Originally speaking of a spring does not shrink as it uses a hard line. If it is a legacy product it has been 1 or 2 years. However, this product will not last a month. It shrinks quickly and is not useful. Are they doing product inspection? It is doubtful. Please improve.
I wanted a softer spring, but even though I chose the softest object of the desired size, it was not what I wanted. Standards close to exclusive items can not be replaced with general purpose springs. I'm sorry.
