I prefer it over a kisser button, sets you into your anchor point faster. Mine has been on my hunting set up almost a year and it's still hanging on and hasn't budged at all and I shoot at the range a lot. The kisser button kept rubbing up against my lip to the point of it getting raw so I switched and won't go back. I had the smaller piece installed but I think on my new bow I'll put the larger piece on. I definitely recommend it.
