"best reverse insulator"
These are a little shorter than the fi-shock reverse insulator, but they stay on a lot better and are sturdier with thicker plastic. Some fi-shocks broke when the wire had some side strain, but not these Dare insulators. They are still more inclined to come off than the front side insulators, but the best I have found.
