Use precautions:
1. With the booster, knee folding will have a certain angle (about 45 degrees) to start the elastic effect. The principle is that the knee joint is not very flexible when the elasticity starts at 0 degrees.
2. A knee protector is equipped with three springs. When the knee is bent about 45 degrees, the rebound assistant starts to assist climbing, carrying heavy objects and seriously damaged knees. It is suggested that three springs be used for walking, climbing, running, and cycling. It is suggested that 1-2 springs be adjusted.
