I don't have to worry about what's in any of the down town items we may receive. These take the tiniest amount of product 10 drops of water dip it for 15 seconds then wait 45 seconds and tah dah. These have saved his life at least 2 times for sure. Thanks guys great product and a great price.

Why wouldn't instructions be included with these? Is everybody just supposed to automatically know how to work a fentanyl test strips? Makes me mad!

One of the things I really liked about this product is the fact that it's able to detect fentanyl at lower quantities than some of the other tests I used before. That is very important for me because I know someone can die from The smallest amount.

Instructions included like 5 pages where it only ever refers to testing urine. There is no mention of testing powders or anything that isn't urine at all. The outside of each package is labelled "Urine Drug of Abuse Test".. Hope these work for testing actual drugs but I don't have much confidence in them, they were clearly made for urine. I feel that the Amazon listing is really deceitful

I had a difficult time resting non liquid items. Ended up just mixing solids with small amount of water and the test told me what I needed to know.

Dont be stupid, just get these, flex on others at parties and stuff while being safer

No, this product did not meet my expectation. Nowhere in the literature did it mention these test strips were only for urine. Still, they didn’t cost much.

Product worked as intended. Was able to detect fentanyl analogs in pressed pills
