Query: They break off

I bought one of these for each of my two bathrooms.They both broke off in the same place. The compression collar that connects cradle for the showerhead to the swivel ball cracked in half. Either the collar is not strong enough or the plastic is defective and stresses out from expansion from the hot water.In my opinion they were a total waste of money.
