The casing can break due to a higher temperature water or quick change from cold water to very hot water. Such will happen very often in winter.
We recommend clients to use the product under 40 degree. Whenever the casing is reported to be broken, we will try our best to help send a new casing out your way.
When using the product, each client will get one free casing if it’s broken. From the 2nd one on, we will collect 50 rmb for the replacement.
