To what extent does the responsibility of a manufacturer go? Is a customer's right respected by the producer in the course of a good's production? How can the rights of a consumer be defined in a "due care theory world" and how can the observance of those rights be verified? In other words, can we say that once a good is ready for commercial purposes the consumer need not worry over the safety or the accuracy of the good because someone who is in a better position has taken care of any possible inconveniences?
