Drug Test Cup - G Overall a good product, easy to read test results under the strip of removed paper. However, I find the Evaluation Colour Chart confusing and matching the colours is not easy - we have conflict over colours and the way two of us see them differently. This does not give me 100% confidence that the tests have not been manipulated. The leaflet that comes with the test is generic and I had to contact the company to realise that there are only 3 colour evaluations that are relevant to my product. However, their chat function was very quick and efficient, I just think the leaflet could be a bit more professional considering the price of the product.
