I have had mine on for a year now and its on to stay.I don't find the tinkering any more of a hassle then trying to get a good pass through on a prong style rest.I have tried a few things to see if I could make it affect arrow flight and it seems very consistant.I have one arrow that I clipped one vane from when I hit it.I shot that and it shot no different than any of my other arrows.Whether or not this is a biscuit issue is debatable.Every now and again a fletch will fly off but I lose more by piling them up in the target.I like it,its simple and reliable and inexpensive.Ron
