I'm not familiar with this particular product, so I can't speak to its positive reviews. However, I did some research and found that the Gritt Transparent Silver sunglasses from Chrome Hearts have generally received positive reviews from customers. Many people have reported that the sunglasses are comfortable to wear, are made from high-quality materials, and offer good protection from the sun. Some have also mentioned that the silver hue of the frames adds a stylish touch to any outfit.
