Defective products cause injury or harm to a consumer. These cases focus on holding manufacturers, distributors, suppliers, or retailers responsible for placing a faulty product into the hands of consumers. The defects can be related to design flaws, manufacturing errors, or insufficient warnings about potential dangers. In such cases, the injured party must prove that the product was defective, that the defect caused the injury, and that they were using the product as intended or in a reasonably foreseeable manner.
