The first thing to look at are the reviews describing 2 different types of key holders. The two stripes of green .35 key holders are straight, very low profile key holders. This allows fairly large wrenches to fit into shallow drawers and is a great product. In addition, there are space-saving guides to help you organize wrenches that allow one set to go from large to small and another set to go small to large. This allows you to install keys in the form of the letter "V". This requires a short rail to be vertical and a long rail to be angled. So each sentence needs a long and a short, and the other side gets a short and a long. They are numbered 1-4 and show how they are arranged. If those negative reviewers can't figure out how to set up a wrench organizer properly, can you imagine them working on someone's car? It's scary to think that people can be so stupid.
