We stand behind our products and their quality. We will warranty our models against any manufacturing defects for two years after the purchase date. All sales are final unless defected. Our models continue to surprise us on how well they stand up to repetitive use. Our customers tell us that they have held up to daily use for over five years…and continue to perform!  This warranty does not extend to any item that has been subjected to abuse, neglect, accident or improper use of flexion.  Keep the model movement within natural ranges of motion and use the models as instructed and they will provide years of service.  In the event there is an accident, we do repairs.
