THC Drug Test Kits - 20 Tests

I conducted 3 seperate test. One I knew was dirty. One I knew was clean. The last was unknown.I did test at the same time and made sure everything was as it directed.All three test came up Invalid.I did the test again to ensure this was right.Again the same thing.The quality of this product is not there.It was a waist of time and money.Stay away from this product...

Kept my friend from lying and going back to the drug. It gave very clear readings and easy to use.

Seems to work well. Much cheaper than the local pharmacy.

Really quick and accurate results!
