This product works TOO WELL. Nothing gets by me now. At 20ng/Ml, it gives a fast, accurate result. At the price, it is great value.

Be cognizant that a very faint line through the T means negative for THC. You may assume it’s positive when the T line is very faint, almost indistinguishable. The C portion is always very dark which makes the faint T line seem negligible. Any line through the T faint or darker means negative for THC.

These work great. Definitely takes awhile to get it out of your system when you’re using a 20 ng/ml drug test because the levels are sooo low, but these really work. I definitely recommend.

Read and follow directions - some of the printing is small and I wasted three tests before getting it right.
