Problems
The Universal Nut Sheller has been less than successful in Ghana. First hand accounts relate almost universal breakage. Users can mitigate this breakage by pouring the nuts through initially at very broad settings and only later at finer settings, this practice does not eliminate the breakage and destroys the efficiency aspect. Groundnut shelling tends to be a social activity everyone engages in during their down time and there is rarely a need for a peanut sheller.
The Universal Nut Sheller proved incapable of shelling shea nuts in a manner useful for shea butter extraction for the shea nuts of Ghana. However, there are reports that it works for shea nuts from trees in Uganda.
The cost also proved a significant barrier. It simply cost far more to produce (even excepting the cost of the mold, transport of materials to the village, travel to the nearest town to find someone capable of welding the metal parts, etc.) than individual growers were able to pay. However, growers unions who made the investment have been successful.

Famous quotes containing the word problems:
“I’m no good at being noble, but it doesn’t take much to see that the problems of three little people don’t amount to a hill of beans in this crazy world. Someday you’ll understand that.”
—Julius J. Epstein, U.S. screenwriter, Philip Epstein, screenwriter, Howard Koch, screenwriter, and Michael Curtiz. Rick Blaine (Humphrey Bogart)
“While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.”
—Joan Lipsitz (20th century)
“Belonging to a group can provide the child with a variety of resources that an individual friendship often cannot—a sense of collective participation, experience with organizational roles, and group support in the enterprise of growing up. Groups also pose for the child some of the most acute problems of social life—of inclusion and exclusion, conformity and independence.”
—Zick Rubin (20th century)
