You've obviously never used one, and then tried a knock off. They are not in the same universe when it comes to quality or feel.Exactly. I love how Apple uses "fluoroelastomer." Oh my God, just say "rubber." It's a rubber band. Nothing special about "fluoroelastomer."
And I bet it really does cost 5 cents. But since it has a giant Apple logo on it, people buy it.
Just like Glock guns. They're plastic. But they use "polymer nylon something." Just say plastic.
Edit: My day-1 sports band still feels great, but some pricey knock-offs I bought from Amazon lasted less than a month before they started to shine and feel terrible. Well worth the cost for the real thing.
