It was easy to attach and locked securely. The bottom cap that covers the charging port is secure, you can see the charging light through the case skin. Very cool That transaction was super easy & fast (had the replacement the very next day) and easy, but not only that, I received an email from the company. Contras:El cable es un poco delgado, sino se tiene cuidado con un jalón se pueden dañar. I hadn?t bought shoes in about 3 years as I was wearing an orthopedic weight offloading shoe due to amputations I had on my right foot.
