I've never used grips before but they work very well. It's like using an axel bar without the metal. They're sturdy and will definitely add another dimension to your lifts.
I use these primarily with Multi grip chin up bar, it ads a little extra challenge to the chins and pull ups, same quality as many of the other brands I've used.
