3 Compare the Quality of the Accessories
You can also find out a lot by look at the physical properties of the product. This works particularly well on the connection ends of your Apple cables, but it can be used for quite a few different products.
Apple’s own products feature single-piece components that are smoothly constructed and have rounded edges. However, if you look at counterfeit products, they tend to have squared edges, and the components look like many different parts soldered together rather than a single well-fitting piece. Components may also be wider, thicker, or longer than real Apple products if you are trying to compare them. Apple’s components are also reliably gold, silver, gray or metallic, right done to the nubs on your connectors, so be wary of clashing colors, especially black components or off-colors that just don’t seem right compared to other Apple products.
