Bests & Worsts Reviews from Amazon

At first these looked to be a good deal. 4 bands for a decent price. However after using them for less than a month, 2 of the bands have develop tears in them. I've had other bands such as X3, Quantum, Serious Steel and more and have used those for years without any developing any rips, nicks or tears. I've attempted to contact customer service on a few occasions but they have not returned any correspondence.
