12 Pack-INVBIO THC 20 ng/ml Low Cut-Off Level,Urine Home Panel Marijuana Drug Testing Kits,Cannabinoids Drug Test Marijuana Dipcard,Manual in English & Spanish

This is a simple urine test that works just like a pregnancy test. You just dip for a few seconds and the result is almost instant. It’s nice to have these on hand when you have teenagers, haven’t had to use a test on them yet but tested it already just to make sure it works and see how it works. The results may not be accurate if you mess up he test so it’s good to have a practice round. These test kits are inexpensive, could be useful for all kinds of purposes, but could be just as effective just left laying around.

Got these for a good friend who is an intermittent marijuana user. We tested them out by having him take one and me take one. The instructions aren't the easiest to read but the tests were the most accurate over time and less expensive than many in the market claiming to test at a lower level than 50 ng.

Buyer beware!! Yes, I had THC in my system and alittle over weight. But I'm clean. It's been 2 1/2 months and it still shows that i'm dirty with THC. Made in China....I'm clean. I took another test through a proffesional dotor and i'm negitive. Very dissapointed and a waste of $$. No more China!!! If I could sent it back I will! I took 5 tests from it. Waste!!

I tried other test from local stores and they were just not accurate so I went through every test that Amazon offered and these seemed to have great reviews. These were super accurate. It was for a new job so it was important that my system was clean. These go down to the testing that labs use. If I ever need to buy test again I would definitely buy these again.

I buy these for my friend he says they work great

I used this product to test myself, the results were satisfactory, and very convenient because of the low cut off level, I would purchase agian.

My brother in-law needed a drug test to see if he had gotten second hand high from a party he briefly visited. He wasn’t actually smoking himself. Seriously, why would he lie about that? Well anyways, this did the trick.
