The PortionPro Rx was developed in the USA by a team with over 150 years of combined product development experience. For 2 years we attempted to work with U.S. manufacturers before realizing that in order to keep the price reasonable we would need to look elsewhere. We teamed up with a world class Chinese manufacturer that produces items for some of the biggest names in small appliances worldwide in order to bring you the highest quality product possible at a reasonable price.
