I read alot of reviews on this before I bought it and had mix feelings. I went ahead and purchased it to form my own experience because I too am a heavy smoker. I loved that the shipping was fast. I took a test before I started a cleanser. It came up positive of course. I started using a cleanser and waited a couple of days. When I took the test, it was negative with one of the lines kind of faint. I took it again and it was negative. This time the line was more visible. I would say the test strips are pretty much on point.

Accuracy is crucial for my future drug test results. These piss test strips are 100% accurate, just follow the instructions and will see proper results at the comfort of your own home. I've read the negative reviews, those folks are not following the proper instructions. I observed during my months long journey as I tested myself every 3-5 days and I noticed the second red bar kept looking more noticeable, it appears as the THC leaves your system it is reading more negative, it was not my imagination.

I see a lot of people leaving mixed reviews one video claimed it was showing positive results when it clearly said negative I don't know if people don't understand how to read the tests but they worked as promised I was a heavy smoker for 13 years prob wasn't minute out of the day I didn't smoke for the first month and almost 10 days I failed 5 different tests today I got a negative result with a faint line I have a drug test coming up for a job these let me see where my levels at and would def purchase again.
