  • Precise and Accurate
Size: 1 Count (Pack of 10)
These test strips work exactly as described. The included microscoop makes it simple to measure properly, and the instructions are clear and easy to follow — no confusion at all. Results show up quickly and are easy to read, which gives peace of mind. The packaging is compact and discreet, making it convenient to store or carry. The only small improvement I’d suggest would be including an extra scoop or two, but overall this is a dependable, well-made product that does exactly what it’s supposed to do. Highly recommended. ... show more

  • I *should be* positive, but couldn't test it.
Size: 1 Count (Pack of 10)
I'm actually on prescription fentanyl patches, so I thought I could wrangle one of my used patches (or my blood or...) and mess with the test enough to demonstrate a positive test, but that's just not the way these work. Read the description carefully - they're for testing if your dry "substances" have fentanyl, not if your kid/patient/SO/spouse anyone else is using fentanyl. Used as directed (and, in fairness, as described) I'm sure they work fine, but I was disappointed that I couldn't, perhaps uniquely amongst testers, demonstrate a positive result. ... show more

These are not effective. I ran it under tap water, and it said it was positive for fentanyl.

  • Huge on safety
Size: 1 Count (Pack of 10)
These test strips are an absolute must-have. They’re easy to use, clearly labeled, and give quick, reliable results, which provides real peace of mind. I really appreciate the straightforward instructions and the quality packaging—everything feels well thought out and dependable. Having these on hand adds an extra layer of safety, and that alone makes them worth it. Highly recommend for anyone who values staying informed and safe! ... show more
