Term Use Experience Analysis.
Silicone usually feels firmer and has a more defined structure, while TPE feels softer and has a certain amount of elasticity.
That is also why TPE dildos are often compared with realistic dildos.
However, there is one thing worth noting here:
Softer does not necessarily mean better.
For an extra length dildo, if the entire product is extremely soft, the increased length can actually make it harder to control.
The Auxfun Extra Length strikes a relatively good balance. The front section has a certain softness, but the overall product does not feel completely unsupported.
For me, that is actually quite important.
The Flexible Pipe Is the Part of This Product Worth Talking About
If this product were simply a TPE dildo with a larger size, there would not be much to discuss.
What really makes it different from a regular dildo is the Flexible Pipe at the back.
Instead of simply attaching a fixed connector to the product, it adds a flexible section that can move.
During use, the most noticeable effect of this design is not that it “adds stimulation,” but that it reduces the very direct and fixed feeling between the product and the connected device.
With a regular rigid connection, the structure can make the overall movement direction feel relatively fixed in certain situations.
The Flexible Pipe allows the product to have a certain amount of natural movement.
The difference is actually quite subtle.
If this is your first experience with a Hismith product, I do not think you will immediately feel that it is “completely different.”
But if you have already used products with fixed connection structures, the difference becomes easier to notice when switching to this type of flexible connection.
Made from soft TPE material for a comfortable yet firm feel, combining flexibility with lifelike texture.
Does the Extra Length Actually Make It Better?
This is where I think the product can easily be misunderstood.
Extra Length is not something everyone needs.
The increased length does change the overall size and feel of the product, but that does not mean the experience automatically becomes better.
If you are unsure how length, girth, firmness, and overall design should affect your choice, Dildo Buying Guide: How to Choose the Right Dildo for Your Body explains the main factors to consider before choosing a dildo.
For someone buying a dildo for the first time, I would actually not prioritize an extra length design.
The reason is simple:
The longer the product, the more control and space you generally need to use it comfortably.
If your goal is simply to find a dildo for regular use, a standard size may already be enough.
But if you already enjoy longer dildos or have used related Hismith equipment before, the positioning of the Auxfun Extra Length becomes much clearer.
It feels more like a product designed for people who already know what they want.
TPE Material: Comfortable, but More Maintenance Than Silicone
This is something I think you should consider before buying.
The advantages of TPE are quite obvious:
It is soft, elastic, and has a noticeably different feel from harder materials.
But TPE also requires more attention when it comes to maintenance than many silicone sex toys.
After use, it should be cleaned promptly and allowed to dry thoroughly. When storing it, you should also avoid leaving it in a damp environment for long periods.
If you are the type of person who puts an adult toy away immediately after use and rarely spends time cleaning or maintaining it, a TPE dildo may not be the most convenient choice.
But if you are willing to take proper care of your adult toys, the soft feel of TPE is definitely one of its biggest advantages.
Connection Stability: Does the Flexible Pipe Make It Wobbly?
This was one of the things I paid close attention to when testing the product.
Because the biggest advantage of a flexible structure is also the thing I was most concerned about:
Once it starts moving, does it become unstable?
After testing it, I think the issue is less serious than I expected.
The Flexible Pipe is certainly more flexible than a completely fixed connection structure, but it does not feel loose or poorly supported.
Once connected to compatible Hismith equipment, the overall setup still maintains good stability.
If you are also considering the machine itself rather than just the attachment, our Hismith Sex Machine Review: My Honest Thoughts After Several Weeks of Use looks at the machine from a longer-term hands-on perspective.
Of course, if you prefer a very direct and highly mechanical movement response, this flexible structure may not be your preferred type.
It places more emphasis on a certain amount of movement and flexibility.
What Type of User Is It Best Suited For?
After this experience, I think the user profile for the Auxfun Extra Length TPE Dildo is actually quite clear.
It may be a good fit for:
- Users who already have Hismith products
- People who prefer TPE material
- Users who want to try an extra length dildo
- People interested in flexible dildo designs
- Users who want to expand the way they use an existing sex machine
- People who already know they prefer longer products
It may not be the best fit for:
- First-time adult toy buyers
- People who prefer a firmer structure
- Users who do not want to spend extra time maintaining TPE products
- People who only need a standard-size dildo
- Users who do not have compatible equipment and do not plan to use the product with a related system
So I would not describe it as a dildo that is “suitable for everyone.”
It actually has a fairly specific use case.
Pros & Cons
Pros
- Soft and elastic TPE material
- The Flexible Pipe does provide a different feel from a fixed connection structure
- Extra Length has practical value for certain users
- Good expandability when used with a compatible Hismith system
- Clear product positioning
Cons
- TPE requires more care when cleaning and storing
- Extra Length is not suitable for everyone
- The product offers fewer advantages if you do not have compatible equipment
- The flexible structure will not appeal to everyone
- Compared with a regular dildo, it is more focused on specific use cases
Final Thoughts: Is the Flexible Pipe Worth It?
Going back to the question I raised at the beginning:
Does the Flexible Pipe actually make a difference?
My answer is: yes, but it is the kind of difference you notice through use rather than something that feels like an obvious upgrade just from looking at the product photos.
If you simply need a regular TPE dildo, there is no real reason to buy this product solely because of the Flexible Pipe.
But if you already use Hismith equipment and want to try a combination of extra length dildo + flexible connection, it becomes much more interesting.
The real selling point of this product is not simply that it is “longer.”
Pronounced veins and raised ring patterns along the shaft provide extra friction and intense internal sensations.
In my view, the more important difference comes from the combination of:
TPE softness + Extra Length + Flexible Pipe + Hismith-compatible connection structure.
Together, these features give it a fairly distinct position compared with a regular dildo.
Overall Rating: ★★★★☆ 4.2/5
ToyBench Verdict:
If you already know that you prefer TPE, a longer size, and have compatible Hismith equipment, this product is worth considering. For someone buying an adult toy for the first time, there is no need to choose it simply because of its specialized structure.
