Review on TRUE METRIX® Solution Solutions TRUEplus® by Josh Whitehead

Works well and as it should. I tested each bottle twice because I'm new to it. In each test, the maximum difference was 2 points. Although carton 2 and 3 were sealed the bottles were not tamper evident like bottle 1. Carton 1 was not sealed I believe because bottle 1 was tamper evident. Make sure cartons or bottles are sealed.
