Ok first of the disclaimer and clarification. Yes I have been given a few test kits to try free of charge. Neither Colombo or TSB have control of what I choose to write. The reviews are purely my own and represent only my personal views. So quite a few people here already know that I am technically colourblind. Specifically reds and greens. So who better to give a test kit review that uses colour changes to someone colourblind ... Anyway, first up general appearances Packaging is good. Cardboard packaging has a plasticy finish to it which I am sure helps to keep the moisture out and helps prevent the cardboard falling to bits. Images on the back are clear and easy to follow.
