Query: Zipper busted after the third time used.

I have an iPhone 8 Plus and it fits but barely. It’s near impossible to hook up the headphone cord because it is so tight in the running belt. Also, they apparently use weak zippers because after the third time used, the zipper busted. Don’t buy this if you have an iPhone 8 Plus. Get a bigger one.
