Why would someone purchase an Electric Milk Frother when a whisk works just as well?

The electric milk frother is generally not used for baking and someone would buy it for making cappuccinos, lattes and other coffee beverages that require frothed milk. The electric milk frother can make a large quantity of hot frothed milk very quickly as compared to manual whisks. Some people use the electric milk frother for just making hot frothed milk.
