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

Works as it should.

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.

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.

Cleared up my suspicions

It arrived broken in the box, not sure how or why, black stuff wad oozing out of it and it smelled of a strong chemical. I'm just glad it didn't harm my skin.It looked like a cheap quality, I'd advise on looking into a different brand. I just returned it and didn't even try to purchase another, that's how disgusted I was.

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!!

Works fast but can be a bit intimidating reading results. QR code didn’t work for me. Other than that it worked great for what I needed it for.
