Review on S7K Standing Putter for Men 🏌️ and Women: Achieve Perfect Alignment and Eliminate 3-Putts by Josh Allen

This racquet is great for balancing during practice. Rule 10b(2) prohibits placing anything on the putting green to indicate the line. Rule 10b(3) prohibits placing a club on the ground to assist in standing or standing up. In short, it's illegal (in my opinion) to pick up a stick and use it as a leveling tool. You can always ask the USGA. In addition, you can still use it as a regular racket or as an aid during training.
