The rebounding damping technology, that the function in the same kinds of products sold in the market are not in common, means when you pull the drawer out to the bottom, it will has a process of soft closing and rebound, which can reduce the noise made by the things loaded in the drawer in efficiency. Moreover, because of the variable damping technology, which help to lessen the force of of the inertia made by the motion of the box when open or close it, and it will extend the useful life of the cabinet effectively. Therefore, it proved that the two-way slow motion cabinet have a longer useful life than the single soft-closing drawer system. And that is the reason why GRASSHOPPER is so popular in many countries all over the world.

反弹阻尼技术就是当你的橱柜抽屉拉到尽头时，有一个轻微的缓冲反弹过程，这样就减小了抽屉里面的装载物的碰撞声音，能达到更加实际意义上的静音，同时由于具备这种功能，在开合抽屉时就大大减小了由于抽屉的运动惯性对柜体产生的破坏力，这样就有效的延长了橱柜的使用寿命；所以使用双缓冲抽屉的橱柜比使用单缓冲抽屉的橱柜寿命明显延长，而市场上还没有具备这种功能的同类产品。
