Review System
A Review System is a key feature of online marketplaces and e-commerce websites that allows customers to rate and comment on products, services, or sellers. It helps build trust between buyers and sellers by providing honest feedback from real customers. Think of it like a digital version of word-of-mouth recommendations. These systems typically include star ratings (usually 1-5 stars), written reviews, and sometimes photos or videos from customers. Companies like Amazon, Yelp, and TripAdvisor are well-known for their review systems.
