These worked great! I really like that it shows you the various levels. Very accurate and easy to use.

Worked great and loved being able to see the different levels. Used this to prepare myself for a new job and was very helpful to know how fast I was detoxing. Definitely accurate, was kinda hard to see the line sometimes but I feel like that’s pretty standard.

I had wondered how much thc would be detectable after partaking and this little kit did not disappoint in my wonder. I was more aware and knowledgeable for my upcoming test and being with in threshold. I thought this was great value for the money and it was also very useful.

I find these tests to work very well and accurate, I have tried several other types and have relied in this the most.

FALSE NEGATIVES- I took 2 of these tests and tested negative down to 20/15ng. 50ng is the screening level for federal testing, so under the assumption I was negative I went in for my urine drug test and tested POSITIVE at 70ng!!! This test was highly inaccurate for me and I was greatly mislead by the accuracy of the test. I am now having to figure out the fall out from an important test that I had prepared for with this faulty product. I do not recommend this product and unfortunately I would not trust the negative results.

So this test has the 5 sensitivities..the 300ng/ml and 200ng/ml were easy to see negative (2 lines is negative. 1 line positive. Opposite of pregnancy tests!) I can see the faint lines pretty easily for the 50ng/ml and the 15ng/ml, BUT the 20ng/ml takes some squinting to see so that batch of 20ng/ml might have questionably passed quality control during manufacturing. I took this test the day after a send out urine drug test they said was positive and the lab report pegged my thc levels at 5ng/ml which could be hemp product per what the report said. So my doctors office gave me a false positive from either a crappy strip like the 20ng/ml here that someone without great vision probably cant see. And per the instructions ANY 2nd line, NO MATTER HOW FAINT is a negative. So 5ng/ml of thc looks like this on this test.

Great

Easy to read, easy to use. Straight forward, simple, and fast. Affordable and practical. Like that it shows below level 20
