A customer purchased a chainsaw from a retail store. The chainsaw was made by a well-known manufacturer of quality tools. It was part of a new line of power tools that were being offered at a significantly lower price than other comparable tools. Although the chainsaw included a kill switch, the switch was defective. Prior to removing the chainsaw from its container, the customer unexpectedly received a better chainsaw as a gift. He sold the first chainsaw to his neighbor. While using the chainsaw to cut down a tree in his backyard, the neighbor lost his balance and fell onto his wife, who was standing next to him. Due to the defective kill switch, the chainsaw did not turn off and the neighbor's wife suffered serious injuries. The neighbor's wife brought an action based on strict products liability against the customer. Will the neighbor's wife prevail? If not, whom might the neighbors prevail against? Explain.
