Yes a couple of peeps have tried this. I was not convinced it was worth the price - but I am a cheapskate.

There are others I just do not remember who?

I remember reading @FullDuplex posting his results of the tcheck vs lab tests, and there was quite abit of differences (tcheck was 10% lower than lab results.)

It would be a very nice tool to have, and maybe they made some improvements over the years!

I have one of these.
It was reading way too high for my tinctures, and I suspected chlorophyll was messing up the readings.
So I made some chlorophyll tincture out of nearly zero THC bottom fan leaves.
As expected tCheck gave an off the scale cannabinoid reading.

tCheck is a good chlorophyll meter that I now use as a paperweight.

What does this device "accurately" measure? I thought some type of serious lab. instrumentation, even CG-MS or surely some type of spectrography, is needed to determine cannabinoids concentration; and chromatography might even be needed to 'clean up' the sample (such as remove chlorophyll and interfering terpenes) before it's actually tested. Is it just a % light transmission meter; or a stripped-down version of an increasingly common industrial hand-held IR or other spectrometer?

Yup, @Builder0101
Has one.
Haven't seen him online in a couple of weeks.

I believe you have accurately described tCheck as a stripped-down spectrometer.
It measures the absorption of wavelengths that cannabinoids are known to absorb.
Unfortunately those same wavelengths can be absorbed by things other than cannabinoids. That's my experience.

But even though it doesn't meet lab. standards, it might be useful and cost-effective for some users (willing to accept a good amount of inherent inaccuracy). It could be an indicator of cannabinoid content good enough for individuals titrating their own oils, extracts, tinctures, infusions, etc. (what it's sold for).

My buddy has one and claims its close-ish.
You get what you pay for.
So, don't expect lab accuracy, right.

For those of us who leave herb in oil, or do long soak tinctures, the remaining chlorophyll messes up the tCheck results.
That implies that not getting all the chlorophyll out with fast washes will also make results questionable.
