Fast! Accurate! Plenty of test strips!
Easy to use.it gives clear directions to make a solution to test pills or other suspected substances. It displays your results in 5 minutes time or less. It worked in 30 seconds when I tested it out.They are completely accurate, and I have tested them on substances that came positive, and I knew they were positive before testing just to see if they were accurate.So this is perfect for anyone with suspicions or concerns.Even people trying to get off of it or whatever. So easily worth it!

Accurate
Most people are unaware of the following:Fentanyl is highly lipophilic, allowing for rapid transport between blood plasma and the central nervous system• Fentanyl has been detected 19 days after last use• Norfentanyl has been detected 26 days following last useI used ONE single time and continued to test positive for norfentanyl (the metabolite of fentanyl) in my urine drug screens for 27 days! I was beyond shocked and even called my PCP to find out if she would refer me to a specialist to determine if I suffer from a slow metabolic disorder. I FINALLY had a negative drug screen on day 34!!!!! This test has a cut off level of 20 ng/ml which is higher cut off level than your typical lab company but if your urine analysis ONLY tests for fentanyl, you will be able to pass if you test negative using this…I hope somebody finds this review helpful. I wish I had know these facts!

I got quick results that came out like they should have. I would buy again if needed but that should never happen again.
