Jer, I have installed only 2 of these, one on my own break cue and another on a friends cue. Haven't had an issue on either. My breaker has a phenolic ferrule and I pretreated the tip with thin CA. Then sanded lightly and then glued it on to the ferrule with Loctite control gel and have had no problems.
The other cue, I am told has had the same result, same set-up, same response.
