Broke during 4.5 miles of 1st run after installing

When I purchased these I felt great that I had found them in the green and blue colors. Installed the green one and it only lasted about a week. I took it out of my swim bag and discovered it broken. Luckily I bought a pair because I had a run the next morning. Replaced it with the blue one, went out for run and at the 4.2 mile mark I saw it was partially tore. About a 1/4 mile later it fell off, completely broke.. $25 for junk!!!!!
