Everyone loved the fountain. It was smaller than I hoped for initially but then realized 2lbs of chocolate go a long way. It was used for a party of about 25 adults/kids and the machine was turned on for about 3.5 hrs. The metal plate did not seem to warm up much, I think due to the good chocolate it did not get lumpy or hard. The instructions call for 2 bags of chocolate chips and 3/4 cups oil or Belgium chocolate. I did not use either or but the chocolate I used worked great. I would recommend spending on a good chocolate and not feeding your party guest with all that oil.
