We've got 3 of them. Have put various Ultraskins on them and never had one come off. I don't play with them much anymore though. I use Loctite also. While not a professional cue guy, I do have a cue lathe and have probably put 75 or so tips on, mostly Ultraskins, or lately some Triangles, and have only one come off. Turned out the ferrule was loose and I didn't catch it.
Maybe they are miscuing a lot or possibly not taking care of the cue and it is falling down on a concrete floor. Our Monday night league with 48 players and concrete floors, I hear cues fall and slap the floor 2 or 3 times every night. My teammate knocked mine down one night and took a bit to get the embedded grit out of the shaft. I don't stand mine next to hers anymore.
