Residue Detection Multi-Drug Test Kit - Rapid Surface Residue Detector

Wasn't damaged during shipping and worked exactly as expected. Honestly this is a great product just be careful when using, it says to slip the sticks halfway down, break the tabs, shake then press the sticks the rest of the way down and when I shook it some of the liquid did splatter out but that was completely my fault. Very accurate and super easy to use.

Works as it should.

Followed the simple directions and cracked/crushed both ampules with the test liquid. One of the ampules was bone try so I couldn't complete the test. Now I'll deal with returning itm. Complete waste of time. I'm not real thrilled sending it back when I don't know if the sample I took even had any drug residue on it.

Pretty easy kit to use, the only part that sucks is it takes a bit of the substance to get a good test. Not much but enough to where if any doesn’t slide in there’s still some inserted into the test kit. Results were clear and perfect.

When you press the package on each side to break the (I call them glass vials) vials to release the acid you do not have to press very hard. Do it by sliwly adding pressure until they break. It might me a little surprising when they do because you can hear it and feel it but you cant see them break. Its very easy to use this kit.

One showed up already broken and useless. Other worked fine. If they could ship them damage free, wouldn’t be bad! Always nice to have handy when you tow/work on card in questionable areas. I’ve used the one I had and refused a tow without hazmat pay bc of residue found in the car. Very glad I had it. But when I needed again, it came out the package already busted and useless!!

Cleared up my suspicions

Firstly, what are the reagents present in the test? These aren't listed anywhere, so they can't be compared to tests acquired elsewhere. I assumed Marquis and Simon, but non-reaction for Simon is indicative of MDA, not MDMA. A positive blue reaction IS in fact the expectation for MDMA. As for the other reagent, there is not a single reagent that colors Heroin as vibrant purple. Comparing the results to the heavily tested and verified results list from DanceSafe makes this look pretty confidently like MDA, but I can't be confident at all without several more tests, and money spent on those tests.So, testers are looking at either potential harm if the test is this wrong on other substances or wasted "product" if they interpret these results as Heroin. Regardless, you're losing money buying these tests.Just get your reagents in bottles from a reputable seller and test directly. This is, well, bunk.
