Understanding case material
Case material is one of several spec fields the Mars Score uses to rank products in this category. Compare the two values shown above against the category-wide range to understand whether the gap is meaningful or marginal, and weigh it against the rest of the spec sheet before drawing a conclusion. A single spec rarely decides a purchase on its own.
