These bands didn’t have the normal elastic stretch of a resistance bad. They are similar to a belt in a car that if you pull too hard it’s going to snap not stretch. Could’ve been a bad batch since some stretch better than others.
Response from supplier:
Upon reviewing your feedback, we suspect this may be related to a rare material inconsistency in recent production batches. We’ve immediately initiated a full quality inspection of all current inventory and are working with our suppliers to enhance material testing standards.
