The following is a sharing of customers’ personal experiences:
A customer had no knowledge of stair climbing machines.Bought an electric stair climbing machine online. Unfortunately, a serious accident occurred. When the customer was operating the stair climber to help his mother go down the stairs, the machine suddenly became uncontrollable, causing both the person and the machine to roll down the stairs.

As a result of the accident, the elderly man suffered multiple fractures and required multiple surgeries and a long time to recover.
