good idea on the reagent kits. they work well as long as you know their limits. they won't tell how much of a substance is in the sample, or what adulterants are there with it. also, the colors for similar compounds can look very similar. and I don't think there is one for benzos (although I wouldn't expect your mystery tab to have a benzo in it). If you are aware of the limits, I think they are very useful tools to stay safe. But for the sake of harm reduction, I usually follow the "When in doubt throw it out" rule with mystery tabs.
