Customers say these mystery sunglasses are comfortable, lightweight, and offer great value for the price. Many appreciate the surprise element and find they love styles they wouldn't normally choose themselves. Common feedback includes satisfaction with the quality, fit, and unique colors like orange and pink lenses. Some mention receiving sports or wraparound styles that provide good coverage. However, several customers note sizing issues, with frames being too large for smaller faces or women's faces specifically. A few express disappointment when the style doesn't match their preferences, particularly regarding frame shape and lens type. Overall, most reviewers enjoy the gamble aspect and plan to purchase mystery pairs again.
