That's its operating temperature in an industrial application though- I interpret that as the material maintaining it's functional integrity within that temperature range. It doesn't necessarily mean that it's totally stable or not potentially damaging to health when inhaled within that temperature range.

And looking at their data sheet those are just 'typical' properties- they aren't confident enough to offer that as 'specifications'. It also seems to only have a 3 year 'shelf life'? That suggests some degradation over time. How does that work once it's installed?

That said, I think the inhalator uses polyimide stems and it's not at the top of my list of suspicious materials.

Well well said WaTyler. I wish I could have found some more information. I tend to agree with you that it is not to high on my list of suspicious materials. Although it never hurts to do some research.

Even if it is Polyimide tape the operating temperature is: -100° to 500°F (-73° to 260°C) This vaporizer gets to 450F which is 50 degrees under the max operating temperature.

50º is a lot to play with and i am sure those temperatures are given with a margin.. the true maximum and minimum temperature should be higher still. I am not saying there isn't reason to further investigate though, but i don't think the rubber smell is due to polyimide and it seems that there are less inert materials than polyimide inside the DV.

Taken from wikipedia: "Polyimides are also inherently resistant to flame combustion.." .. which leads me to conclude they will sustain the heat without of gassing.

I would still love KarmaClassic to tell us more about this so i can be 100% sure but right now this is not very upsetting.

From post #95, Davinci_vaporizers said "the straw is made from high temp food grade silicone, the airpath and internal components, not counting the circuit board are all high temp food grade plastic (non-gassing) and the soder is non-lead based.

the other components, there are a few last minute changes on some of them. Mostly due to some heating tests we conducted. Going with stronger mil spec plastics in some areas. "

And from post #106, "The vapor path is all high temp food grade silicon, with some plastic flexible wrapping on the outside.

We're currently undergoing a safety certification process for all of our components, though we're not sure if that will come through in time to add it on the first batch of vaporizers out of the factory. Since some components will come in contact with the matter to be vaporizered, we want to proivde as many assurances as possible with actual certification to back up claims.

The heating element is copper

The internal components are mil spec food grade plastics (so no outgassing and no overheating issues) and stainless steel alloys, although some of that may be subject to slight alterations before the actual units are shipped.. A very early prototype had some issues with the plastic getting too warm for our liking, so we upgraded"

So, if we are taking their word for the truth, there should be no problem with the materials used.


EDIT: Just went further down and found this, from Davinci_Vaporizers:

"The chamber is made of an aluminum/steel alloy

There is no circuitry in the airpath. It's just the way they are built, we wouldn't someone taking the unit apart (unless they wanted to void their warranty)"

WatTyler I agree completely, and further more, there are many different types of the tape for different applications. There are some that are safe for medical application. The adhesive used on the tape may be a big part of this as there are many different manufacturers of the stuff so the consistency of materials and quality is an issue.

Venti, is there a way to strip the insulation off the wires and us only the "food grade silicone" as insulation, in the chamber and at least close to the chamber outside? I am also curious about the "food grade silicone" black top to the chamber, it gets very hot as well and it may be heating the exterior plastic, mainly the rubbery paint I suspect. It would be very informative to see the chamber operate outside the enclosure, in a dark room with a bright led flashlight to see where the vapor is coming from.

Vorrange, have you tried cleaning out your unit and running it empty in the dark? Temp up to 430F for a few minutes, get an LED flashlight, shine it at an angle and you will see the vapor rising at a constant rate. You can see this from the side vents also.
I haven't seen the safety certification mentioned by the manufacturer after that post.

Manufacturer: We need to know the materials used, quality of source, etc. What is the composition of the rubbery paint used, the type of plastic used for the shell, and Please understand the need to inform you customer what they are breathing.

First, we recognize this is likely the attempts of our competition who is not happy over the success of the DaVinci and we don't take slander lightly. DaVinci took great care to provide a safe air tract. The wire insulation is high tempo food grade silicon rated to 482 F/250C as are the seals and mouth straw.

In the event your unit is unsatisfactory, please return for a full replacement. DaVinci can also boast that our defect rate on our first production run is less than 1%, which greatly trumps the industry standard in electronic devices.

Question? From what I can tell with my dental mirror the screen in the bottom of the heating chamber looks like it has been tack welded to the chamber in about five places. I have read some people that think this screen can be removed and changed? Does anyone know what is correct regarding this screen? Thanks

I would like clarification with this was well. I don't want to pass along any improper device. Any word from the manufacturer on if the bottom most screen is meant to be removed?

DaVinci, with all due respect it seems you are a bit too dismissive in your response. Although the user who posted the photos of the open vaporizer is not a very old member of the forum it seems impulsive to say the least to accuse him of slander.

The concerns he raised are valid in my point of view, as for many FC users, whether they have a DaVinci or they are looking to have one. In fact, i just read a post of a user going to another thread saying they were looking at the DaVinci and now they are not. This kind of bad press and doubts hanging around is precisely what you don't need.

In the post i made i made reference to something you wrote about not having wires in the air path which we now know it is not true..

So, i ask you that, after about 40 posts about these concerns and others written here in the thread about the vaporizer you are promoting, you give us some of your time to properly adress and answer the doubts and questions we have.

On a final note, i am very happy with your product and i do think there is no great concern here. In my point of view, the only downside for the materials used at this moment is that it affects flavour. I still would like you to treat us better. :)

The opened unit clearly shows the high temp insulation over the plastic coated wires. What do you think is happening to that plastic once the high temp insulation heats up and the temperature of that plastic gets up to about 250 degrees F?

I was also curious why the DaVinci smells like a burning tire:
I've used 2 different units and the only bad smell or taste I've experienced is at the end of the bowl, and that's ABV taste. But since more than half of your posts here on the forum are claiming toxic materials for various models, not surprising.

We still have a rule here about discussion of materials in a vape thread. Let's quit the speculation and comments about smelling something burning that's nobody's previously reported, and let DaVinci supply some info. Meanwhile anyone insisting on getting on a soapbox may just find their post subtracted and an infraction added.

I'm sorry if I sounded dismissive. We have intelligence that suggests a rival is working on a misinformation campaign.

Those aren't plastic coated wires. That is all food grade silicon, as confirmed by our factory engineer.

As you can tell in this thread, a few have had an issue with smell and a lot have not. If you are a davinci owner and have any issues with smell, smoke coming from the unit, etc. call or email us and we will replace it ASAP. We're very dedicated to quality products, but with anything electronic, there will always be a few that have issues.

Vorrange, we are very proud of the fact that we have so many loyal customers in such a short amount of time and we work diligently to earn that loyalty. That includes being fast and courteous if someone has an issue and wants/needs to return their DaVinci.

It's never fun to read about someone having a bad experience with our vaporizer. We realize we can't please everyone and that we aren't the vaporizer some are looking for.

Are there also some sleeper cells posting in other threads waiting for the word to.....


Your last two postings just killed any chance I ever had of buying this vape.

Really? I thought they were professional and appropriate. I think Davinci's slowness to respond here is probably indicative of someone taking their time to tread appropriately. If they really think there is a saboteur in our midst, then I am sure they are trying to address the situation without sounding whiney or jeopardizing any legal rights, which is hard. The rest of their post, the part that you didn't quote, was all about the customer experience and their commitment to making it great. I had just the opposite reaction to their last two posts.

The part where we are proud of our loyal customer base? The part where we're proud of the customer service we provide?

It's ok. We're not for everyone and if a forum post dissuades you from purchasing, I totally understand. I'm sorry, I just won't let wild speculations damage our brand. We go out of our way to provide the best customer service possible. Our return rate is less than 1% and of those 1%, we send out replacements that often arrive before the return unit is even boxed up and ready to ship back.

We just feel that if someone is paying $250 for a device that has a problem, we have a duty to make sure they are happy with it. We have an obligation to customer satisfaction. This user hasn't even bothered to call or contact us about a replacement. We are more than happy to replace the unit and will send the replacement via fedex overnight.

So, I'm sorry we won't be your vaporizer of choice in the future, but I hope you find the right vape for you. In the meantime, we'll continue to keep our reputation for the best customer service possible.

Hi I am new to this thread and have been lurking around it a bit, and there is a lot going on! I just wanna say that I am a newbie to vaping and am learning the lingo and such of these forums. I have been vaping for about 2 months now. I have tried a few different brands of vaporizers from friends and I have to say that the Da Vinci is definitely my favorite.
Being a female, I love the look and bought the white one. It is very sturdy and heats up fast which makes me happy. I have vaped in a crowded theater with it and no one was the wiser. Made the movie a lot more enjoyable :) It fits nicely in my small purse in the cell phone area and with the snorkel that I bought with it, I don't even have to take it out of my bag when I am out.
My only concern is the batteries and replacing them once they go bad. That may have been addressed in these discussions, but like I said there is a lot on here and reading 27 pages so far is a lot!

Unlike members, we have access to posters' IP addresses. We also have access to info from other sources-dealers, distributors, other forums, etc. So I can confirm that we do indeed have people posting here, from time to time, that have their own agendas. Not everyone here is honest about their intentions.

So I suggest you take your sarcasm, and thinly veiled taunt, to some other forum. As for losing a sale to you, I'm sure the company will survive it.

why are they double-coated? (the red/black coating+the see-trough sleeve around that)

Here is my interpretation. The wires are coated in a thin colored material to tell the different wires apart (so you don't mix up the wires). The outside is then covered in the thicker silicon for the added heat shielding.

Update:

I have been "burning off" the davinci for the past week a few hours a day. I set the unit to 430F and turn on the heater every 10 minutes. There seems to be less vapor emitting but it is still there. Although I still suspect the polyimide tape or its adhesive is the source of some of the rubbery vapor/smell, it also may be coming from the rubbery paint. I noticed when the unit was new the paint was perfect, very smooth, no defects. I am now noticing around the vent grid on the side and around the chamber on top where the unit is filled, the paint has warped and started to wrinkle up a bit. The left side of the unit(from the front) is still perfectly smooth, no defect. I am not sure if the front and back half are the same material/paint, but the warping seams to be more on the front piece of the unit.

I called Karma and they said that the different colors do have different compositions. I had a black one, they suggested I try the gray. They are sending it out today and are doing a "burn in" before they send it out. I really hope it was just a defective unit.

The opened unit clearly shows the high temp insulation over the plastic coated wires. What do you think is happening to that plastic once the high temp insulation heats up and the temperature of that plastic gets up to about 250 degrees F?

Yes, this is a very valid concern. The clear coating may be silicone but the insulation probably isn't. This same effect may be heating the black silicone ring on top of the chamber and causing the paint to get to hot and out-gas?

Manufacturer: What is the red and black insulation made of on the wires used?

That vapor you see could just be hot air with no foul compounds that may harm you..

My Volcano gives off hot air, it is completely invisible and has no smell what so ever. This is not just hot air.

I've used 2 different units and the only bad smell or taste I've experienced is at the end of the bowl, and that's ABV taste.

Have you had any experience with a clean unit? As I stated earlier ABV taste can very effectively mask the rubbery smell. I didn't detect it the first day when I used lightly with material. What color were the units?

But since more than half of your posts here on the forum are claiming toxic materials for various models, not surprising.

Seems to be to be concerned about heath, as are many MMJ patients. Even if this is another manufacturer or something, the information is welcomed, minus the claim that it is for sure the "plastic tape."

We still have a rule here about discussion of materials in a vape thread. Let's quit the speculation and comments about smelling something burning that's nobody's previously reported, and let DaVinci supply some info. Meanwhile anyone insisting on getting on a soapbox may just find their post subtracted and an infraction added.

Although I do agree on not having a materials discussion hijack a product thread, any information on possible materials safety specifically related to the product being discussed needs to be in this thread for everyone reading it to see. And my claim has been previously reported in this thread. The question is, as you have stated in some of your posted on this forum, how much toxin is acceptable. Each person will have different limits. I'm sure some on here don't care if the unit off-gasses while others will in no way stand for even the possibility of such an issue.

The red and black is the original insulation on the wire when it is manufactured, most likely not silicone. The see-through sleeve is the "food grade silicone," unfortunately it is not a heat shield so the wires inside are still getting to at least 430F.

I think my DV is suffering from more manufacture error :( . My unit has trouble charging. I have to either push and hold the plug into or slightly left in order for it to charge and buzz. This is fine when using the unit but I use it as my everyday go to portable so when I can't charge it over night when I fall asleep it becomes incredibly inconvenient. I only ever plugged it in at night and let it sit on my bed-side table so I don't know why this has happened. Would warranty cover a replacement? I would send it in but like I said it's my go to and currently only piece I have. I could try to take a video or shop around for a quick replacement piece, but I'm currently broke with no job, fresh out of school with the debt that comes with it, but I'm sure I could find something.

I should also add that the socket itself where the adapter plugs into the unit is very loose.
