^ how many pills/year wiill you test? If you test often and live in the US, dancesafe may be a better option. I like the reagent bottles over disposable. Plus their kits make it fast to the US
If you want to get dropper bottles then your only other logical choice is mecke... however.if your ordering ez test vials then mandelin becomes available which i like for ketamine detection... just look at the list of chems hey test for and decide whats most relevant to your intentions
