SwitchGrips SGC Standard Size Corded Swing Grips

2 of the grips were defective. after installing the grips, when you change the weights at the top, it just keeps spinning as the weights are no longer held in place. I can see this as a future issue to all the grips as there is nothing tight enough to hold it down. i believe the concept is for the metal tip to insert the shaft, but there is nothing to hold the metal tip into the shaft and it keeps sliding in a circular motion.

Just wasn’t for me
