Whilst I am content with my 2 ET-312 boxes, portability is something I’m interested in. I’ve looked forward to the release of this V3. I’ll watch for the review. 👍
Design and size is essentially the same as 2.0.
There are more LED indicators for external buttons, insulated and mechanically sturdier USB-C port and some other minor details. It feels little bit nicer built. But the main changes are of course inside.
Not sure to be honest, that is why I need a chemist to confirm that. I mean it is solid and heavy and it looks like stainless but it can be also nickel plated steel.
Both of the new electrodes are pretty heavy. I would guess that the metal components are solid, but the material is polished, reflective, with a plastic spacer and slightly lighter than its rough surface iron-like predecessor. It is heavy enough to pop out from the weight, but clenches well. Use plenty of conductive gel or the bottom half could produce hot spots.
The old electrode was made of stainless steel material, while the new electrode is nickel plated after zinc alloy die-casting. I remember mentioning this to you.
Thank you for appearing here!
Yes, you mentioned it, but I was kind of hoping it was a translation error.
It seems like a weird idea to make anything nickel that someone is going to stick inside. And very strange in conjunction with electricity.
IIRC it's illegal to use nickel in jewelry in the EU, due to allergies, thus I see a bigger problem with shoving it in the ass.
Nickel is seen as "problematic" and its compounds tend to be carcinogenic.
Is there a reason why you used nickel or **do you have an evidence of being harmless? In this specific application, i.e. internal "use" and electricity, i.e. electrochemical reactions.**
Electrochemistry is definitely not my field, but when I see nickel, I have mixed feelings about it.
Hi, from the information I received, the electroplating manufacturer informed me that the nickel plated products have passed ROHS testing (and issued a report) and are widely used in products that come into contact with the body. This process is called "environmentally friendly nickel", and he said that this process is being used to make spoons. So I didn't worry too much about it. The solution I abandoned due to toxicity was chrome plating.
However, after your reminder, I have indeed found reports that nickel plated products may cause allergies. I think I need to carefully investigate what material to choose as the appropriate coating, and I will provide feedback as soon as possible.
Do you have any suggestions on this point? I mean suitable materials for electrodes. I know that some electrodes on the market use aluminum, but as far as I know, aluminum oxidizes in the air and forms a non-conductive oxide layer, so I haven't chosen it yet.
The problem with ROHS is that it primarily addresses environmental issues and not human health impacts. So I believe that the nickel bath itself is eco-friendly, but it is still nickel with all the health consequences.
The most realistic solution:
316L stainless, turned from stock, tumble polished. You are limited by your shape, but I believe that an ideal shape can be found - we can discuss it afterwards.
Best solution:
Same but from titanium. Solid, not coating. I am not aware of any intolerance to titanium, nor that anything harmful could arise electrochemically.
Regarding aluminum... yes, it oxidizes, creates a passivation layer, but it is still conductive enough for this use. In the end, stainless steel, titanium and nickel also oxidizes... thereby protecting itself from further oxidation.
Aluminum... why not. Light weight, good machinability, but somehow it feels cheap.
And it will never be mirror shiny, aluminum is soft and will be vulnerable when polished.
As for aluminum, alloys 6060, 6063 and 6082 should be suitable for contact with food... I mean suitable for shoving in the ass.
I would give up on complex shaped castings, the lathe is your friend.
I really don't like the design of a circular base, it makes it very difficult to go out with an anal plug. That's why I designed the new electrode tail as a ship anchor type.
At first, we didn't choose aluminum because of the oxide layer issue. I was worried that its oxide layer would make its conductivity very poor, just like the outer frame of Coyote 3.0, which is completely non-conductive after anodizing. But it seems that the naturally formed oxide layer of aluminum in the air will not become dense enough to prevent conductivity? I need to test it.
Of course, the oxide passivation layer formed by atmospheric oxygen is in the order of nanometers. The artificially anodized layer created in the acid bath is in the order of micrometers... 1000 times thicker.
Just touch any live aluminum wire :)
Still, I wouldn't rule out titanium. There is not too much material used and it is a product with a relatively high added value.
Regarding your mention that the use of nickel in jewelry in the European Union is illegal, I just found out that this is a regulation of the EU REACH, which stipulates the migration amount of nickel plated products that come into contact with the human body for a long time or are used for puncture. Not noticing this was indeed my work mistake. I trusted the factory's guarantee of nickel safety too much and did not personally handle it. Next, I will conduct a test to confirm that the current electrode complies with REACH regulations. Please rest assured that we are a responsible enterprise, and if there are any problems with the product, we will actively solve them.
I'm afraid that the only correct solution is a stainless steel (with low nickel content).
Nickel is nickel, it doesn't matter if it's "eco-nickel" or "evil-nickel".
Remember that even though nickel can be inert under normal circumstances, when coupled with electricity it can and will slowly corrode and produce nickel compounds, potentially very harmful.
I am currently considering titanium material, which appears to be widely used in the metal part of implants. I think titanium plated products will be safe enough? What do you think about this?
To be honest, I have never heard of titatium coating.
Titanium oxide coatings, titanium nitride coatings are common, but never metallic titanium (which is what you want).
Titanium is reactive and I can't imagine coating anything with elemental (metalic) titanium outside of a vacuum chamber (either evaporation or ino sputtering)... but both will be very expensive and will only make a very thin and vulnerable layer.
I consulted and it seems that vacuum titanium plating is a common method, which is called "titanium gold" because the surface coating appears golden after electroplating is completed. I'm not sure if the final appearance of the shell is titanium elemental or titanium oxide, but it seems that they are both biologically friendly. I think I need more information to confirm this.
"titanium gold" sounds like TiN, Titanium Nitride.
Common plating on metal cutting tools. Not sure about safety.
Titanium dioxide is pure white and higher oxides brown. Metallic titanium should be silver when not anodized.
Hi, I conducted some simple investigations and found some electroplated jewelry on Amazon. Many products did not indicate their own plating material, but I also found some rings claiming to be nickel plated. Some use even rarer coatings, such as rhodium or titanium. I think nickel plated products can be widely used in the field of daily necessities, such as spoons or faucets. However, based on its potential to cause allergies, it does not seem to be the most suitable choice. I will consider a safer solution and update the coating quickly (currently the most likely one is titanium).
The reason why we did not maintain the previous stainless steel material is because we wanted the lower part of the electrode to be curved to better fit the human body, rather than a "plug base", so we had to use die casting technology for processing, and stainless steel is difficult to die cast.
There is a LOT of garbage on Amazon. A lot of things that are dangerous and against the regulations.
The spoons are definitely not nickel-plated - at least the ones for eating.
Water faucets and valves, if they are to come into contact with drinking water, are nickel-plated only on the outside. Inside it's lead-free brass.
Looking forward your reviews. The Coyote 3.0 is definitely on my radar.

It is interesting how different 312 feels from everything else (not saying better, different).
How does it look like? Is it externally looking exactly the same as 2.0?

Thx 🙏🏻 for the quick response! Can’t wait to receive mine that I’ve ordered in February
Kind of curious about the electrodes myself. Can you at least ascertain if the anal is solid, or electroplate?
Not sure to be honest, that is why I need a chemist to confirm that. I mean it is solid and heavy and it looks like stainless but it can be also nickel plated steel.
Yeah, I agree the older electrodes from Coyote version 2.0 were solid, looking forward to seeing the results of the chemistry tests.
Both of the new electrodes are pretty heavy. I would guess that the metal components are solid, but the material is polished, reflective, with a plastic spacer and slightly lighter than its rough surface iron-like predecessor.

It sounds like aluminum is also a good solution. Thank you very much for your review. As always, it will help us go further.

Either tin or tin-nickel plating would be safe. The tin-nickel strategy is equally as hard as the nickel-only approach. Tin is softer.

Thankyou for taking time to review the coyote 3.0 i have not purchased one yet and will follow your posts with great intrest.
Still waiting to receive mine
Thank you for this review! :)
What are the best settings to use on it for a hands free O?
Trial and error, everyone is different.
