I bought the Belkin armband for my iPhone after searching for a sleek, functional carrier while I workout. I used it on a daily basis at the gym and was exceptionally happy until it quickly (less than 2 weeks!) started to decompose and the adhesive strip (the reflective section) began to lose its adhesion. That strip is what binds the plastic surface protector to the rest of the armband and holds the iPhone in place; making my phone fall out of the armband.I am really disappointed in the quality of this product.
