NO because that doesn't show the variance of this machine. You have to do multiple tests of the same material in order to tell what amount of variance there is between tests on that unit. If you tested 5 samples from the same bud, and it showed a huge variance between the samples then the machine is less valueable. If you test 5 samples and they are all close to each other then the machine is more valueable. Do you get it?

Now if you test 5 samples of the same bud and they all have IDENTICAL results I personally just think that looks fishy as hell.

You don't have to do 5 tests on every strain we just want to see one strain. Also having a lab test to compare the 5 tests to would definitely help show accuracy as well. No one is trying to give you a hard time, or cost you a bunch of money, but its the only way to really tell if this system is even close to reliable. Even running those 5 tests at $15 each your still at less then some lab tests. I would personally think knowing that your tests were actually accurate and not just BS would be worth that.

o_O WHAT?!?!!?
Are they seriously trying to charge that much for replacement trays?
That is incredibly uncouth on their part, if that's the case.

dont run 5 samples, just run 2 or 3. if each time its identical itsnot testing,.

I completely agree with both these comments. $15 for each little plastic cup is down right robbery. I bet you could 3d print new ones!!

It also depends on what he means by $15/tray.
If the device cost $450 with 30 trays, then x+y=z :lol: Cryptic Stoner Economists...

But if that is what they are charging for replacements, it proves my earlier point; the money is not made on the front-end product, but the back-end service. After a year of use, people will have spent more on trays than the device itself.
But hey...if it's that popular, I'll race you to the patent office to get our respective, reusable trays to market. :lol:

Results of testing for accuracy with the exact same sample of Girl Scout Cookies five times in a row. https://drive.google.com/open?id=0B4...TUk&authuser=0

Average THC came out to 20.5.

From my tests, I would expect AT MOST a +/- 2% deviation from the mean when testing any sample.

MyDx sample GSC THC.JPG

Based on your run, it looks tight, with a StdDev of only ~0.9%
I'd say it's fairly accurate in that sense. So if it measures that well in respect to a proper lab sample, then I'd say she's good to go (except for that mysterious replacement tray cost).

I have gotten no accuracy from mine at all. I have called them and they tell me it doesn't actually measure anything it measures sensor changes from smell and does math with the results from labs and comes up with an estimate. The tell me it doesn't actually measure cannibinoids. They described it more to me as a strain detector. I for one am a little mad. The results are just rediculous I have gotten pretty differing results with the same sample everytime.

Well, I don't know what to say in response to your words.
Do you have anything to back your story up? I did notice those "sensor" charts and wondered what they were measuring exactly since they weren't labeled.

Haven't run out of sample trays yet, but I'm wondering how effectively I could clean them with alcohol or some other cleaner? I don't see myself keeping up on ordering the trays, especially if they are as expensive as people in this thread say.

It's really going to be up to the beta testers to make or break this product, IMO. As I understand it, the analyzer has to interpret its sensor information into percents of chemicals present in a sample of cannabis, and it can only do this with accuracy if trained for accuracy. Imagine the "chemical nose" of the MyDx detects THC in 1000 strain samples, and a human teaches the machine what all the different kind of sensor readings from those tests represent. Then, when the MyDx tests a strain that it has not tested before, it will know with accuracy what the sensors are representing in terms of percents of chemicals present by comparison. It does not actually give you the results of other strains that have already been tested; it just uses the community database to constantly detect the chemicals present in your cannabis sample with more and more precision (given that the beta testers continue to train the community database by testing samples with known percents and correcting the MyDx results).

Perfect timing...

I have been researching steep hills results VS. SC Labs Vs. cannlab
Steep hill uses the Liquid/Gas Chrom. test equipment.
SC lab uses the Liquid Chrom. test also
Cann Lab uses thin layer Chrom. test

MyDx appears to be a handheld Chrom. tester...
The accuracy factor is subject to error on 2 of the 3 types of Chrom. test methods
Only one test method accounts for the errors presented in the otther 2.

The underline rat race that companies like steep & SC are in, is based on the strain data base.
The Data Base is were the POWER of control rest.
Which is why Leafly recently inked a business deal with Steep Hill.

If Leafly can use Steep hill data to compare its smoke reports...they become the authority of strain libraries.

The catch is in the data tolerance...Steep Hill has 34 strain records on file.
Leafly is notorious for genetic misprints of strains & half of their records are based on hear say.

SC Labs admits to the false readings & issues a corrective formula conversion.

This is why my corporation is focused on research...then examination...& finally classification.

I can say for a FACT, if the testing companies are not extremely careful with the generation of data...it will decay the future of cannabis profits. Secondly, If testing companies are not working in the favor of Cannabis pioneers...BIG Business will take the incorrect data & run a MUCK with it.

On the flip side, if a testing company works from WITHIN the cannabis community...the profits can be passed down to the end user. Ultimately leaving the control of cannabis futures to the millions of people that began its movement.

I'll share my results later, but yesterday I went into my dispensary and tested five or so strains. They only knew the THC% of one strain, Dementia, which the grower had told them was tested at 25%. My MyDx tested it at 25.50% THC. Was a pretty good feeling.

I happened to be at the hash bar at the local collective when the owner (of collective) and a representative from mydx walked in. They proceeded to come over and take some dabs of Chernobyl hash that we pressed out and then the owner went back to the car to grab the MyDX and test it. They used it on a Purple something and the collective tested it at 20.04 but the MyDX tested it at 24 something. What I learned is that the company doesn't test hash because of the many variables of what people make their hash with. But they also don't seem like a for real test of the THC as well it is just the vapor floating over some micro chip things and then the numbers popped up. The rep also stated how the little one use things can be used multiple times just use alcohol to swab it out. He laughed and said that his team was harassing him about that because he wanted a permanent testing thingy.

Anyways I was shocked as hell to see a rep from that company walk in, he was very forthcoming with the capabilities and was honest that it isn't 100% there just yet. He said that it is for people who want to find the certain effects they are looking for and not just about potency. Pretty cool gadget but I don't trust it just yet.

I contacted steep hill...

they offer a computer based system that works in the same fashion as the MYDX.
They issue the system for 5000.00.
You pay a 2000.00 per month access fee.
& you can test & compare your sample against their data base

No terpene profiles...just thc & cbd
