Rapid Response 2.0 Fentanyl Test Strips-5 Pack – Upgraded Drug Testing Kit with Micro Scoop – Fewer Cross-Reactions – Fast & Accurate Harm Reduction Tool for Overdose Prevention

Super faint lines!! Test several times just to be safe… Good product though just have to retest more than one time

I purchased these for a friend who is in active addiction. I have lost so many to this horrific and devastating disease of addiction, and fentanyl is all over the streets. She brought me something she found suspicious in appearance and asked me to test. Lo and behold, it wasfentanyl. $6 is so incredibly affordable, but saving a life is priceless. If I could give 6 stars, I would.

I like the privacy of buying test strips online vs the pharmacy. While I enjoy the occasional recreational products fentynal should be a huge concern for all of us. These strips have proved accurate and are fairly easy to use without requiring a huge amount of product.I use powder from different areas in a package or shave a tiny portion off a pill to test.Make sure you follow the directions perfectly.I would be so bold as to suggest parents or loved ones make sure young people have access to testing strips as they can save a life. In my generation we would drink and drive before a public campaign educated all of us and parents started being more concerned about kids feeling safe to call for a ride than facing harsh consequences about experimental behavior. We should all be the same about fentynal awareness.

They work. I was prescribed a fentanyl patch. When it was time to dispose of it I wanted to make sure there was no residue left. I first conducted a control test of the strips by cutting a small piece of the used/discardable fentanyl patch off and stirring it around in a cap of room temp water. The test came back as containing fentanyl as I expected. I discarded the patch remanents safely then washed the cap with soap and water and rinsed all the soap off and filled the cap again. I tested it again and it came back with 2 lines (no fentanyl).The strips work on real pharmagrade fentanyl. I hope this review helps readers make a an informed buy and be safe.

I appreciate this product and I think it's essential in this day and age to test, however the test strips seemed kind of flimsy and the results aren't very obvious or conclusive. I wish the lines that show up were darker (for peace of mind), and that the instructions were a little more clear. The test line only shows up if it's NEGATIVE so i'm not sure why there would be varying shades/super faint lines. How can there be varying degrees of negative? I think I expected more of the qualify of the at home covid tests we're all used to. We ended up using multiple tests at a time just to be certain of the results.

Amazing testing kit!

I don’t feel confident using these test strips. Even when testing pure water with no drug present, I consistently got a faint positive result for fentanyl—there was always a dim line at the T position, about 20% as bright as the C line. This makes it impossible to tell the difference between a truly negative result and a small amount of fentanyl. For me, it’s crucial to get a clear, unambiguous negative reading, and these strips didn’t provide that. I tested three separate strips from the same batch and saw the same issue each time.

the one that's positive is this product the three that are negative is cvs brand strips.... theirs comes with a scoop and a cup with exactly how much water to use. this is all tested in the same water with the same amount of powder..... which is right? out of 4 of these test strips, all were positive, the cvs ... all were negative is there a different kind of fent that these strips catch and the cvs ones don't?
