Backup ball cured.
I am a twice a week bowler. Average is 125. Many coaches have tried to rid me of my Backup Ball. Nothing has worked so I just struggled with it. My husband got me this device and I instantly began to throw a gentle Right to Left arcing Hook ball. I shot 145/ 152/ 148. I bowled one more game without the Wrist Restrictor and the backup ball returned. The device seems to give me a gentle tug in the correct direction, CCW. I am never bowling league with out it. This is no gimmick, it works.
