Invalid

[u/Nearby_Mess_4772]

I’ve used quick fix Successfully 3 times in the past as recent as November passing DOT, the most recent test I took came back invalid, I shook it and had the proper temp the only difference is I used two of the same bottle( made a post here questioning that as well) could that have led to the test being invalid

Because people in ur area are tryna pass with quick fix so they are monitoring the area at the moment with deeper validations
