"Goat Grip" appears to be a legitimate product. It's a putter grip that has received positive reviews from users and experts alike. The grip is designed with a flat side parallel to the putter face, which is a departure from conventional designs. This unique design is claimed to enhance the golfer's sense of and connection to the putter face. The grip also features a "Deep Well Shape" that sets the trail hand farther behind the face for increased stability. The placement of the shaft closer to the top left corner of the grip is said to help maintain the intended relationship between the grip and putter face, and to dampen unwanted shaft rotation. However, as with any product, individual experiences may vary, and it's always recommended to try it out personally to see if it suits one's needs.
