|Always inspect your bands or tubing for signs of wear, including small tears, abrasions, or cracks before use. Pay particular attention to the connection point. Always replace the bands or tubing with any sign of wear. With heavy use, such as in a physical therapy clinic, bands and tubing should be replaced every 1-2 months. The bands and tubing will not last forever, and will experience normal wear and tear with extended use. However, they should be safe to use as long as there are no visible signs of wear.
