I haven't used Quora or any other platforms to research products or services before making purchases. However, Quora is a popular question-and-answer platform where users can ask questions and receive answers from the community. Many people use Quora to seek information, opinions, and advice on various topics, including product recommendations and reviews. It can be a helpful resource to gather insights and perspectives from individuals who have firsthand experience with certain products or services. It's always a good idea to read multiple responses and consider different viewpoints to make informed decisions about products or services you are interested in purchasing.
