I wish I could say a Quantum Band never breaks but since it is not an iron dumbbell or kettlebell it is possible. Fortunately, 99% of all Quantum Band breakage is a result of poor attachment points or over-stretching with training. Both of these avoidable scenarios cause the band to tether or tear in a jagged fashion. However, at Resistancebandtraining.com, we realize mistakes happen and therefore if your band breaks we ask that you email us at (firstname.lastname@example.org) a picture of the broken band so we will review the claim. In most cases, if it is a first-time incident and it has not surpassed our standard 1 Year Manufacturer Warranty, we will replace the band with recommendations on how to prevent future training errors.
