Davinci by Karma

I feel that the DV is a direct upgrade to the NO2. IMO it's an NO2 in a much nicer package.

Yeah, i figured as much but since i don't have one i thought i could be oversimplifying it.

I agree with Tim on both the upgraded no2 bit, as well as the unit getting hot - however, i'm quite used to having to hold my LSV with an oven mitt after the first20 minutes or so. the davinci at least stays cool on the bottom and ventless sides... that is one other thing about the solo, while the stems got hot, the unit never burned your hand from being held..

still, loving the davinci so far!

Is it hot? Hell yeah , but i seems like everything depends on the tehnique .... I got mine a while ago, and even forgot there is a heat at all ....

Oh, man. Just saw the davinci guys at sj hempfest, and they were selling the units brand new for $170. damn!! If you're on the fence about this...

Argh... After some toying with the oil cans, I realize how they work and how dumb my last question must have seemed... So let me rephrase a bit..

Has anyone tried using the oil can with herb via placing it directly in the bowl without the top piece of it on? I understand this may cause more convection than normally would happen but keeping the bowl clean while out and about would be a major plus!

Yes it was discussed back in the first 1/3rd of this thread. They found that you did not get much vapor but the flowers turn dark brown. Eventually everyone decided it did not work well enough for it to be worth the effort.

Sorry Slightly Medicated, but I have to ask if you're sure...

I've read this whole thread and while they did discuss using the oil can for herb, I don't believe how I suggested doing it is how it was tried. I remember them talking about it not working because the oil can sits higher up and it's too far to get good heat. Sounds like they were actually hooking it up like they would when using actual oils. Not 100% sure, but that's how I read it. I'll go back tomorrow and see if I can find it.

The Oil Cans were a bit of a disappointment to begin with and I could only get the faintest puffs of vapour. As stated above I really think it’s a waste using them for herb. The ‘oven’ effect is magnified in the Oil Can and I found that my herb was getting scorched rapidly. Even with the silicone top off the herb is cooked rapidly and little vapour is produced. I posted a video previously for a few mods on the oil cans to get them working more effectively.

This was the thing I was referring too. Maybe you are right that they are talking about it being in the upper chamber?

Well,one full day and ~10 sessions later, I have to say I am noticing the plastic smell more and more. It isn't so much a taste, but it smells like the back of a hot VCR. I emptied my chambers, bumped it to 420F, and ran it for 20 minutes. Tried again with empty bowl, still saw wisps of really super thin vapor, only visible in certain angles, exactly at the same rate and speed as the "outgassing" video another user posted here about 10 pages back.

I also feel this plastic is adding something to the high. It isn't as clean and I think I feel a bit of nausea. I really hope this smell goes away. Its super subtle, but when I see made in china + unexplained scents and gasses together, I have to worry....

the vapir no2 had the same issue (just worse it seems from reading the no2 thread). with the heater core of the davinci being nearly identical, do we have a navpir no2 rev1 on our hands? i really hope not,because i love this vape so far on every other category.

the davi ci rep was also going on about getting health/rohs certs and such. whats the latest on that?

edit: got a video of this elusive mystery vapor. its been "burning off" an empty chamber for over 30 minutes now, and smells nothing like herb/charred abv. smells like electronics... hoping time will resolve this one and that it is too early to tell...

Early on, many of us came to the conclusion that both putting herbs in the oil can and in the top chamber was ineffective. I believe we all experienced the same browning of the herbs but minimal vapor being produced. If you guys are looking for a better way to use thecans for oil, I suggest JRR's oil can mod found early on in the thread. It helps a lot in my opinion.

IM USING MINE ALMOUST TWO WEEKS, AND I NOTICED THE SAME MYSTERY VAPOR FEW DAYS AGO, burned it about 3 times on 430 till this moment, and nothin has changed :@ :@

I swear to Dear God its empty, and smells like plastic , and im using it about 2weeks

Sorry, i made it with iphone an i dont know how to trim video just wanted to show u guys the what iam seeing

That's not cool at all...

Thanks to those of you being volunteers and early adopters. I had a bad feeling about this vape but after these videos and reports I'm confident that this vape does not live up to my safety standards.

If you inhale plastic fumes it's not cool at all brother...

The one thing I will not compromise on a vape under any circumstance is safety. I've gone through lots of vapes and found lots of things that I view as dangerous, yet others use them still. That is why I now wait for reports like these. I hope those of you with phantom vapor can at least get your money back to reinvest in a safer vaporizer.

I would definitely discontinue use. I have never seen a vape do that when empty...not normal. That being said, make sure there is absolutely no residue from your flowers that is getting vaped. I have gotten vapor from an empty bowl before when drawing simply because of the honey buildup in there. But a plastic smell would lead me to believe this is not the issue.

It could be plant matter, but would it really survive 3burns on430 till batterys empty?
However i suspected it could be honey, and then cleaned unit almoust perfectly, however vapor remained
It seems like its not there when going till 400, but oh well... I was just using mine vulcano ...
Actualy there is problem after problem... Bought mine on ebay, thhen find out in this forum KARMA will break warranty if unit is bought not from autorized dealers... Then DEV TEAM contacted me here and said its gonna be ok , just reply to out
Email ..... As i did, but havent got any answer .... Now this .....
I had big expectations on this after luvin my vulcano, but it all came to this...

Maybe a thorough cleaning will eliminate the vapours. I think it could be honey buildup as well since the taste is quite nice after the plastic smell disapeared.

I believe the herbs would cover the plastic smell, that's why it doesn't smell when in use...

Yeah, its definitely not herb. I've waited for mine to cool completely (it was showing 91F when I emptied and scrubbed the chamber clean. 2-3 10 minute burns at 420F plus later, and the fumes coming out smell faintly of electronics and nothing else. If it was abv I suspect the charring smell would be overpowering and obvious.

This vape is 99% perfect for me, but this 1% plastic issue is a dealbreaker. I don't think the cave accepts returns, so I'm boned.. Again. Ah well.. Now it makes sense that the davinci rep stopped talking about the health.rohs cert they were waiting for. My guess is it failed horribly.. again, made in china by itself isnt so bad, but when i see china, and phantom gasses out of anempty chamber, then i start to worry..

heading out now to pick up an arizer solo...

Lets stay calm , and try not to loose last hopes

I got the vapor when I turned it on and up to 430 for about 5 minutes. I turned it off and did a extremely thorough cleaning. I spent about 30 minutes cleaning the inside and outside of the device with 99% ISO. I let it dry overnight. When I woke up I did another quick cleaning, and let it dry for an hour. I just did the same test and nothing visible came off the unit.

People that are experience gas, are you doing an extremely long cleaning before testing the "out gassing"?

I never had gas when I first got the unit, I don't have gas when the unit is clean. I only experience this when the unit has been used and not cleaned. Even after one load through the device there will be enough resin build up to produce vapor when it is turned up to high and left alone. Personally, to me that says the vapor I am experiencing is from left over resin/oil on the inside of the device.

From most of the video of the "out gassing" I have seen I see little bits of used plant material caked onto the device. They don't look clean. I could not see into the chamber of the one that had the lid closed.. so I don't know how clean that one was.

Personally, I am not really turning the unit above 400F when in use. At what temperature does the gas start/stop being produced for others?

I clean my device with ISO after every other time I get back from going out with the device. Once a week I do a thorough cleaning. I try not to let any resin build up on the device at all.

I am still not completely sold on the out gassing theory. I think we need to start with an unused unit in order to determine what type of vapor is being produced. There are to many control factors that can be affected by doing the test on a unit that has been used.

I would like an update from the Representative if they have received the results from their safety certification hey submitted awhile ago.

Kertong, i would wait before switching. Perhaps until the plastic smell subsides, because only brand New davinci had that weird smoke.
My take is that, while there is a plastic smell there should Be some off gassing ocurring which would stop after the smell diminishes.
If you show me a davinci used everyday with 2 months use and still shows that vapour as well as a plastic smell, i would start to be concerned.
