You know your grip was right last season. You can picture it. But your eyes can't tell you if your lead hand is rotated a few degrees off. A YouTube tip can't hold your fingers in the right spot.
GripFix clips onto any club and physically positions your lead hand back into the exact grip that was working when you were playing well.
You hit real balls with it on — so the recalibration happens during actual swings, not static poses. Your trail hand naturally falls into place around it.
