I believe I've used it for about two years. There are no noticeable scratches or stains on the cup or shaft. There is no cup cover. Total Length: 76cm Weight: 58.8g Cup Capacity: 16ml Stiffness: Medium Manufacturer's Description: Just relax and swing lightly. The grip is designed to be non-slip, so grip it lightly and cast with the image of swinging the cup tip, relaxing your power. Of course, you can achieve distance with a traditional cast, stopping sharply overhead during the cast. For those who have struggled with long-distance casting, expect about 1.2 to 1.5 times the distance. For those who can already cast far, expect about 1.1 to 1.2 times the distance. However, you can cast with about 80% of your usual power.
