Which product should I order?

You can choose two options: The Scale Control R Starter Kit (including a new cartridge) or just a new, replacement cartridge.
Are you ordering the Scale Control R system for the first time? Then select the Scale Control R Starter Kit.
Do you already own the Scale Control R and only want to replace the cartridge? Then choose the option to order only the replacement cartridge.
