The Good: They we're very comfortable and squishy once broken in. Nice grip.
The Bad: Lasted only about 2 months and then the ribs started to tear.
Once all the ribs start to tear off and is left with the flat surface of the grip it starts to hurt when used. The good thing was that the grips were long enough that I rode and held them at the ends so one end wore down and then I just flipped the grip around to reuse the unused end so make em last longer. However this won't be good if you grip em in the middle.
